RELiON RB300-LT: Cold Weather Lithium Battery 12V 300Ah Deep Cycle
The RB300-LT is a 12V 300Ah lithium iron phosphate battery and is part of RELiON’s Low-Temperature Series. This lithium iron phosphate battery is specially designed for cold weather performance. The 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 41°F (5°C), 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.
The Low-Temperature Series battery has the same size and performance as other RELiON batteries but can safely charge when temperatures drop as low as -20°C using a standard charger. Chilly nights off-the-grid are now easier with the RB300-LT – perfect for RVs, Sprinters, Class A vehicles, Class C vehicles and more!
