The voltage of one of my batteries - the top one in the rightmost column of the OLED - drops significantly faster than the rest of the batteries.
As I type this it is 3.0 while six of the batteries are at 3.2 and one at 3.1 (battery capacity is 81%).
My knowledge here is very limited. How should I interpret the voltage numbers?
Is this battery simply of worse quality than the others or are the batteries somehow unevenly discharged?
