Alright so today I went and ran my e-revo and surprisingly I didn't break anything major but I did break the traxxas wheelie bar and the rear bumper mount. I went to charge the packs and my charger is saying one battery is way out of balance how can I fix this? I have a really low grade charger, it doesn't have a discharge option or anything. Just an option to charge 1s,2s,3s.
