The auto self-heating function will be activated by the BMS when the battery is connected to a charger at -20℃ to 5℃ (-4℉ to 41℉). The heating will stop when the battery temperature reaches 10℃ (-4℉).
These two series primarily address the charging issues of LiFePO4 lithium batteries in cold weather. The main difference between the Low-Temperature series and the Self-Heating series lies in the presence of an automatic Battery Management System (BMS) heating module. The Self-Heating series allows the battery to self-warm without any action required from the user while charging.
However, the Low-Temperature Protection series will automatically cut-off the charging when the temperature is below 0℃ (32℉), and it requires you to take some measures, such as placing the battery in a warm indoor environment, to warm it up to 5℃ (41℉) and restore charging capability.

No, the heating system uses a small amount of power from the charger and does not significantly affect battery capacity. It efficiently warms up the battery before charging.
No. The charging will start after the lithium battery heats itself to 10℃ (50℉).
External heating only heats the casing and does not heat the battery cells. In conditions of -20°C, after external heating for two hours, the battery cells temperature rise to 5°C, but the lead-acid casing temperature has risen to 70-80°C.
Therefore, it is not recommended to externally heat the battery, as the actual cell temperature cannot be determined at this time.
Yes! Self-heating batteries function like regular lithium batteries in warm conditions. The heating feature only activates in cold temperatures, so it won’t affect performance in warm climates.
Self-heating lithium batteries are ideal for:
- RVs and campers used in winter climates
- Off-grid solar systems in cold regions
- Marine applications, such as boats operating in icy waters
- Outdoor equipment exposed to freezing temperatures
We recommend using a LiTime lithium-compatible charger for the best performance and longevity.

LiTime self-heating lithium batteries include a 5-year warranty and lifetime customer support.
