Basically are my lipos past their best, What sort of % should be in packs after running them. I was told not to have to put more than 80% back in them to fully charge them, Is that figure correct. As on my 3s 2200mah i have to put around 2000mah in now which is 90%. Thay have had quite a lot of use & charging over the last 5-6 months & i do run them quite hard with the set up ive got. They also take around 63 minuets to fully charge. Thanks Martin.
