Internal Heating Version

Lithium batteries, especially LiFePO4 (lithium iron phosphate) batteries, perform better in cold weather than lead-acid batteries.

Better Cold Cranking Power: Unlike lead-acid, lithium batteries can still deliver power efficiently in cold temperatures.
Faster Recharge: Lithium batteries charge more efficiently, even in cool conditions, compared to lead-acid.
Lighter Weight: Less strain on vehicles and equipment in winter conditions.
Longer Lifespan: They last significantly longer than lead-acid batteries, even when used in winter.

Challenges & Solutions:
Cold Charging Issue: Lithium batteries can’t charge safely below 32°F (0°C). However, models with self-heating technology (like Enjoybot’s) automatically warm up before charging.
Discharge Efficiency: While lithium batteries can still discharge in cold weather, extreme cold (-4°F / -20°C or lower) can reduce performance. Some high-quality LiFePO4 batteries include low-temperature protection to prevent damage.

A self-heating lithium battery can be beneficial if you plan to charge your battery in cold environments. The self-heating feature ensures that the battery will charge properly in temperatures as low as 32°F (0°C). If you live in a region with cold winters or expect to use your battery in freezing conditions, a self-heating battery may be what you are looking for.

When the temperature drops below 32°F (0°C), charging is automatically suspended, and the built-in heating pad activates to warm the battery. At this time, the charger powers only the heating pad, ensuring safe operation. Once the temperature reaches 41°F (5°C), heating stops, and charging resumes, ensuring optimal battery performance in cold conditions.

These two features address the challenge of charging LiFePO4 lithium batteries in cold weather. Low temperature protection automatically shuts off charging when the temperature drops below 32°F (0°C). To resume charging, simply place the battery in a warmer environment, and charging will be restored once the temperature rises to 41°F (5°C). Self-heating enables charging at low temperatures by activating the heating mode when the temperature falls below 32°F (0°C). Charging will resume automatically once the battery reaches an optimal temperature.
