Dual Pro ProXtra I Onboard Charger

PX1 12 Volt Engine Battery to 12 Volt Auxilliary Battery

The Dual Pro ProXtra I Onboard Charger is a marine unit which takes engine alternator output from the starting battery, and passes it to an auxilliary 12 volt battery. The unit does not start the current flow until the starting battery reaches a factory preset voltage, and then monitors the starting battery, and shuts off current flow to the secondary battery, if the starting battery starts to lose voltage. When the auxilliary battery reaches a preset voltage, the unit shuts off.
