hey everyone I'm trying to make a electric city car.
the idea is an enclosed reverse trike with tandem sets (1&1 or 1&cargo), I'm taking inspiration from a few experimental designs like the "one sharp rickshaw" (https://www.yankodesign.com/2017/01/12/one-sharp-rickshaw/) and even the dymaxion. the two front wheels will be independently controllable with a steerable or caster back wheel. making it a mixed steering setup and will give the car a zero point turning radius at slower speeds
so I've bought two 4kw proud eagle motors used on e max scooters. max power of 6kw, max current of 100A, more then 80n.m torque, can take a 11 degree hill with a 600kg vehicle and at 72 votes can do 50mph/80mph (all from the makers website)
so i need help choosing the controller and the kinds of battery.
first question obviously i at least need a 72 vote 4000w controller but they're harder to come by and more expensive. would I correct in believing I could use a 5000w controller instead with no adverse effects?
second question is about the batteries.
I'm planning on starting with a 72 vote 60 amp set up, thats 4,320w so i should be able to drive the motor for at least an hour, then hopefully double that later. I've settled mostly on choosing between the 30amp or 60amp the LiitoKala lifepo4 batteries. the only reason i have for the 30amp is because i believe the max discharge amps should scale like normal amps but im not sure that matters. both the 60 and 30 amp batteries say they have a CD of 100 amps or more (60 says 180a) and a MD 300a for both. that beyond the max amps for both the motor or any controller i was looking at.
then am i wrong in thinking that I should just go with the 60a batteries then?
i would love any input you can give me
