The RB100-LT series 12V 100Ah lithium iron phosphate battery can charge at temperatures down to -20°C (-4°F). The system features proprietary technology which draws power from the charger itself, requiring no additional components.

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.

The RB100-LT battery meets UL, UN, CE and IEC certifications.
