Don't let dead batteries slow you down - our three-bank onboard battery charger maintainer has got you covered. Rated at 15-amps (5-amps per bank) for 12-volt batteries, this charger is versatile enough to handle marine, boat, starter, and deep-cycle batteries. With selectable charging modes including 12V, 12V AGM, 12V Lithium, and 12V Repair Mode, you can easily charge and control each battery bank independently. The integrated thermal sensor ensures precision charging by adjusting the charge based on ambient temperature, preventing over or under-charging. And with the ability to charge dead batteries as low as 1-volt, you'll never be stranded again. Features: Meet the GEN5X3 - Similar to our GENM3, only better. It's 37% smaller and delivers 43% more power. It's one of the best performing onboard marine battery chargers we have ever made. Multiple banks - A three-bank onboard battery charger rated a 15-amps - 5-amps per bank - for 12-volt batteries, including marine, boat, starter, and deep-cycle batteries. Charging modes - Independently charge and control each battery bank with selectable charging modes - including 12V, 12V AGM, 12V Lithium, and 12V Repair Mode - for all types of lead-acid and lithium-ion batteries. Enjoy precision charging - An integrated thermal sensor detects the ambient temperature and alters the charge to eliminate over-charging in hot climates and under-charging in cold climates. Charge dead batteries - Charges batteries as low as 1-volt. Or use the all-new force mode that allows you to take control and manually begin charging dead batteries down to zero volts. Redefined mounting - A simplified mounting system allows for quick and easy installations in any direction - even up-side-down - with an integrated anti-vibration backing to isolate shock, vibration, and noise. Designed for water - A fully-sealed and waterproof onboard battery charger with an ingress protection rating of IP68, but has survived brutal life cycle testing, including thousands of hours underwater.
