Building a custom second battery hanger for cinema power distribution with cross-charge prevention

13 years old. Gear and prices may have changed since.

What the thread found

  • A parallel-wired battery configuration requires a diode to prevent cross-charging between batteries
  • The diode should be wired at either the positive or negative terminal of the second battery plate
  • The factory Zephyr system delivers 12 volts on standard LEMO pins while offering 24 volts on a third pin, allowing backward compatibility with 12-volt accessories
  • A Schottky barrier rectifier with dual cathodes can serve as a suitable component for preventing parallel battery cross-charge in this application

Depends on

  • The specific diode model mentioned was identified through forum discussion rather than official manufacturer documentation
  • Implementation details for integrating the diode into the factory plate were not confirmed
  • Testing was limited to one builder's specific setup
