7S BMS board with heat sink case. If you are making a e cycle battery with lithium ion battery then you need this bms board to protect your battery from over charge protection, Low discharge protection and for battery good life. This bms board used in 18650 lithium ion battery model and can hold max 20A current. Remember 20A cuurent does not mean 20AH. 20A means for max 588 watts motor.
