I wish this LiPo was 2 years old, it's only 3 months old

I would really hate to bin it, but if I consider opening the battery as an unsafe operation I think it's still the best option to safely get rid of it.
However, it might not be necessary to do so. I contacted Team Orion, and although they adviced against repairing it, the contact did admit it is possible. There is indeed a small PCB in there that burns if too big a current is drained from the battery, though it could potentially also be a melted solder joint.
I will probably have a go at opening it to check on the damage. If the PCB is burnt then I could try to get hold of a replacement one. If that isn't possible then soldering a piece of wire in place of the PCB is the only option.
All things considered, repairing this makes the battery more of a risk to use, so for serious racing I'll probably get a new pack anyway, just to be safe. I'll definetely get a battery again with a fuse/PCB in it to protect my other electronics, but it will probably have to be second hand. Is there anyone with a good condition Team Orion stick pack, 4000+mAh, 40+mAh that they can part with?
