alright well that sounds right, I had been thinking that since the 12 cells will be double the capacity of the 4 cells, I want to stop before or when 1200 ma have been used, otherwise the 4 cells will turn effectively into a wire instead of a battery, which I would guess couldnt be good. Correct me if I'm wrong, its been a while since my electronics classes in college.

thanks for the advice, I'm going to make the 4cells pack removable from the series, but with gold connectors, I'll be trying this out in a few hours, and today I think I'm going to make a video, running the big lake today.
