Take advantage of the latest in battery technology.

The RELiON RB300-LT is a 12V 300Ah lithium ion phosphate battery and is part of RELiON’s Low-Temperature Series.. This lithium ion phosphate battery is specially designed for cold weather performance. RELiON’s LT Series batteries can safely charge at temperatures down to -20°C (-4°F) using a standard charger. The system features proprietary technology which draws power from the charger itself, uniformly heating the cells within the battery to 5°C (41°F), so that it can be charged at its full recommended current. LT batteries require no additional components such as heating blankets.

The entire process of heating and charging with the LT Series is completely seamless. Simply plug the battery into the regular lithium charger and the internal heating and monitoring system takes care of the rest. Because it takes time to heat the cells, the charging process in below-freezing temperatures could take a little longer. Chilly nights off the grid are now easier with the RB300-LT and perfect for RV’s, Sprinters, Class A and Class C vehicles, and more!
