Drawing power from the boat's alternator, our new on-board DC chargers can charge up to three trolling batteries when the main engine is running. Inconspicuous but powerful, it features a discreet profile, turns off when the engine is not in use, and has an output of up to 20 amps. Available in one, two, and three-bank models.
