Status: offline 		I have a Lipo 6000mah 7.4v 2s2p and it wouldn't finish balancing after an hour of trying to balance it. I know the longer it takes batteries to balance, the worse off they are. The thing used to balance in seconds. The issue I'm having is that I didn't use the battery for about 6 months, so I never got to see it gradually take longer for it to balance, I just saw one huge gap. Anyhow, I wasn't sure if my battery was toast or whether I should just let it continue to balance. Please let me know what you guys think. Thanks.

Status: offline 		If you left it sitting for six months with out use and depending on how it was stored the pack may have a bad cell. Li-Po's should be stored at half their capacity and cycled at least once a month.

Status: offline 		Is there any way I can check to see if it has a bad cell or not? I left it sitting with 7.6volts total charge left on it. Also, I had another of the exact same battery with the exact same amount of runs on it left with 7.6volts on it and it balanced quickly and ran just fine...

Status: offline 		Check the voltage of the pack. If it isn't fully charged, charge it. If you can use a balancer while you charge. Once it's fully charged put on the balancer and let it go to work until it is fininshed. What type of Balancer do you have?

Status: offline 		i have the TP-205v balancer. I charged the pack up to 8.4volts with the balancer plugged in to the battery pack and into my TP-1010c charger. Once it got to 8.4 volts, the balancer was still indicating the pack wasn't balanced yet, so I took it off the charger and let it continue to balance. After about an hour, I unplugged the balancer thinking the battery had a problem. That was when I charged my other battery that I left sitting for the same time, with the same voltage and that one charged/balanced/ran perfectly still.

Status: offline 		Take a voltmeter and check the voltage of the cells at the balance tap. First red wire and first black wire will be cell bank 1 then move to the first black wire (As +) and the last black wire (As -) that is cell bank 2 . Give me those voltages. If your pack is still out of balance leave the balancer on until it finishes. If a pack is that far out it may take a while. Also some balancers will be so sensitive that they cells may be right next to each other but off .01 and the balancer might be fighting that. The LBA-10 will do this sometimes. Check the cell voltages when the pack is fully charged and give me those numbers.
