sorry sir i dont know what in the pic your attach..Could be a too low voltage?
Could you test the voltage at all outputs; 4 mesures.
my battery use for Q500 sir.. i have imax b6 charger to, but i try it still cannot charge..If you have a classic Lipo charger, try charging with the 2 external plugs 4S and about 5A charge current.
Yes, your battery seem to be not in good state but that could be the charger fault.
After that, you could try this:
Typhoon H battery connector
And also, take a look here:
Battery adapter for the Typhoon-H on the way
Its a common mistake with newcomers to the hobby you never want to let the battery drop below 3.5 volts per cell under load @ 10.6 volts you should be landing, this will prolong the longevity of your battery's and protect them from permanent damage.its
sorry sir i dont know what in the pic your attach..
my 1st battery show 10.6V (1=3.7, 2 = 3.7, 3=3.2)
my 2nd battery show 9.39V (1=3.4, 2 =2.95 , 3 = 3.0 )
seen like my battery death.
im newbie on this things..
Glad it worked out for you just remember you cant always bring them back to working condition, it pays not to discharge them to low, there are loads of youtube video's to give guidance particularly to newcomers to the hobby regarding looking after your lipo batterys for longevity and understanding of the battery workings.All solve.. recovery back my battery.. thanks all
