Charge-on-the-fly: After the boat’s alternator has fully charged the starting battery, this technology will reroute the alternator power to the trolling motor batteries
Battery Protection: extends battery life by protecting your battery from frequent deep discharges
LED Indicator Lights: Inform of charge stage, maintenance mode status, error notifications and full charge
Waterproof Construction: All on-board chargers are built to be waterproof, shock-resistant and vibration-resistant
3-Year Warranty: All battery chargers come with a full 3-year replacement warranty
Supported Battery Types: 12v AGM, 12v Flooded Lead Acid
