I still can't believe MA or any other mfr would parallel cells like that. I know there are a few others, but the only truly safe way to work with that config is to charge it as a 4S and run it as 2S, but the balance tap is 2S....stupid!
Linc you should make a mattress out of all the puffy cells and make certain people sleep on said mattress- I'd pay to see it....
