4 series 14.8V18650 lithium battery equalization plate ,4S16.8V, polymer battery equalization plate
4.2V balanced voltage, the equilibrium current is 66mA
Equilibrium voltage and equilibrium current
Matters needing attention：
The equalization board is applied to the lithium battery pack without balance charging, and the charging equalization makes the batteries in each battery pack full of electricity at the same time.
The balance sheet has no charge and discharge protection function, and can not replace the protective plate. When the battery is charged, the battery which is full of electricity is discharged by resistance, so that the shunt is balanced.
