Hi!
I just buy an new 3 cells, 11.1V, 3900 mAh LIPo battery, and a balance charger for 2 o 3 cells Lipoz batt.
So I connect the charger and start charging the battery. All the light have a normal signal (red light ON, green light blink).
For now have passed 5 hours... And still the battery isn't charged (the green light blink - must stop blink when charged)

Is this normal???

This is my battery:

If the charger is really a 750 ma then 750 x 5hrs = 3750 mah battery?

Lipo's can be charged at 1C.....that means 1 times its caapcity.You have a 3900mah pack which is 3.9 amps.This battery if charged at 3.9 amps would take about an hour to charge if completely dead.You have a charger that only charges at 750mah....thats .75 amps,3/4 of a amp.So,yes with a 750mah charges I can see it taking 5hrs to charge your pack,as you are only chargeing it at 1/5th its C

Ok, thanks!
Yesterday I disconnect it when was charging after 5 hours, but I will charge it again to see how much will go until will charge it completely.

If you have a voltmeter, to verify whether is full charged it should read 12.6 volts

Ok, I leave to charge the battery and it take 7 hours...

It's just that the charger is not so fast (about 500mA - I think???), and the battery have 3900 mAh, so it take something more that 7 hours to full charge.


Anyway, thanks everybody!
