The E&J Lithium LiFePO4 battery which is a cold-weather performance lithium battery, it can safely charge and discharge at temperatures down to -20°C  (-4°F), also built-in active cell balancing system, extend the whole battery life and get the most out of the battery.

E&J Heated LiFePO4 batteries have a built-in heating system featuring proprietary technology that draws power from the charger itself.

Powered by an upgraded intelligent BMS with an active cell balancer, the battery will guarantee balance between each battery cell. our active balancing BMS system can move the energy from the high voltage cell to low voltage cell during charging and enable each cell which means the whole pack can be full charged each time. This can extend the whole battery life and get the most out of the battery.

The heating and active cell balancing system do not take power from the battery, but rather from the charger, ensuring the battery is not discharging itself. Simply plug the battery into the lithium charger and the internal heating and monitoring system take care of the rest.

Our heated lithium batteries are available in 12V, 24V, 36V and 48V. All of our 12V low-temperature lithium batteries can be connected in parallel up to 4 units.
