What is the cause of having one cell discharge more than the others? I use Protek 4s 20c 2100mah batteries, the battery in question is only 2 months old and has 15 flights of no longer than 6 minutes. Also I have never put more than 1400mah back into the battery after flying.

The Cells in a LiPo pack all have different cooling - the face cells have double the surface area exposed for cooling! The Temperature directly affects the cell performances.

Before you all go using heat-sinks and pc fans, LiPo cells have an operating temperature. About 50 degrees C is best. Above 60 and the performance starts to decrease again.
