This high-capacity cold-weather lithium battery extends full-time RV and off-grid living to northern climates. The 12 volt 300 Ah capacity provides multi-day autonomous operation, while the LT Series design permits safe charging down to -20 degrees Celsius. Proprietary heating technology integrated into the battery warms cells during freezing-temperature charge cycles using only charger power—no additional equipment, wiring, or components required.

The seamless heating and charging process takes longer in sub-zero conditions as internal heaters prepare cells, but automatic monitoring ensures safe operation without user intervention. Once charged, the battery delivers the same reliable, consistent voltage output and extended cycle life as RELiON’s standard lithium offerings. LiFePO4 chemistry provides zero maintenance and superior performance compared to lead-acid alternatives. Ideal for year-round remote living, cold-climate RV travel, and industrial applications in demanding environments.
