The GEN5X2 from NOCO is a Waterproof Battery On-Board Charger that is ideal for marine, boat, and deep-cycle battery charging applications. It requires an AC input voltage of 120 - 240 V, a charging current of 10 A, and a DC output power of up to 145 W. This one-bank on-board charger independently charges and controls each battery bank with selectable charging modes, including 12 V, 12 V AGM, 12 V Lithium, and 12 V repair mode for all types of lead-acid and lithium-ion batteries. It includes an integrated thermal sensor that detects the ambient temperature and alters the charge to eliminate over-charging in hot climates and under-charging in cold climates. This onboard charger automatically detects battery sulfation and acid stratification to restore lost battery performance for stronger engine starts and extended battery life. It charges batteries as low as 1 V and also allows the use of the all-new force mode to manually begin charging dead batteries down to zero volts.

This IP68-certified fully sealed onboard charger acts as a trickle charger as well as a battery maintainer and offers a 24/7 fully automatic, worry-free battery charger for everyday use with zero over-charges. It offers a simplified mounting system that allows for quick and easy installations in any direction with an integrated anti-vibration backing to isolate shock, vibration, and noise. This charger has undergone brutal life cycle testing, including thousands of hours underwater. It is available as a module that measures 163 x 119 x 53 mm.
