The Expion360 DC to DC mobile charger is designed to rapidly and safely charge Lithium Iron Phosphate (LiFePO4/LFP) chemistry deep cycle batteries from the vehicle alternator through the starting battery.

This mobile charger is unique in that it uses a 2-stage constant current (CC) constant voltage (CV) charge profile with 14.6 volts at 25 amps. The charger is compact, easy to install, and simple to use. The mobile charger is specifically designed to charge the Expion360 VPR 4Ever Classic and Platinum batteries. It can also be used with other LFP chemistry batteries that recommend the same charge profile.
