What is Lithium ion battery management system?

The protective circuit of a lithium-ion battery is designed to ensure that such overcharging and discharge conditions are safe and prevent deterioration of characteristics. The protective circuit of li-ion battery is composed of the protection IC and two power MOSFET, in which the protection IC monitors the battery voltage and switches to the power MOSFET mounted outside to protect the battery when there is overcharge and discharge state. The function of the protection IC is overcharge protection, overdischarge protection and overcurrent/short circuit protection.

Charging: 0 ℃ to + 50 ℃ (0 ℃ to 40 ℃ recommended)

Discharge: - 20 ℃ ~ + 70 ℃ ~ 20 ℃ and 40 ℃ recommended)

Storage temperature: 25 + / - 5 ℃ (recommended)

this is normal parameter for your reference, in our real application, sometimes we shall take good use with other temperature beyond the above temperature scope. so what should we do? 

it's a very good question, here writer is highly suggest you to put your troubles and questions to our professional sales engineer. he will feed you back with satisfing answer in a short time.

SINOLI shared a lot of articles with professional lithium ion batteries knowledge. hope that will help you indeed, if not, welcome to propose it out via email or telephone is fine.
