The Lion Energy UT1300 Battery Warmer is a 12V heating accessory designed to help support cold-weather charging conditions for compatible Lion Energy UT1300 lithium battery systems. Lithium batteries generally need to be above freezing before charging, and this warmer helps maintain a safer battery temperature during cold-weather RV use, camping, off-grid storage, and seasonal auxiliary power setups. It operates from a 12VDC power source and is listed at 7.5W / 0.55A. The built-in thermostat turns on around 42°F and turns off around 68°F, helping regulate heating automatically. This listing is for the standalone battery warmer accessory and should not be confused with the Lion UT 1300 BT-H battery, which has an internal heater built into the battery itself.
The UT1300 Battery Warmer is designed to help compatible lithium batteries stay within a safer temperature range for charging in colder environments. It is useful for RVs, cabins, campers, trailers, solar storage setups, and off-grid power systems exposed to low temperatures.
The warmer operates on 12VDC and is rated at 7.5W / 0.55A. Its low power draw makes it a practical accessory for compatible auxiliary battery systems where cold-weather charging support is needed.
The thermostat turns the heater on at approximately 42°F and turns it off at approximately 68°F. This automatic on/off behavior helps reduce the need for manual temperature monitoring during cold-weather operation.
This product is intended as a standalone warmer accessory for compatible UT1300 battery systems. It is not a battery, charger, inverter, or solar controller, and it should be used only with compatible equipment and proper installation guidance.
The Lion Energy UT1300 Battery Warmer helps support lithium battery charging in colder conditions by adding controlled heat around a compatible battery setup. It is a practical add-on for RV, camper, cabin, solar, and off-grid power systems used in winter or shoulder-season conditions.
This is the external battery warmer accessory, not the UT 1300 BT-H heated battery. Confirm battery compatibility, placement, wiring, and installation requirements before using it with any lithium battery system.
