First off Ive used Lipos for a few years so not new to them. Ive had a orion Carbon 3200 swell up for over draw from a 7700 motor before and it went back down after awhile. Orion was great and exchanged it.

My son has a Platinum 4800 Orion lipo he has used about 2 years or so. Recently I noticed it has swelled up between 1/8-1/4" on 1 end only. Its the end opposite the connectors. Enough it popped the seam on the case and cracked the end of it. Soon as I noticed it I took it out of his buggy and took the wires out of it. Its sat for some time and never went back to normal. Not sure when it happened, he ran it a few weeks ago no issue before I noticed it.

Is there a way to tell if its safe to use still or should i just salt water it and pitch it? We have gotten our money out of it but hate to pitch it if I dont need to.

Not blaming orion...just put their name in case it would help someone tell me why it happened...nothing but good things for orion from me.
