Package:1Pcs Board (Battery not included)
3S 4.2v li-ion lipo balancer board balancing board full battery balance board .
The balancing board is suitable for lithium-ion battery without balance functions, so as to equalize the charge of the lithium battery, the charging function, make the battery of each series of charging at the same time.
Parameter:
Voltage balance for each single cell: 4.2V
Balance current for each single cell :66mA
Size: L25mm-W22mm
The balancer is just an auxiliary function, balancing means when charging, with the same voltage.when one cell of each battery series needs to get 4.2V, other cells not the first cell voltage will perform to wait for other cells rising to the same level.
Note:
battery internal resistance differences within 5 milliohm, voltage within 0.03V voltage, power vary within 50mA
Power cuts according to the BMS parameter.
3S cnnection instruction:
B4 " No connection
B3 "Connect the battery positive;
B2" Connect the dot between battery 1 and battery 2;
B1 " Connect the dot between battery 2 and battery 3;
B - battery connection negative;
3S balance board can be used as 2S
Note: Balancing starts balancing when one cell get 4.2V, cut off voltage according to BMS parameter, but BMS cut off voltage needs more than 4.25V, which is much better.
4S connection Instruction:
Positive B4 + battery connection;
B3 + connect the point between 1 and battery 2;
B2 + connect the point between 2 and battery 3;
B1 + connect point between 3 and battery 4
B - battery connection negative;
4S balance board can be used as 3S,2S.
Notices:
1) this balance do not have charge and perform protection function, so it can't be instead of bms;
