Required amperage question?

(1/1)

Edemon:
Hello.. I’m trying to learn and understand basically by reading as much as I can..

I am looking at 5 to 10 kw motors and many look very impressive on paper with the torque and power ratings but are rated at 100 to 350 amps. I cant seem to find a single battery that has a constant discharge rate over 60 amps and most are 30 to 40 amps and rated surge amp at 60 ish.

Why are motors rated at such high amperage?

MickMick:
Start and acceleration torque requires high ampage. I could not find on that did what I wanted, so built my own battery.

Edemon:
How much amperage did you build for?

Knightgreider:
I built my own battery, you have to figure out the cells max amperage per cell and then see what the max draw and divide by the number of cells. I built mine out of 18650 cells.
