How can you tell when a battery pack has gone bad?
I have 7-cell 3000 "powerizer" packs that came with the truck when we bought it used. We have a twin peak charger and all Deans connectors. Today my son was driving the truck with great speed, wheelies, etc. under mostly slow driving he got about 25 min run time. We put the bats on the charger, ate dinner and took the truck out again. The twin peak indicated that the bats were done and we re-peaked to be sure.
The truck would not even move. barely enough power to turn the tires when off the ground.
I recharged the batts again. for less than 10 min...both showed peaked. Truck then did wheelies and looked ok. Now has 3-4 min runtime!
back on the charger. one pack peaks in about 5 min, the other in 25+ min.
Is the one pack toast?
Thanks in advance for your input!
