Product Features:

• Meet the GEN5X1 - Similar to our GENM1, 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 one-bank onboard battery charger rated a 5-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.
