Is this Lipo FUBAR?!?! 3S 4.17v - 1.17v - 4.20v....oh dear?!?!
« on: October 27, 2012, 09:46:09 PM »

My 3S lipo will not charge up at all and is giving the following voltage readings when trying to charge.

 4.17v - 1.17v - 4.20v

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
