Hello, Hate to barge in here, but seems like a good spot to ask my question about a Lipo issue as well.
I have 3 2s lipos I use with my SC truck, one is stock at 30c 3500maH and the other two are 30c 5200 maH. I have been charging the batteries using a B680AC charger set properly for each battery and seemed to develop a problem. the stock battery and one of the 5200 batteries work and charge just fine (balance charge set to each battery needs) but the other 5200 battery doesnt seem to charge properly or even turn my truck on, I get a quick flash on the esc and thats it. Any ideas?
