OptiMATE Lithium 4S 0.8A quad-bank charger designed for up to 4 x 12.8V/13.2V LiFePO4 / LFP batteries. This unit will automatically charge, test and maintain up to four 12.8V/13.2V LiFePO4/LFP starter or deep‑cycle batteries using a 4-Bank x 8-Step charging routine at 0.8A per bank. Its unique OptiMATE Lithium charging method can recover LFP batteries down to 0.5V. For batteries fitted with an internal BMS the charger provides an automatic wake‑up pulse so the battery is awakened on connection and charging commences. Continuous OptiMATE Lithium 24-7 smart interactive maintenance prevents discharge from connected circuitry, helping retain more usable charge and extending battery life.
