Re: Drive Train Calcs - Not trusting my results

I never even thought of the battery voltage drop. I'll have to find that math. I'll add voltage to the spreadsheet. I might have to come back and ask for help on how to estimate that voltage drop, though. It seems like that should help me get a more realistic estimate of how fast the gearing can be while still being traction limited.

Related to post 2, I did notice how flat that curve is for 10-15 ft sprint times. I don't really understand why anybody would want to be on the fast side of that sweet spot. What is a good reason for gearing it to 17 ft/s when 12 ft/s gets you there just as quickly?
