Details

This efficient and fast-charging 12V 40ah lithium battery is powerful yet compact enough to fit into many deep cycle applications. The RB40 is a lithium iron phosphate (LiFePO4) battery with more power, less weight, and up to 10x longer life than its lead-acid counterparts. Lithium is the logical choice for applications that will exhaust the batteries or run in extreme weather. RELiON lithium batteries provide more energy for high consumption than traditional lead-acid batteries. Lead-acid batteries also need to be maintained. If they are not maintained properly, their life span is shortened. Because lithium batteries require no active maintenance, a one-time purchase guarantees better lifetime value.

The RB40 is suitable in many outdoor and recreation applications where lighter weight and capacity are key. It's commonly used in the following applications: fishing electronics, robotics, solar lighting, remote power, outdoor adventures, and other deep cycle applications.

Not all lithium batteries are created equal. All RELiON Batteries use the safest and most stable components, including a LiFePO4 cathode and a built-in Battery Management System (BMS). The BMS ensures a long lifetime, safe handling - and high-accuracy State of Charge (SOC) calculations.
