OptiMATE Lithium 8s LITHIUM series: 10-step 25.6V/26.4V 5A sealed battery saving charger & maintainer

Designed for LiFePO₄ batteries ranging from 2.5 Ah to 100 Ah, this unit delivers a 5 A Ampmatic-controlled charge, dynamically adjusting current based on battery size and condition. It supports low-voltage recovery from as little as 0.5 V and includes a comprehensive 10-step charging program: recovery, testing before charge, temperature check, ultra-low voltage assessment, cell save and test, damage test, cell balancing, optimization, post-charge testing, and continuous 24/7 float maintenance.

For advanced applications, the charger includes a "TUNE" mode that provides stable power—ideal for ECU programming, diagnostics, or vehicle display settings. It also features a "power support" function to maintain voltage during battery changes.

Built for durability, the charger operates reliably from –20 °C to +40 °C, is weatherproof (IP54), and draws less than 0.5 W in standby to save energy. Its robust enclosure includes wall-mount slots, a 1.8 m AC lead, and a 1.8 m DC output lead with SAE connector. Comprehensive electronic protection—against reverse polarity, spark, short circuits, and accidental disconnect—is included, along with a 3-year limited replacement warranty.
