Was using two 2s (gens ace 5000mah) on my mugen eco, then I stopped for no particular reason and checked the voltage, one of the cells was at 5.08v !! and the other at 2.51v !!! WTH!! the other lipo was fine and the buggy didn't had any problems at all. I stopped using them just in case but now my charger says theres an overcharge error (2.51 and 5.08v). The lipos were balanced at 4.19 and 4.20 before using them and they didn't got hot or swelled.

Have no idea how did this happened
Any advice?
