Converting a 3A Steadicam power base from 12V 3A to 24V NP-1 batteries and evaluating performance
20 years old. Gear and prices may have changed since.
What the thread found
- NP-1 batteries are thin and have limited current supply capacity, making them unsuitable for equipment with high power demands like film cameras, follow focus systems, and video transmitters.
- NP-1 batteries perform adequately for low and steady draw applications such as audio mixers, video cameras, and LCD monitors.
- Some users reported poor performance from certain Switronix Pro-X NP-L60 batteries, including failure to hold charge and rapid depletion from full capacity.
- IDX NPL7 batteries have been recommended by sound professionals as a reliable alternative to NP-1 batteries.
- Anton Bauer conversion kits are available that allow mounting a full-size battery brick on the back rails of a 3A unit, with optional mounting of a second smaller battery on the bottom for achieving 24V output while maintaining dynamic balance.
- IDX batteries in NP-1 form factor are lightweight, affordable, and suitable for moderate-demand applications, though still limited compared to larger battery systems.
Depends on
- The Switronix battery issues may be specific to certain units or batches and manufacturer contact was planned but results not reported.
- The Anton Bauer conversion kit details and current availability are not fully documented in the discussion.
- Personal experience reports are based on individual setups and use patterns, which may differ significantly.
