Ah, now things are clearer. Why not setup your electrical system so that you carry one gel cell battery (no
Odessey at this point) in a quick-change manner? Leave the other gel cells (how many did you get from your
friend?) on the ground on a fast charger. On each landing, swap the gel cell with the most charged one on
the ground. When you've finally got the blade tracking problem solved, go back and install the Odessy 680
as your permanent lightweight battery.

I don't need to switch out a gel cell each time. I can do exactly
what you indicate here by simply hooking up to the APU each time and
leaving it on the fast charger. Then I don't have to carry the weight
along with my big gut each time.
