Yep, 3.36v is about right. You only went .5 AH ? You must have a pretty efficient setup. I go around the block and I use at least 1.5 AH but I have a huge motor and I weigh about 267 lbs.

3.54v Oh that's okay. 3.54v isn't too far off. The cells settle down after charging to something like 3.55v . Yeah, most people run into trouble in the beginning by bulk charging a pack that isn't top balanced. I don't even check the voltages on mine anymore. Maybe once or twice a month, I'll check them. I know the charger is safe and that's all I care about.
