Balanced cells

[hoober]

They can be any amount , as long as no one cell goes out of range. 3.5-4.2 volts.

It depends on the pack , the cell capacity match, and the level of charge and discharge.

An example would be a user who charges to 4.2 volts and discharges to 3.5 resting volts. The cells need to be perfectly matched in order to never go out of range. If at them bottom the pack had a cell that was .1 volts lower then the rest then the minimum for the (2s) pack would be 3.5 + 3.6 = 7.1 volts.
