A 450 amp alltrax AXE 7245 controller can handle 200 amps continuously and would cost about the same as the parts to build an Open Revolt controller... or for just over $300 you can get an Alltrax SPM 300amp controller that can handle 210amps for an hour+

I have a $20 battery cut off that works with lithium batteries that has two outputs a timed and a non timed trigger, so you could have the first trigger give you half speed "limp home mode" and the 2nd trigger cuts all power to save the battery pack from over discharge.

I like speed controllers over just an on off switch, the smoother start is easier on the motor and batteries and you can have the motor more directly power the wheels instead of needing a transmission.
