OptiMATE Lithium 4s Lithium Series: 10-step 12.8V 10A sealed battery saving charger & maintainer

The OptiMate Lithium 4s 10A is a high-performance charger, tester, and maintainer designed specifically for 12.8V LiFePO₄ (4-cell) lithium batteries. Ideal for high-capacity batteries in powersports, automotive, and light commercial vehicles, it delivers intelligent, fully automatic charging that maximizes performance and extends battery life.

With a powerful 10A output, this charger supports batteries from 5Ah to 200Ah and recovers deeply discharged batteries from as low as 0.5V. Its 10-step charging program includes essential functions like soft start, battery analysis, low-voltage save mode, fast bulk charge, cell balancing, optimization, and long-term maintenance.

The OptiMate Lithium 4s 10A uses advanced Ampmatic technology, automatically adjusting the charge rate based on the battery's size and condition. It includes temperature compensation to ensure safe and effective charging across a wide temperature range. For batteries with built-in Battery Management Systems (BMS), the charger offers an automatic reset function, ensuring compatibility with modern lithium packs.

Its durable, weatherproof design (IP54 rated) makes it suitable for workshop or outdoor use, and it supports global AC input from 100-240V. The low standby draw of less than 0.5W enhances energy efficiency.
