This advanced battery combines long cycle life, lightweight design, and enhanced safety, making it ideal for RVs, solar systems, marine use, and off-grid applications in harsh climates.
How Does a 12V 100Ah LiFePO4 Battery with Self-Heating Work?
This battery integrates lithium iron phosphate cells with an internal heating system that activates when temperatures drop below a preset threshold (usually around 41°F or 5°C). The self-heating pads raise the battery’s internal temperature, allowing it to safely charge and discharge in freezing conditions. Once the battery reaches a safe temperature (around 50°F or 10°C), the heater automatically turns off. This technology protects the battery from damage caused by charging at low temperatures and ensures optimal performance year-round.
