Even if to bring the single cell back to life with the pb charger trick I would say it will fail again if not hold its charge at all

I ressurected two of my new 4S 2200`s after running them too low because of an inaccurate current sensor was telling me I was fine :(

They came back from the dead, but even though they were holding the voltage per cell after a charge, my flight times were dismal. Paul put them on his expensive tester and they were both epic fails :( It happens and it sucks
