Does this controller seem okay?

[l798757]

Hey,

I just got into this electric go-kart stuff and I found a very nice motor that I think will work perfectly - Mars ME0909 - 48V, 100A cont., 300A for 30 seconds. Full info here https://www.electricmotorsport.com/me0909-pmdc-motor-12-48v-4-hp-cont-12-8-hp-pk.html

Now, most of the controllers for this that I saw were from Allterax and were quite expensive. I came across this motor from Kelly Controllers

It looks fine to me. I even saw a video on YouTube using it (https://www.youtube.com/watch?v=QcgIBDyGtPc).
I just want to make sure that I'm not overlooking anything.

it'll be okay..

I think the one size smaller (300A max 120 cont) will do already

but for just 20 bucks more a 100A backup is surely something worth having,
especially since as you said Kelly recommends the 400A controller for the Mars 0909.
