Self Heating LiFePO4 Lithium Battery Pack FAQ

Can you make 48V self heating lifepo4 battery series?

Sure, our 12V and 24V lifepo4 batteries are connected in series and parallel to the 48V battery series.

Does your self heating lifepo4 battery be waterproof ?

We can design the self-heating lifepo4 battery as a waterproof IP65 or even IP68.

Is your self heating lifepo4 battery dangerous when it is charged below 0°C?

No, the standard battery will be fired or exploded during the temperature below 0°C. But CMB’s self-heating battery charge below 0°C is reliable.

What is your MOQ for self heating lithium battery?

The MOQ is 1 piece but we only provide the self-heating lithium battery for commercial use not for private use.
