The Gen 4 battery hanger comes wired with the top and center battery positions already in parallel, with only two connector pairs leading to the jumper block, which limits circuit separation options.
Accessories are always powered by the camera battery regardless of base or jumper block configuration, while only the monitor can be powered from a separate circuit.
The auxiliary battery provides 24 volts when wired in series.
Custom jumper blocks can be built to utilize all three battery positions in parallel for 12 volt operation, allowing flexible battery placement for weight distribution without requiring the 24 volt series configuration.
Some technicians offer modification services that include adding a bladed heat sink to the jumper block for temperature management.

The discussion does not specify which Gen 4 models are compatible with these modifications.
No technical details are provided about how to implement the three-battery parallel configuration yourself.
The heat sink modification and its effectiveness are mentioned anecdotally but not thoroughly tested or documented.
Specific compatibility with different camera and monitor models is not addressed.
