RB100-LT: Cold Weather Lithium Battery

12V 100Ah Lithium Deep Cycle Battery

The RB100-LT is a 12V 100Ah lithium battery and is part of RELiON’s Low-Temperature Series. This lithium iron 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, requiring no additional components. Now improved protection with an IP67 ingress protection rating, which completely repels dust and resists water ingress for up to 30 minutes submerged at 1 meter.

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. The RB100-LT is an ideal choice for use in RVs, off-grid solar, electric vehicles, and in any application where charging in colder temperatures is necessary.
