Hello,
I'm currently trying to build a battery to power a drill, the configuration that I use is 6s3p. The problem that I ran into is that when powering the drill to above 70% power the battery starts to sag and 1 specific cell, the one in the middle of the first series pack from the negative terminal (the battery heats at the positive end). And after the cell heats the motor cuts the power.
How do I fix that? The same problem existed when I had the configuration 5s3p and even after I replaced the cell.
The battery is charged to 25v and the cells are pretty balanced.
I know I may have not explained the problem properly due to limited experience, but please feel free to ask any other details.
