How To Protect Your Lithium Batteries?

Lithium battery (rechargeable) is required for protection, it is determined by its own characteristics. Because the lithium battery material itself determines that it cannot be overcharge, over discharge, short circuit and ultra high temperature, lithium battery charge and discharge, so the components always followed by a fine protection board and a current for the presence of insurance.

The protection function of lithium battery protection circuit board usually consists of PTC and current of the device work cooperatively, the protection board is composed of an electronic circuit, at -40 DEG to +85 DEG C under the environment of current monitoring time accurate electric core voltage and charge discharge circuit, to control the current loop off; prevent bad battery PTC the damage in high temperature environment.

Common lithium battery protection board usually includes control MOS, IC switches, resistors, capacitors and auxiliary devices FUSE, PTC, NTC, ID, memory, etc. The IC control, MOS control switch in all normal circumstances, the electric core and the outer circuit, and when the voltage or current loop exceeds the specified value, it immediately to control the MOS switch off protection, electric core security.

In order to better serve to our customers, we also provide you some high-quality protection board, and be evaluated as the most professional PCM supplier of electric tool batteries in 2014. 

Currently we always provide 1-26S PCM, the most current can reach 150A, and 80A is our popular type.
