I had the same problem with a few packs I got from THS

heard that it's a batch problem....

Return the batts and ask for new one

for kokam...it's better to balance each cell periodically

Most lipo will balloon if its overdischarged. In your case, u must have had a very powerful flight for 7 min.

To use that battery for 7 min flight time, your avg current draw should not exceed 10 amps. Does your esc provide a lipo cutoff?

nope my esc is for brash motor.well just discard the thing. look like time bomb.
quite scaring.

sorry yap it provide cut off at low level.but i use sub c sanyo no problem at all and other brand lipo except kokam.well lost confidence in that product.
