Thnx, 3series.
Dinball offered the bearings

On my Overland I noticed more a longer lifetime of the cells than anything else.
Oh, and of course, the wheels spinning for 2 minutes after rolling over, LOL!
I wonder if I can connect one wire to each o + and - holes that exist in the esc and that lead to the ends of the battery package...
I would surely charge the cells, but is there any risk of burnig something on the ESC?
