OptiMATE Lithium LFP Select Lithium series: 10-step 12.8V 9.5A / 16V 7.5A battery-saving charger and maintainer

The OptiMate Lithium LFP Select is a professional-grade charger and maintainer for 12.8 V (4‑cell) and 16 V (5‑cell) LiFePO₄ batteries, ideal for performance vehicles, powersport gear, and high-end applications. With selectable output and powerful intelligent charging, it offers precision and reliability for batteries from 2.5 Ah to 120 Ah.

This advanced unit features a selectable voltage program—either 12.8–13.2 V at up to 9.5 A or 16 V at up to 7.5 A—with memory retention of your selection even if AC power is lost. The fully automatic 10‑step charging sequence includes low‑voltage start (from 0.5 V), pre-test, temperature check, cell save and testing, balancing, optimization, health testing, and continuous 24/7 maintenance.

Powered by Ampmatic current control and temperature compensation, it adapts charge rate and voltage to match battery size, condition, and ambient temperature. The unit includes a BMS wake/reset function to revive protected or deeply discharged packs. Rugged and weatherproof (IP54), it operates reliably between –40 °C and +40 °C with ultra-low standby draw (<0.5 W).
