4S 14.8V18650 Lithium battery balance board
4.2V balanced voltage, balanced current is 66mA
Balanced voltage and balanced current
The equalizer board is suitable for a lithium battery pack without a balanced charge, and the charge equalization causes all the batteries in the battery pack to be fully charged at the same time.
The equalizer sheet does not have a charge-discharge protection function and cannot replace the protective sheet. When the battery is charged, the battery that is fully charged is discharged through the resistor to balance the shunt.
