This compact power management unit is perfect for managing all the power on your aircraft. If you have an alternator on your gas engine, you can connect it to this unit and it will provide stable DC power and keep your battery charged up. If your alternator is not producing power, this unit will supply your aircraft with power from the battery that you connected.
