With a low-profile enclosure and a waterproof, corrosion-resistant design, our DC Alternator Chargers use current from your boat’s alternator to re-charge trolling batteries when the main engine is running. Then, the charger turns off while the engine isn’t in use. Experience effortless, accurate charging with up to 30 amps of total output.
