Description:
This product is a battery protection BMS board which is designed for 7series lithium batteries. It can be used for ternary lithium batteries, manganese acid lithium batteries, cobalt acid lithium batteries and LiFePO4 batteries. And the board is equipped with multiple protective functions including overcharge protection, overdischarge protection, overcurrent protection and short circuit protection, so you can use it safely.

Features:
★The Protection Board adopts 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.
★Stable various protective functions for charging and discharging, such as accurate overcharge protection, over-discharge protection, over current protection and short circuit protection.
★24V 20A 7S lithium li-ion liFePO4 battery battery BMS protection board with low quiescent power consumption, it can save energy.
★The lithium battery protection board is for 7 series 18650 li-ion 3.6V/3.7V batteries.
