Ok so my 2s Lipo was not charged for awhile, so i decide to try and charge it. My charger said the batteries were at a full charge and only lasted like 4 minutes in my qual then cut out. Today i decided to try and discharge them and try to charge them again. My charger said they were at 6.4v and I tried charging them back up and it went straight to 8.4v. Is this my charger or battery i am so confused.
