[carl_rcbuggy]

hello everyone i have 2 trackpower 3200 lipos 1 of them wont balance well it wont even charge if i have the balance lead pluged in i have a bc6 bantom charger with the track power balancer lead. 1 Lipo is working perfect but the other one wont it keeps coming up this error on the charger (battery vol err cell connect) witch means there is a bad connection at the individual connector . please check the connector and calbles carfully. i have checked and all looks fine its nothin to do with the charger because it works fine on my other battery. The lipo will charge if i dont have the balancer lead pluged in anyone no what it can be?

All the best carl
