A Leaf pack contains 192 cells, in 48 modules, each module is 2s2p (7.5V @ 65Ah). I am using 40 of 48 modules from one Leaf pack in the front. And I using 40 of 48 modules from one Leaf pack in the back.
To first answer your main question, the module will balance the battery if you. Charge it until it stops charging as described above. Discharge the battery ''somewhat'' until the most charged cell''s voltage drops below 4.2V. Now, charge the battery at a current lower than the rated balance current - in this case about 60 mA.
A battery pack is composed of many battery cells linked together. A battery pack is out of balance when any property or state of those cells differs. Imbalanced cells lock away otherwise usable energy and increase battery degradation. Batteries that are out of balance cannot be fully charged or fully discharged, and the imbalance causes cells ...

I tried to use this module for a 4S 18650 battery pack: Beside charge controlling it is supposed to balance cells and this is where my issue emerges. If I put some unevenly charged cells in the pack, lets say 3 cells at 3 V and one at 4 V, and connect it to a 16.8 V power supply with current limited to max 500 mA.

When a battery pack is placed into operation, different cells in the system can discharge at different rates. When this occurs, the SOC in the various cells will be different. Later, when the battery pack is to be recharged, the various cells might also recharge at different rates. The point of balancing is to redistribute charge from the ...

I have 2 identical 24v 2.7kwh battery packs, each have 60amp bms built in. And I am connecting them into series for 48v. They will be charged via mppt controller and for load there is 220v inverter which should never discharge completely batteries because of cut-off voltage on inverter is about 4 volts higher than on cut off on batteries.
The battery pack is at the heart of electric vehicles, and lithium-ion cells are preferred because of their high power density, long life, high energy density, and viability for usage in relatively high and low temperatures. Lithium-ion batteries are negatively affected by overvoltage, undervoltage, thermal runaway, and cell voltage imbalance. The …

of the first battery''s voltage, the battery pack often shortens the service time. As a result, there are leakage current requirements for the pins connected to the battery pack in Li-ion battery protection chip products [19–21]. In sum-mary, the leakage current will accelerate the imbalance between cells, which needs to be avoided.
I''m looking at rebuilding a Makita battery pack, and I''m 99% sure the chinese/ebay Makita "BMS" boards don''t do cell balancing ... Having squinted at it a bit, it''s built around these HY2213 "cell balancer" chips which only protect cells against overcharge by connecting a resistor across the cell when its voltage exceeds 4.200V.

The only pack that are out of balance use old cells and actually have a BMS with balance function. After inspecting the pack it turned out to have a heater cell and I assume that the cell drain was greater than what my BMS can balance (which is just a 100mA or something). From this I''d even argue that balance function would hide this and cause ...
