there was a video of a guy using a hobby knife to vent the cell and push the gas out. Then he sealed it with hot glue. I will never try that, lol. And yeah my confidence is low on these packs. I am running low on packs to try. Stock is very competitive here and i cant run crap packs. I tried and it sucked, lol. turnigy fade way too fast, promatch and protek use IP lipo cells and they puff like the ones in the pic. I am debating the new orion 4500 pack. But IMO Orion cells have always been over priced. plus, I would need to wire everything up for 4mm again. Not really hard.... but still. these high cap packs just puff because the cells fill up so much of the case. I have had SMC packs puff in the mail to me.
