I have been thinking about battery configuration some more.
I have 12 batteries that are 12 volt each. Each weighs about 75 lbs.
I have a 400 amp, 48-72 volt PWM DC motor controller.
Therefore, I need to use either 6 batteries in series or six PAIRS of batteries in series for my battery pack.
I really can't do the math to figure what the car's range would be, because I don't know how many watt-hours per mile it uses yet.
The advantages to using 6 batts in series is the I shouldn't have to get too wild beefing up brakes and suspension, and the batteries should fit fine under the hood and in the cargo compartment. It also leaves me with a "spare" six batteries I could keep and use later.
Using all twelve batteries would give me much better range, but I would also need to beef-up suspension and brakes, and find a place to put them all. I think that would mean removing the back-seat, converting it to a 2-person car. I would then build a low box in the whole back of the car - something similar to a CRX or Insight, with room on top to use use for storage, carrying groceries, etc.
hey Darin, how many watt-hours per mile is the Forkenswift using right now?
Anyone's thoughts on battery configuration?
