yer..i read that too.
i had a 3s align 2200 heli lipo with a low cell...i took off the low cell and used the remaining 2s for my t8fg.

i put the low cell in fresh water for 2 days and it was still charged...so i stabbed it loads of times and put it back in for another 2 days...still charged .

in the end i had some fun by shorting it out, it still had enough charge to spark and make the tabs glow ....disclaimer....dont do it...it can be dangerous and cause burns......but its fun
