I'm using these batteries on my Ebike now. I wanted to know about safe these really are. So I sacrificied the 2s 5000mah Acepow and charged it in parallel with a 4s pack. The 2s pack didn't even puff up. No drama whatsoever. The cells are dead now, but I feel safer running these batteries.

Update:
I cracked the pack open and the cells were a bit puffy, but not enough to crack the pack open by itself. On further inspection, I noticed the copper traces on the pcb board where blown. Soldered them back together and the pack is good as new. Well sortof.
