So i have a couple 3s lipos, ones a 3800 and the other a 4000. I charge and balance with the common sense rc ac-dc 6 charger. With one of the batteries it it works fine but on the other one when i start balancing the little timer will start but the amps and mah will just stay at 0..Does that mean the batteries going bad or is it just a glitch on the charger or something?
