How does the heating element work?

---

The battery management system monitors the internal temperature of the battery. If the temperature drops below 32°F (0°C) and a charge cycle is initiated the BMS will divert charge current to the heating element until the uniform internal temperature of the battery is safe for charging. The specific safe charging temperature differs. For small batteries it's 50°F (10°C), for larger batteries its 41°F (5°C). See individual data sheets for details.
