New in August last year
(18/08/11, still have receipt) and probably had no more than 10 charges on them. Have some Intelect saddles with similar usage of the same age but no signs of damage. Non of my 1s cells have done this.
Have read stories of manufacturers increasing capacity but to keep the case within the regs they have to thin the battery case, hence some of the puffing we might be seeing with our LiPo's.
Got them out with a view to using them in a GT12.
