Hey Folks. Finished up my go kart...ended up with some pretty big issues with the motor/controller. I had it working, then it wouldn't (on repeat...many...many times) When it was moving, it was working great! So, I decided to part it out and start from scratch on a simpler project. Going to be doing a Big boy scooter.
So I have questions... I keep getting mixed answers about compatibility between motors and controllers and batteries. So here is what I'm thinking...Let me know if you see anything that won't work, or could work better.
Battery (owned already):
-72V LiFePo4
-40Ah
-80A continuous
-160A 5S peak
-onboard BMS
Controller (NOT owned): (is this too big? too small? I was leaning towards this or a 70A controller, but its hard to find 72V ones to take advantage of my battery)
-72V compatible
-80A
-max 200A
-rated for 3000-5000 watt
-Temp regulated
Motor (NOT owned):
-hub motor
-17" total tire height (big I know, meant for bike)
- 48-96V rated
-3000watt (I know this varies, but this is rated)
Since I've got a 72V battery with 80A continuous...should I be looking for a motor that is rated for at least (72 x 80) 5760Watt? What would happen if I ran a 3000 watt motor..would it burn up eventually or just get warm? I'm mostly stuck on the motor. Its actually pretty darn hard to find a motor over 3000watt that runs on an 80A controller. Most of them want 100+ . Also, what happens if I run a 10000watt motor? what would happen...just wouldn't reach full potential or would it wimp out or something?
Suggestions?...
