Thanks guys for all the info. To be safe I discharged the battery and disposed of it since the first lipo i ever had go bad yet. Being cautious didn't want to try to recover it. I am using a lipo alarm and with setting to 3.7v i got around 6mins flight time. Not bad but i wasnt doing anything aggressive just LOS so i know that flight time could change. Now i have to get over the trembles. I get so nervous and play it safe hoping not to crash lol.

Thought i'd just add my 2 cents...

Got some tattu 1300's which probably spent quite some time on the store shelf. One out of 5 packs was bad on first flight (1 cell going below 3v, quad fell from sky), but after a long, slow balancing charge it was just as fine as the others.

Unless the battery puffs from over-discharge, there's a good chance it can recover.
