Just bought a 3s gens ace 2200mah 60C lipo for my trex450pro v2. Got one flight out of it and plugged the balancing jack in to the balancing port on the charger backwards and ran my Thunder T6 charger on Storage as I do for other batteries. I cut it off manually when the voltage got near the proper storage voltage as I needed to go somewhere and did not want to leave it running while out of the house. I left it plugged in incorrectly overnight as I did not realize I made this careless mistake. I went to charge it this am and got the "low voltage" warning. Tested it with my voltmeter-- totally dead. I went to you tube and found some videos on how to bring back to life. Tried charging on NiMH setting to 9V to jump start it, but it did not work. The voltage only gets to about 6V, then the charger stops and shows "full". When I remove the battery from the charger and test again, it only reads about 1.7 volts, then goes to 0 after an hour or so. Also, during the NiMH charging, the charger charges for about 3 minutes (I am charging slowly) and the voltage builds, but then the voltage drops to 0 and starts recharging again, eventually getting up to 6 volts, then shutting off due to being full. It still shows the low voltage warning when I try to charge on lipo settings, of course.
I am thinking that one of the cells is bad and is not allowing the battery to charge to 9V (and then loses charge)
Can anyone verify that I just blew $37 plus shipping?
Is there any other way to bring this back to life? Thanks
