I use a similar home made setup for LSR events and my voltage stays consistant for the entire weekend without a charger. 
Since your runs are so short and doesn't give much time for a re-charge from the system. I would think eventualy both batteries would be down on voltage but probably after the 50 mark. |
That would be the route I would want then.
Last year I made 20 passes in one event. I went to finals in both classes, 1 practice, 3 qualifications each class and 13 elimination rounds. Toward the end the times slips were showing between 5-10 minutes per pass.
Starting before each pass,
Stopping at the truck for fuel or whatever and going back to the lanes.
Starting from the lanes to go to the front or get heat back in it. (earlier passes)
So I think I could have easily started it 50 times that day but I was pushing it to the line at the end.
I've won a pass from a strong competitor because he couldn't get it to start. After a few minutes he waved me on. I don't want to be on the other end of that.
