What the thread found

• An AB mount plate can be attached to the top of a Hyperdeck Shuttle when paired with a PRO Battery Rack III, providing a third mounting position for additional equipment
• The internal mini din co-ax connector on a Hyperdeck can be replaced with full-size BNC jacks by soldering the co-ax leads directly to the motherboard where the mini din connections terminate
• Removing the internal battery from a Hyperdeck creates space in the front panel for installing larger connectors like BNC jacks and an 8-pin lemo connector
• Power can be routed through a lemo connector soldered to the two pins on an AB mount plate, with a regulated 12V feed soldered to the motherboard at the DC jack location
• An AB mount configuration on a Hyperdeck mounted to a monitor bracket makes SD card access difficult, and the battery rack third position can be used to mount the recorder instead
• A Hyperdeck with SD card and PRO mount weighs approximately 1 pound 7 ounces, compared to a PowerCube which weighs approximately 1 pound 11 ounces

Depends on

• This modification requires removal of the internal battery, making external power necessary
• Internal battery removal eliminates the recorder's standalone operation capability
• The modification requires soldering directly to the motherboard, which presents a risk of damaging the device if performed improperly
• Specific instructions for recreating this modification in detail were not fully documented in the discussion
