Power problems stop a shoot faster than almost anything else, so you need to know your rig's voltage and current before you plug anything in 34. Feed accessories from the sled's own Lemo outputs, not the camera body 12, and for an Alexa switch the sled to 24 V mode and use a cable wired for the 24 V pin 11. If the camera shuts down, suspect a sled that can't deliver the current, with thin wiring, wrong cables, diode losses or weak batteries as the usual culprits 50515253.

The questions 10

How do I power wireless follow focus, monitors and other accessories from my rig?29 threads · latest 2026

In short

Feed accessories from the sled's own Lemo outputs through a splitter box or custom cable, not from the camera body 12. Check each device's voltage and the total current before you plug in 34.

How the pros do it

  1. Use the sled's Lemo outputs for the accessories rather than a 12 V battery tap, because those outputs are typically better dimensioned for the load 1.
  2. Split the power with a box, not a daisy chain, because stacked Y-cables get unwieldy and every stage has to carry the total current 4. A 2-pin Lemo to four-way P-Tap breakout box ran a Bartech transmitter and a microwave transmitter from one battery without exceeding typical sled wiring capacity 5.
  3. Match each device's voltage, because the Blackmagic SDI to Analog downconverter tops out at 12 V and will not power on at 14.4 V 3. A car-USB charger gives you regulated 5 V at 2 A or more from up to 14.4 V in, and a 5-6 V AJA model can be damaged on a higher-voltage pass-through 67.
  4. Keep accessories off the camera body, because a RED cannot reliably handle draws from non-RED peripherals 2. Mount the follow focus on the sled with its own power instead 2.
  5. If one power connection is too weak, split the loads, for example by running the camera from handgrip batteries on a Flyer 8. On a single Flyer connection, switch on the follow focus receiver before the camera so the startup surge does not shut the camera down 8.
  6. Use hard-shell D-Tap connectors and wrap multi-tap boxes in velcro or tape so nothing pulls loose or goes in backwards 9.
Caution

Low-quality D-Tap connectors with soft plastic housings allow reverse-polarity insertion, which can damage wireless transmitters and camera power systems 9. Powering AKS accessories from a 12 V battery tap risks ground loops that can damage BNC/SDI ports 1.

Opinions differ here

Operators still argue over 12 V versus 24 V 1. One operator routinely flies 12 V systems without issues, using two Blueshape Mini Granite 140 batteries 1. The other camp runs 24 V with step-down converters, but two D-Tap 24-to-12 V step-down splitters failed within days on a Venice 2 rig 1.

What changed

Earlier, in 2007, operators ran follow focus motors and wireless receivers off the camera's D-Tap 10, today, in 2026, they power AKS accessories from the sled's Lemo outputs instead 1.

How do I power my Alexa or ARRI camera from my sled?29 threads · latest 2025

In short

Switch the sled to 24 V mode and run a cable wired for the 24 V pin to the camera 11. The ALEXA 35 is a native 24 V camera, so it needs that setup 12.

How the pros do it

  1. Switch the sled to 24 V mode and use a cable wired for the 24 V pin 11. A cable carries 12 V or 24 V, never both, so stock both variants 11.
  2. The ALEXA 35 shares the Mini connector but needs 24 V to start, so a Mini cable wired for 12 V won't power it up 13. Wrong wiring doesn't damage the camera, it just fails to start 13.
  3. On a Zephyr, the cable to an original Alexa is 3-pin Lemo to 2-pin Fischer and must be wired for 12 V or 24 V to match your battery plate 14. To reach an Arri Mini, use the adapter from 3-pin 0B Lemo to 8-pin 1B Lemo 15.
  4. The Alexa takes 10.5-34 V DC and wants a source good for at least 100 W 16. Two bricks in series can pass 34 V if each is over 17 V fresh, and then the camera rejects power 16.
  5. Check current, not just voltage, because a measured 24 V doesn't guarantee enough amperage 17. A Master sled's 16 AWG wiring and 15 amp breaker handle an 85 W Alexa at roughly 3.5 amps at 24 V 18.
  6. Keep a backup, because the camera automatically uses whichever source has the highest voltage 19. Sled batteries discharge faster at 24 V and camera power is lost if one fails, so watch voltage continuously and carry an onboard backup battery 11.
Caution

A Gold-mount-to-XLR battery eliminator fed with a 24 V cable puts 24 V on the P-Tap and 12 V accessory connectors, which risks destroying attached equipment 11. Flying 26 V batteries on a 24 V sled doubles voltage on the 12 V and 24 V pin outputs and creates unsafe conditions 24.

Opinions differ here

Most operators say 24 V halves the current draw compared to 12 V and that cameras run more reliably on it 21. One operator has run Alexa Mini and Mini LF trouble-free at 12 V for years, using hot-swap battery changes with an external 12 V auxiliary battery at the dock 21. On the Alexa, 12 V batteries are not recommended because they quickly discharge below 10.5 V 16, yet another operator ran it at 12 V to get better runtime on PAG 95e batteries 22. Operators also still disagree whether 12 V parallel or 24 V series gives better real-world battery life 23.

What changed

Earlier (2004) the EFP Steadicam® ran 12 volts and could not power a 24-volt Arri SR3 without modification 20, today (2023) you switch the sled to 24 V mode and use a cable wired for the 24 V pin 11.

Can I adapt V-mount and Gold Mount batteries or plates on my sled?28 threads · latest 2025

In short

Yes. You can run an adapter plate between the two standards 25, or swap the plate on the sled itself 26.

How the pros do it

  1. Use a V-mount to AB adapter plate if you need a quick fix 25. Keep adapters for both directions as backup, so you can use batteries from colleagues or rental houses 26.
  2. Soft Velcro on both the sled mount and the adapter helps damp it 25.
  3. It reduces vibration and holds up better over time than an adapter 26.
  4. To swap the plate, unsolder the old one and solder positive to positive and negative to negative 27. Check polarity before you resolder 27. On a V-lock plate seen head-on, the far left pin is positive and the far right is negative, so verify with a multimeter 28.
  5. V-mount and AB have different screw hole patterns, so you may have to drill and tap the sled 27. A Zephyr bracket already has holes for both patterns 27.
  6. A GPI PRO is machined for Gold Mount on its Bottom Stage, so direct B-Mount is impractical 29. A PRO2 base can take V-mount batteries through an adapter cable with no physical modification 30. On an Axis, one operator built a Gold Mount plate and a V-Mount plate in about 30 minutes for roughly 35 USD 31.
Caution

V-mount batteries have been reported to detach and fall off, and that can damage mounted gear like monitors 33. On a front mount installed inverted, pressing the release button without a hand under the battery can drop it 34.

Opinions differ here

Some operators say adapter plates work reliably, and some use them as their default system with backups 2632. Others say adapters add play, height and vibration, and that a dedicated plate is the more stable choice 2526.

What changed

Earlier, in 2006, adapters were seen as a vibration-prone second choice to replacing the plates 25, today, in 2025, operators build two interchangeable Gold Mount and V-Mount plates in about 30 minutes 31.

Why won't my battery charger charge or recognize my battery?26 threads · latest 2026

In short

Usually the charger is too old or its firmware is too old for the battery 3536. Dirty contacts or a faulty battery are the next suspects 3738.

How the pros do it

  1. A 2401 needs firmware 3.6 or higher to charge Dionic batteries 36. A Dual 2722 needs 3.6 or later for some Titon Micro 150 units 39.
  2. A 2702 can go to 5.8, a 2401 to 4.6, and a TWQ has two chips that go to V22 40. Ritter Battery sold a 2401 chip for about $75 36.
  3. Clean the contacts. Use a pencil eraser on the brass contacts and pins 4142. Dirt or corrosion can break communication between charger and battery 42.
  4. If you get NO COMM on a Quad and a Titan, suspect corrupted firmware in the battery itself 38. Cleaning won't fix that, so get charger firmware to 5.8 or newer 38. A battery under warranty needs the factory firmware reset 38.
  5. On a Dionic 90, try a paperclip in the small hole next to the display 43. On a Titon Micro 150, press the reset button in the seam above the display 39. If it is deeply discharged, connect it for about 30 seconds, disconnect, and repeat around 20 times 39.
  6. A Quad 2000 current fault means one battery has a shorted cell, and the charger stops charging everything 44. If a PAG AR304 cycles through all its lights, unplug it and let it cool, and check that the vents aren't blocked 45.
Caution

Take a battery in hold status off the smart charger right away, because continued charging can cause internal damage, melting and venting 37. Anton Bauer chargers have been reported to arc and burn resistors when plugged in, and overnight charging makes a failure more likely to go unnoticed 49.

Opinions differ here

Anton Bauer and other makers say lithium-ion packs should only use chargers from the same manufacturer, because the protection circuits have to match 46. Other operators report that most V-mount brands charge fine on each other's chargers, and that an IDX VL-4S worked with Globalmediapro 190Wh batteries 47. On digital Trimpacs, one side says an LCD digital charger is required 48, while others charge them on quad chargers without a display 48.

What changed

Earlier, in 2006, a charger had to be a 2000 series or later to charge Hytron or newer chemistries 35, today, in 2015 and 2016, a replacement firmware chip is the usual fix for chargers like the 2401 and 2702 4036.

Why does my camera shut down or lose power on the sled?23 threads · latest 2026

In short

Most often the sled cannot deliver the current the camera pulls, so voltage sags at the camera input 5051. Thin post wiring, wrong cables, diode losses and weak batteries are the usual culprits 525351.

How the pros do it

  1. Measure voltage at the camera input under load, not at the battery, because a multimeter can read normal while the camera starves 5053.
  2. Check the camera cable first, because a 12V cable routed to a 24V camera is the most common cause of ALEXA 35 undervoltage alarms 53. Carry a second original ARRI cable for comparison 54.
  3. Add up the current of every device instead of only checking voltage ranges 55. Give the hungriest device, usually the transmitter, its own feed 55.
  4. Upgrade the batteries, because operators report better stability with three or more batteries instead of two on Trinity rigs 56. V-Lock batteries rated below 8 amps gave about 40% dropout when switching to a depleted unit 56. On Trinity 2, three 12 V batteries or BeBob 24 V batteries worked, while two Gold Mount batteries caused intermittent shutdowns 57.
  5. Fix undersized wiring, because one operator swapped 22 AWG for two 16 AWG cables and cut calculated loss below 4% 58. Otherwise run the camera from an on-board battery or a 24 V setup, which cuts losses to about one quarter of 12 V 51.
  6. Before swapping a sled battery on an ALEXA 35, set onboard battery priority in the camera menu or disconnect the camera cable 59. Swap around 25 V, since the camera ran reliably down to about 24.6 V under load 59.
Caution

Check PTAP-LEMO cable polarity with a multimeter before connecting, because a reversed cable can permanently damage a Bartech 63. A battery-to-sled connector that gets hot means too much resistance in the path 58.

Opinions differ here

Operators don't agree on the cause on Trinity 2 rigs 6157. One side blames current spikes from the motors under load, with demand rising into the high teens of amperes, against a calculated 6 A steady state 57. Another found radio interference from wireless microphone transmitters near the sled 61, and some blame Firmware 3.0 62. Technicians suspected a defective voltage regulator in the camera in some ALEXA 35 cases 54.

What changed

Earlier, in 2005, lithium-ion current limits and startup spikes of up to 18 amps were blamed 60, today, in 2026, operators point to motor current spikes on Trinity 2 and thin sled wiring or two-battery setups 5751.

What are the connector pinouts for my sled and camera power cables?23 threads · latest 2026

In short

There is no single pinout, so you check your exact rig and camera and meter the cable before you plug in 6465. Arri's 3-pin Fischer is pin 1 ground, pin 2 +24V, pin 3 start/stop 66.

How the pros do it

  1. Meter every cable before connecting a camera, because pinouts differ by region, manufacturer and even rental house 64. Some Artemis units, original Sachtler versus ARRI-built, have reversed pinouts 65.
  2. Arri 3-pin Fischer RS: pin 1 ground, pin 2 +24V, pin 3 start/stop 66. Pin 3 also puts out a shutter pulse while the camera runs 67. The 2-pin Fischer BAT connector on an Alexa is pin 1 ground, pin 2 +24V 68.
  3. Panavision 24V battery 3-pin XLR: pin 1 +24V, pin 2 ground, pin 3 unused 69. The Panavision 12V accessory connector is a half-moon Lemo FFA.1S with pin 1 positive, pin 2 negative, pin 3 not connected 70.
  4. GPI Pro power output (Lemo 1S.303): pin 1 24VDC, pin 2 ground, pin 3 12VDC 70.
  5. For XLR, 24V 3-pin European gear is typically pin 1 negative, pin 2 positive, while US gear is often the opposite 64. An Arriflex 12V battery 4-pin XLR has pin 1 ground and pin 4 +12V 71.
  6. For an Artemis, the pinout is in the Artemis manual, and if you are still unsure you contact Tiffen or ARRI 65. The Flyer LE top stage has a 3-pin FGG.0B.303 Lemo, but the thread did not settle its pinout 7273.
Caution

Reversed polarity has destroyed a monitor on an Artemis 65. Wrong wiring when soldering a cable can also damage equipment 69.

Opinions differ here

Operators differ on the exact Lemo series for the GPI PRO 12/24 V connector, 1S.303 or 1B.303 74. The 2012 thread gives it as a Lemo 1S.303 type 70.

Can I get my old batteries recelled, and is it worth it?26 threads · latest 2020

In short

Sometimes yes, but it depends on the model, and options have shrunk since Ritter Battery closed 75. Dionic packs recell well at roughly one-third of the new price 76, while Hytron 50 packs are usually cheaper to replace 77.

How the pros do it

  1. A recelled Dionic 90 costs roughly one-third of a new one and can match or beat new capacity 76. New Hytron 50 packs are cheap enough that replacing beats recelling 77.
  2. Specialists give faster turnaround and better results 78. Recelling can also damage the Hytron 50 heat sensor 77.
  3. Check the specs and quality of components instead of assuming every rebuilder uses the same standard 79. One receller used genuine Samsung cells rated for a continuous 10 amp draw, and those packs exceeded original capacity 80.
  4. Recelled packs charge normally in newer Anton Bauer chargers 80. Some recelled Hytron 50 units fail on the Interactive 2702 PowerCharger but still run on a PAG Pulsar or Quasar Analyzer 81.
  5. It does not reset after recelling, so one operator adds a label noting the extra cycles 76. Recelled packs can also weigh slightly less or more than the originals, so recheck your balance 8180.
  6. Anton/Bauer offers up to 25% off list price when you switch from competitor batteries or recelled units 75. Dionic HC was on promotion at $330 in 2014, which sets your price to beat 76.
Caution

Don't swap in a different cell chemistry on your own, because the pack's microprocessor and charging electronics are calibrated for the original chemistry 83. Overcharging lithium ion cells beyond 16.8V can cause fire 83.

Opinions differ here

One user got 12 to 14 months from recelled Hytron 50 packs against 2 to 3 years from factory packs 81, and another saw them fail within a year 77. Others report recelled Dionic packs matching new capacity 76 and recelled Dionic HC and HCX packs holding up long term in broadcast work 80.

What changed

Earlier, in 2004, several vendors recelled packs for about 1200 to 1500 dollars per ten batteries 82, today in 2020 Ritter Battery has closed and Anton/Bauer offers no recelling 75.

How do I wire multiple batteries on my sled safely?17 threads · latest 2026

In short

Wire them in parallel with a diode on each battery's positive line so they can't charge each other 84. Use a high-current Schottky diode or an ideal-diode block to keep voltage loss down 8485.

How the pros do it

  1. Put a diode on the positive line from each battery when you wire two in parallel 84. Without it, the weaker battery trips its protection and stops supplying power 84.
  2. Pick a Schottky diode rated for the current, because it drops less voltage than a standard diode 84. Budget about 0.7 volts of drop per diode 84.
  3. For three batteries on the PRO Battery Hanger 2 or 3, use the Cramped Attic three-way parallel block with ideal-diode circuitry 85. It adds virtually no voltage loss and combines all three slots into one 12 V source 85.
  4. If you build a custom second plate for a Zephyr, include a rectifier diode to stop back-charging between batteries at different charge levels 86. Without it, batteries can lock out 86.
  5. Remember that paralleling 12 V batteries kills 24 V mode 87. On the M2, the switch on the third battery paddle sets parallel to the 12 V rail or series as a 24 V booster 88.
  6. Keep batteries on a Y-cable in similar condition and at a similar state of charge 89. Hytron 50s can't carry high-current HD cameras plus accessories, so use Dionic HC 89.
Caution

A parallel jumper block can generate significant heat, so consider added cooling 87. Routing all the amperage through a single cable run raised overheating concerns when several high-draw accessories run at once 92.

Opinions differ here

Some operators say two fresh, matched lithium-ion batteries can run in parallel with reduced risk even without diodes 84, and that V-Lock batteries can typically be paralleled without protection 91. Others say modern batteries must be decoupled with diodes or one battery sees the other as a load and shuts down 85, and that age and charge cycling make diodes more important 84.

What changed

Earlier, in 2005, sleds used plain diodes and regulated supplies to manage mixed batteries 90, today, in 2023, accessory blocks with ideal-diode circuitry combine batteries with virtually no voltage loss 85.

Ask a follow-up
How do I convert or regulate between 12V and 24V on my sled?17 threads · latest 2024

In short

Switch the sled between modes rather than converting: two 12V batteries in series give 24V, and in parallel they give 12V 93. To feed 12V gear from a higher voltage, use a regulator or converter rated for the amperage 9495.

How the pros do it

  1. On a Zephyr, fit the 12/24V adapter plate with its toggle switch 93. In 24V mode each connector gives 12V or 24V depending on the cable pinout 93.
  2. On a PRO sled, use the 12V jumper block for parallel mode and hot-swapping 96. The 24V mode needs cold swaps, and that jumper block is no longer made 96.
  3. Remember that wiring 12V batteries in parallel kills 24V mode 87. On CineLive, modify a dedicated jumper block and put the Schottky diodes in the block, not under the battery plates 87.
  4. Treat every cable as single-voltage 97. Check it by unscrewing the 3-pin coupling nut, using a multimeter, or reading the voltage on the camera 98. A cable wired for 12V will not run an ALEXA 35 even with the sled set to 24V 98.
  5. To step down for accessories, a 7812 handles about 1A and needs at least one capacitor 95. For bigger loads, the Alfatronix PV12i takes 17-31V to 12-13.6V at 12A with ground isolation 99.
  6. Size the regulator to the load: 1A covers a transmitter drawing up to 300mA, but a 3A light needs a bigger unit 94. Check that accessories tolerate fresh-charge voltage, which runs about 17V on 12V systems and 34V on 24V systems 100.
Caution

A dual-voltage cable used in 24V mode will destroy 12V accessories on the sled 97. A badly designed home-built regulator circuit on set risks equipment damage or fire 95.

Opinions differ here

Whether the Zephyr's 22AWG wiring copes with power-hungry cameras like the Alexa or Epic is disputed 93. One side says wiring is the limit above 90-120W and that 24V cuts amperage and heat 93. The efficiency gain of 24V is also debated, since the Alexa draws the same wattage at either voltage 96.

What changed

Earlier, in 2006, you rewired the Archer post for 24V or ran a second battery externally 101, today, in 2012, a Zephyr takes a plug-in 12/24V adapter plate with a toggle switch 93.

Can I fly with lithium camera batteries, and how many?13 threads · latest 2023

In short

Yes, but keep them in your carry-on, not in checked bags 102103. Under 100Wh the sources give no quantity limit, and above 100Wh you get one on the device plus two spares 104.

How the pros do it

  1. Read the Wh rating on each battery first, because 100Wh is the dividing line in the sources 104.
  2. Batteries under 100Wh have no quantity restriction for air travel, so a 95Wh battery is the easy choice, and 95Wh units are common in stabilizer work 104103.
  3. Batteries over 100Wh are limited to three per passenger, one on the device and two as spares 104. Another thread puts batteries between 100Wh and 160Wh at two per person 105.
  4. Cover the terminals with tape and give each battery its own compartment in the case 105106.
  5. Carry printed manufacturer documentation that states the wattage, because it helps with airline staff and inspectors 106.
  6. Check your airline's own limits before you fly, because airlines can be stricter than IATA guidelines 107. In the EU, passenger flights allow batteries in carry-on only, typically around 100Wh each 103.
Caution

Spare lithium-ion batteries belong in carry-on luggage to minimize fire risk 109. Loose spares in checked luggage have drawn penalties of up to tens of thousands of dollars 106.

Opinions differ here

One thread says lithium-ion batteries in checked luggage violate US DOT rules and can bring FAA civil penalties 109, while another reports travelers who sent Dionic 90 batteries through cargo without incident 110. A 2022 post says a battery attached to a device may technically be checked, but security staff interpret that inconsistently, so carry-on is safer 102.

What changed

Earlier, in 2007, the sources described a cap of two spare batteries plus one installed in the camera 108, while today, as of 2013, spares under 100Wh are unlimited and batteries between 100Wh and 160Wh are limited to two per person 105.
