LFP batteries are safe to use in temperatures ranging from -20°C to 60 °C / -4°F to 140°F, making them suitable for various weather conditions. This is especially beneficial for off-grid solar, RV, and trolling motor owners who may encounter extremely cold environments, providing consistent and reliable power.
Cold temperatures can negatively affect any battery's performance, particularly lead-acid batteries, which experience significant degradation in health and longevity in the cold. In contrast, lithium batteries perform much better in low temperatures.
LiTime offers self-heating lithium batteries, which automatically heat to an optimal charging or discharging temperature, ensuring safe operation in winter. Besides, you can also choose LiTime batteries with low-temp cut-off protection, which automatically disconnects and resumes charging to prevent damage and extend battery life in cold conditions.
With built-in 2 heating pads, LiTime self-heating batteries start heating at -4℉(-20℃) to 41℉(5℃) and stop heating at 50℉(10℃), when connected to a battery charger. Some of the heated models come with 2 heating modes: regular and energy-efficiency mode, further speeding up the charging efficiency, such as 12V 100Ah Group24 Omni, 16V 100Ah.
These two series focus on addressing the charging challenges of LiFePO4 lithium batteries in cold weather. The key difference between the Low-Temperature series and the Self-Heating series is the presence of 2 heating pads in the Self-Heating series. This allows the battery to warm itself during charging without any user intervention.
In contrast, the Low-Temperature Protection series will automatically stop charging when temperatures drop below 0°C (32°F). To resume charging, you'll need to take steps to warm the battery to at least 5°C (41°F) by placing it in a warmer indoor environment.

LiTime offers a 5-year warranty on our batteries. For more details, please visit our Warranty Policy.
Because LiFePO4 lithium batteries have different charging requirements than lead-acid batteries, we recommend using a LiFePO4 lithium battery charger.
Here are the charging options for LiTime lithium batteries:
1. AC-DC Lithium Battery Charger: Select a charger with the appropriate voltage to safely charge the battery.
2. Solar Panels: When using solar panels, always connect a solar charge controller to ensure safe charging.
3. Alternator/Generator:
