Description

RELiON LT Series Lithium Battery RB12 is a compact 12.8-volt, 12 amp hour lithium iron phosphate (LiFePO₄) deep cycle battery engineered for cold-weather charging performance. As part of RELiON’s Low-Temperature (LT) Series, this battery is designed to safely charge in temperatures as low as -20°C using a standard lithium charger, without requiring external heaters or additional components.

The RB12 uses proprietary internal heating and monitoring technology that draws power directly from the charger, automatically warming the cells before charging begins. This seamless, self-managed process ensures safe operation and reliable power delivery in cold environments. Its small footprint, lightweight ABS construction, and IP66-rated enclosure make it ideal for compact marine, RV, off-grid, and mobile power applications.
