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

The OptiMate Lithium 4s 0.8A is a fully automatic charger and maintainer specifically designed for 12.8V–13.2V lithium iron phosphate (LiFePO₄) 4-cell batteries. Ideal for motorcycles, ATVs, and other powersport vehicles, this compact unit ensures safe and effective charging, balancing, and long-term maintenance.

This advanced charger revives batteries from as low as 0.5V, activates battery management systems (BMS), and runs through a precise 8-step charging program. It features a 0.8A constant charge rate, ideal for battery capacities ranging from 2Ah to 30Ah. Once fully charged, the charger enters a smart maintenance mode that alternates between charging and rest phases to preserve battery health without overcharging.

With built-in protections such as spark suppression, reverse polarity protection, and automatic shut-off, it ensures both user and battery safety. It’s globally compatible with a wide input voltage range and operates reliably in temperatures as low as –40°C. The weatherproof case, long cables, and included battery clips and ring terminals make installation easy and secure.
