hi, i have a 1s lipo, actually several. about 5 for my alias quad and 6 for another brand heli.
being all lipo charging cautions are the same, i have 2 batteries that appear to be a bit puffy.
their not really swollen but they spring back when you squeeze them a bit.
just like it would when you pinch the balls on bubble wrap.
should i throw these away!
I would defiantly not squeeze them haha

lipos do expand slightly during use. then they go back down when you charge them. hard case packs have extra room in the case so you dont notice it.
This will TOTALLY work, saw a guy on YouTube do it
