What is a BMS? What does it do and where is it located?

A.
BMS is short for Battery Management System. It’s like a bridge between battery and users. The BMS protects the cells from getting damaged — most commonly from over or under-voltage, over current, high temperature or external short-circuiting. The BMS will shut off the battery to protect the cells from unsafe operating conditions.
Q.
How safe are Lithium-Ion Batteries?

A.
Our LiFePO4 batteries are considered to be safe, non-flammable and non-hazardous for superior chemical and mechanical structure.

They can also withstand harsh conditions, be it freezing cold, scorching heat or rough terrain. When subjected to hazardous events, such as collision or short-circuiting, they won’t explode or catch fire, significantly reducing any chance of harm. If you’re selecting a lithium battery and anticipate use in hazardous or unstable environments, LiFePO4 battery is likely be your best choice. It’s also worth mentioning that they are non-toxic, non-contaminating and contain no rare earth metals, making them environmentally conscious.

What ’more, it can be applied in energy storage solutions in your home or power your truck air-conditioning.

Charging ◢

Q.
Can lithium ion batteries be charged anytime?
