Repairing, "venting" a soft case LiPo
I recently pricked a small hole with a hypodermic needle into one cell of a soft case 3s LiPo battery to eliminate some puffing. I pricked a tiny hole, some clear acid oozed out, I squeezed the cell a little more to get some more out, and then wiped it clean and dry. Then I put a small amount of ShoeGoo on the hole, tried to force some of the ShoeGoo inside with some finger pressure, and let it dry overnight. I think I succeded in sealing up the hole. I have cycled the pack 4 times since this (one day of use) and it seems OK.
By relieving the pressure in this manner, have I exdended the life of this pack? It is a 25C 2200mah 11.1v soft case flight pack. Has anyone else vented a pack in this manner and had good (or bad) results?
