RELiON RB52-LT Lifepo4 Lithium Ion Battery (12V / 52Ah / Low Temp 4SC)

RELiON RB52-LT: Cold Weather Lithium Battery 12V 52Ah Deep Cycle RELiON RB52-LT is a 12V 52Ah lithium battery and is part of Low-Temperature Series. This compact and powerful lithium iron phosphate battery is specially designed for cold weather performance. The LT Series batteries can safely charge at temperatures down to -20C (-4F) using a standard charger. The system features proprietary technology which draws power from the charger itself, uniformly heating the cells within the battery to 41F (5C), 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 -20C using a standard charger. The RB52-LT is a perfect choice for use in off-grid solar, remote monitoring, and in any application where charging in colder temperatures is necessary.
