説明
Features:
<br>The protection board is for 7 series 18650 li-ion 3.6V/3.7V batteries.
<br>Stable various protective functions for charging and discharging, such as accurate overcharge protection, over-discharge protection, over current protection and short circuit protection.
<br>Batteries core hardware balanced processing, proper balanced current, reasonable balanced heat emitting, does not affect performance of battery pack.
<br>It has aluminum sheet that would enhance heat dissipation for MOS tube, and extend the service life of MOS tube.
<br>Low quiescent power consumption, it can save energy.
