What level of imbalance in series connected cells is good?
This is only my guess but when I charged a 12v pack of 9 lithium battery I would keep the battery different voltage around 0.01 to 0.15 or 0.2 max. If I see 0.3 different voltage I would get concerned But this is still my guess and I still

What is the voltage difference between cells of a battery pack?
Today we will share with you the voltage difference between the cells of a battery pack. Actually, the difference within a certain range is acceptable, usually within 0.05V for static voltage and within 0.1V for dynamic voltage. Static voltage is when a battery is resting, and dynamic is when a battery is in use.
How does voltage affect battery discharge performance?
Conversely, the larger the voltage difference, the less consistent the battery pack--and as a result, the discharge performance will be adversely affected. The discharge energy of the battery pack becomes insufficient, and it gradually deteriorates as the number of cycles increases.
What voltage difference could indicate that some cells are not as good?
What voltage difference could indicate that some cells are not as good as others? The first thing you should worry about the voltage of the cells: If one of them exceeds the max allowed (or recommended) charging voltage, which is usually 4.2V, then this cell will degrade more.
How many volts should a battery charge?
Two cells charge to 4.2V and one only cell charges to 4.15 or so. If after use, one cell is regularly 2.8 and the other 3.6, then the battery is damaged and needs to be replaced. Cells should never be discharged below 3.0v, preferably not even close to 3.0v
What is the nominal voltage of a final set of cells?
The nominal voltage of the final set of cells is the number of cells in series times the nominal voltage of a single cell. 1. Supplier Delivers Matched Cells If the cell manufacturer can deliver cells with a proven quality history of OCV within +/-0.02V then you will be able to assemble and charge these cells without gross balancing.
What is the difference between static voltage and dynamic voltage?
Actually, the difference within a certain range is acceptable, usually within 0.05V for static voltage and within 0.1V for dynamic voltage. Static voltage is when a battery is resting, and dynamic is when a battery is in use. For battery packs, the voltage difference between individual cells is one of the main indicators of consistency.
