36 volt vs 48 volt driving

Post by reed » Fri Dec 14, 2018 8:35 am

Is 36V tennable for an electric cart? Or is 48 volt a must? Looking at 2000-2500 lbs.

Just remember, whatever voltage you end up with, ya gotta charge it. That's why I go gas engine.

As long as the horse power output is the same, and the controls and motors are 36 volt why not?

All things being equal, meaning availability of motors, controllers, batteries, etc. going 48V saves a bunch on copper costs to run all that torque.

You should look at locked-rotor current on 36 vs 48 V motors, cuz that is going to drive your power cable thickness from battery —> controller —> motor.

But, with a super vague ask, you get super random meh answers.
