Product Details
The GenPro10X4 is a compact and powerful onboard marine battery charger, measuring 10% smaller than its predecessor while delivering 33% more power. It is a one-bank charger rated at 40 amps (10 amps per bank) designed for 12-volt batteries, suitable for marine, boat, starter, and deep-cycle batteries. The charger features selectable charging modes, allowing independent charging and control of each battery bank, including modes for 12V, 12V AGM, 12V Lithium, and 12V repair, accommodating various lead-acid and lithium-ion battery types. The integrated thermal sensor adjusts the charging to prevent over-charging in hot conditions and under-charging in cold weather. This unit can charge batteries as low as 1 volt, and features a unique Force mode to manually initiate charging for dead batteries down to zero volts. It automatically detects battery sulfation and acid stratification to restore lost performance, enhancing engine starts and prolonging battery life. As a fully-automatic battery maintainer, it ensures continuous use without the risk of overcharge. The mounting system is simplified for quick installations in any orientation, including upside-down, and it features anti-vibration backing to reduce shock, vibration, and noise. The charger is fully sealed and waterproof, making it ideal for marine environments.
