Default How did you know the condition of your LIPO pack?

By checking the internal resistance per cell?
e.g. 5-10m ohm for new cell
11-25m ohm for used cell
over 30m ohm needs to replace, not sutiable for play anymore.....

I would say that.the IR is a good indicator if you know what your pack was new... My packs IR vary between 1-3, but a thunderpower is much higher.

Also the pack balance AFTER a run would be a good indicator of cells falling off.
