Lipo repair

[Jahay]

im bringing this post back from the dead....

Linc... i need some lipo help/advice. I do not have pictures of the lipo yet but hopefully you can just confirm the problem and then advice the course of action i should take once i get pictures up?

I have a hyperion G3 6500mah 35c 3s lipo.

Firstly i will say that my electrics are fine as the truck runs nicely with my other lipos... problems occur only with this lipo.

How it started:
Had a few bad landings with my truck one day... the next day, i plugged my lipo into the ESC, i got the beeps and was about to move. But then upon accelerating, the truck would stutter terribly. If i lifted the truck off the ground, and slowly acclerated then the wheels would spin just about... once the truck is back on the ground. I get problems.

i never had a problem with charging the lipo even when it was in this state.

So i then thought that the lipo probably had a solder break or a bad connection somewhere, possibly from a bad landing etc...

Now the lipo does not charge and reads error when charging, and i get no stuttering at all when i connect it as it doesnt even turn the esc on.

When i took all th shrink wrap off the motor, i could not see any obvious signs of solder breaks or anything? i will take pics and post them this evening, but i am wondering how you would approach the lipo in terms of fixing it?

Thanks a lot... hopefully you can help me out

edit...
This is how my motor behaves on this lipo. It sounds like it is cogging...
