You can only set a battery charging voltage. Then the balancing circuit will attempt to discharge the high cells when they get close to the top, while the other cells continue to charge. So if you have cells with great differences in voltage (like in this case), you have to reduce the battery voltage, too.
Battery balancing works by redistributing charge among the cells in a battery pack to achieve a uniform state of charge. The process typically involves the following steps: Cell monitoring: The battery management system (BMS) continuously monitors the voltage and sometimes temperature of each cell in the pack.
Procedure Charge the new battery at a low current like 1A with the voltage set to 3.55V per cell. Using Pylontech software BatteryView is useful but not necessary, using Cerbo GX data can be used to monitor max and min battery cell voltage (it at least worked for my battery be it in a label reversed state).
A typical battery balancer consists of several key components: Cell voltage monitoring: Precision voltage measurement circuits for each cell. Balancing circuit: Either passive (resistors) or active (DC-DC converters, switched capacitors) components for charge redistribution.
The most difficult battery to balance took many days to balance. Procedure Charge the new battery at a low current like 1A with the voltage set to 3.55V per cell.
A low charging current will help because it gives the balancing circuit a chance to discharge that high cell at the same pace or faster. All cells will rise in voltage at a lower pace. Including the "high" cells.
