Thank you. I do understand now that you can't increase mph and distance just by doubling the batteries. It's one or the other. As I said, I would rather increase the distance. If I kept the mph to 30 and under, I could register it as a moped...
I think I would have to redesign the frame to accommodate 16 batteries. I need to do that anyway for trips to the grocery store. Basic question (that I'm sure has been asked 1000 times), Would it be easier for me to take like an old VW and convert it rather than starting from scratch? I'm thinking it might, being that this is my first build.
Another question: can a LiFePo4 battery work along side of regular batteries or do they all have to be LiFepo4?
I also want to thank everyone for helping me understand things. You have to start somewhere and the only thing I know to do is ask dumb/basic questions

I could see 8 being around 35-40 mph, or 20-24 miles at 25 mph, but you can't double both factors by only doubling the batteries.
Just hypothetical here, and not considering ANY losses, to double your speed and double your distance, one would need 16 batteries. Then we get into all of the great points everyone else is making, and other factors like temperature, and road conditions that can also affect your performance.
Not trying to burst your bubble, but just noting without any loss at all and just using math, you would need 16 to do that. Real life, with other factors, I would hazard a guess of at least 20 batteries at that rate, but under 32.
