SOC percentage scheduled charging

Why is it not possible to charge per 1 percent with scheduled charging? It go's in steps of 5% which causes some overvoltage issues with my BMS when it charges to 100%. 95% is a bit low, I would prefer to have the possibility to charge it to 99% if I want it to. Seems like a very simple change in the setting to apply

You can voltage cap in DVCC. That usually sorts that out.

When cells are unbalanced at 100% thats not really a solution because 7 cells undervoltage and 8 cells overvoltage are still together 51,4v

Longer absorption helps there. And your battery balancing system should sort it out.

The main issue is the cells are out of balance not the SOC percentage.
