My 6 cells are peaking at 9volts. Is that ok or normal? I'm using an AC/DC Intellipeak charger and 2 different Duratrax batteries. One is 3800mah the other 4200mah.
Yes, that's normal during charging. I have a 6 cell pack that regularly peaks around 9.2V while charging. As soon as the charge stops it comes back down to about 8.5V.
