OptiMate Lithium 4s 0.8A Quad Bank LITHIUM series: 8-step 12.8V 0.8A sealed battery saving charger & maintainer x4

Each independent charging bank supplies 0.8 A constant current and runs a specialized 8-step automated LiFePO₄ program: low-voltage recovery, testing, bulk charging, balance pulses, optimization, post-charge testing, and continuous maintenance. It revives deeply discharged packs from as low as 0.5 V and includes a BMS wake/reset sequence for battery-protected systems. Built-in diagnostics monitor battery state of health and alert to potential damage.

The charger is energy-efficient (<0.5 W standby), fully weatherproof (IP54), and rated for indoor/outdoor use from –40 °C to +40 °C. It features spark suppression, reverse-polarity and short-circuit protection, and automatic shut-off to ensure safety even during unattended operation.
