| Not familiar with the charger. Voltage can tell you a bit about the pack health, but more importantly how much are you putting back in the pack? You should never discharge a battery below 20% capacity remaining. If your balancer/charger is cutting off, and the voltage is 12ish, you should be good. I don't know if that charger has a "amps put in" display on it. But for an example, if you have a 2000mAh battery, you should not put more than 1600mAh back in. Also, you should not discharge below about 3.0v/cell. This includes voltage drop under load. So if you pull it off your model and check the voltage, and it reads 9.0 on a 3s pack, you can be pretty sure you had a lower voltage under load. This can damage the packs. I had one pack that had a cell go bad on me and it read 4.0/4.0/1.2 for the individual cell voltages. It did this after a good charge and sitting on a shelf for 3 weeks. It had been in a pretty bad crash but didn't exhibit any other signs of damage. The only reason I found it was for no good reason I thought I would check voltages on the pack. Totally lucky. Had to trash the pack. |
