Pete had a brand new LiPo that had a completed knackered cell, we all use the little lipo checkers that you plug into the balance lead so we always know where are on cell voltages etc. The one pete had was checked before putting on the charger so new instantly NOT TO try and charge it else that would have ended up the same as what happened last night.
If you dont have one already this is a very handy piece of kit. I always check before and after it goes in the car and before and after I charge it so I always know the health of my lipos before moving current through it.
