This low-temperature lithium battery extends operational capability into harsh winter climates. The 12 volt 20 Ah unit belongs to RELiON’s LT Series, engineered to accept charging at temperatures as low as -20 degrees Celsius. Unlike standard lithium batteries that cannot safely charge below freezing, this model incorporates proprietary heating technology that draws power directly from the charger—no extra components or modifications required.

The integrated heating system warms battery cells during the charge process, allowing a seamless workflow without manual intervention. Charge cycles do extend longer in sub-zero conditions due to the cell-warming phase. Once charged, the battery delivers the same compact, lightweight performance as RELiON’s standard LT offerings. Ideal for RVs, off-grid solar, electric vehicles, and equipment stored or operated in cold regions.
