The NOCO GENIUS2X4 is a 6V and 12V four-bank smart battery charger, maintainer, trickle charger, and desulfator rated at 8 amps total (2 amps per bank). It charges and maintains four batteries at once, independently, making it ideal for fleets, dealerships, and owners of multiple vehicles such as cars, motorcycles, boats, ATVs, RVs, and lawn equipment. Each bank handles lead-acid and lithium-ion chemistries - flooded, gel, AGM, SLA, maintenance-free, and LiFePO4 - across a 40Ah capacity range. Fully automatic and safe for 24/7 connection with zero risk of overcharging, it uses an integrated thermal sensor and charges batteries from as low as 1 volt, with Force Mode for completely dead batteries. Compact high-frequency switch-mode design.
