Balance voltage for each single cell: 4.2V; Balance current for each single cell: 66mA High quality: high accuracy, fine workmanship, durable, and long effective life The balance board is suitable for the lithium battery without balanced charge The balance board has the function of equalizing charge, make the battery pack each series charge fully at the same time When one cell voltage get 4.2V, the other cells not, the first cell voltage will discharge to wait the other cells rising to the same level Basic parameters
Equalizing voltage: 4.2V
Equalizing current: 66mA
Product size: 26 * 20.5 * 2.4mm

Solder joint description:
B-: Connects to the negative terminal of the battery string
B1: Connect the contact between battery 1 and battery 2
B2: Connect the contact between battery 2 and battery 3
B3: Connects to the contact between battery 3 and battery 4
B4: Connect to the positive battery string terminal

Note:
This equalizing board is applicable to lithium battery pack without equalizing charge. The equalizing charge enables all batteries in the battery pack to be fully charged at the same time.
This equalizing plate has no charge and discharge protection function, and cannot replace the protection plate. When the battery is charged, the first fully charged battery is discharged through resistance to equalize the shunt.
