The protection board is for 7 series li-ion 3.6V/3.7V batteries.
Stable various protective functions for charging and discharging, such as accurate overcharge protection, over-discharge protection, over current protection and short circuit protection.
It has aluminum sheet that would enhance heat dissipation for MOS tube, and extend the service life of MOS tube.
Batteries core hardware balanced processing, proper balanced current, reasonable balanced heat emitting, does not affect performance of battery pack.
Low quiescent power consumption, it can save energy.
