Some hard case lipos may have a little space between the case and the lipo cell.
Its possible that it could have bulged inside.
After two years its time for a new pack.
If you race its a good idea to buy a charger that gives you real time IR readings when charging or discharging.
This way you will know the performance of your lipos before you race.
If your competing at big races nothing beat new condition lipos.
