Lipo feeling Numb

[qatmix]

Hi guys

My lipo used to run well for 4 races, however just recently it's started feeling really sluggish after two races. I assume after 2 years its startin to go off the boil. However when I charge it, it's only used 2000 ish of its 5800 capacity.

Any idea if its just dying, or can I cycle it or anything to give it a bit of life.

Oh additional info, it's always balanced charged although the last time it never actually balanced.. It just times out making micro little charges.

Cheers
