I started a thread over on diyelectriccar car but figured I would start one here too. I have yet to find a post on a complete build but plan to create one here and will try and keep updates. I hope to have it done within 2 months. I will start off by coping most of my posts from there and try to share any info from member of the other site. This site probably needs it more because of the members it is geared too.
This is my first build and I am new to the ev world. Gonna be on an old kart racing frame with slicks. I have been reading for a month trying to find info on all the ev sites I could find. Finding used parts is very hard if not impossible without months of looking/waiting so I am going used cause I want more power than a bike but less than your typical ev.
Specs looking for are 8+ hp cont and 15+hp max. This is just a fun kart but want to stay around $1000 not including batteries. I am gonna use some free 7amp/hr batteries at 72v for now until I kill then switch to 4 12 amp/hr batteries @48v until they die also. So I know they will hold the performance back until I swap them out
Any and all input is welcome.
Cloud electric seems to be the cheapest and has most/if not all the parts.
Motors are narrowed down to these in order of my perceived preference of the most power:
ME0709 $485 BRUSHED 24-72V VDC, 125 amps Continuous, 300 amps Peak 1 Minute http://www.cloudelectric.com/product-p/mo-me0709.htm
Recommended by someone on endless sphere but I dont think it meets my specs plus the controller is more exspensive.
ME4201 $394 BRUSHLESS 24-72V VDC, 90 amps Continous @ 48v http://www.cloudelectric.com/product-p/mo-me4201.htm
ME0909 $374 BRUSHED 12-48V VDC, 100 amps Continuous, 300 amps Peak 1/2 Minute http://www.cloudelectric.com/product-p/mo-me0909.htm
ME0907 $394 BRUSHLESS CONTROLLER EXSPENSIVE http://www.cloudelectric.com/product-p/mo-me0907.htm
I have found a slightly used ME1003 for $500. It is basically the 0709 but made to sustain a higher continuous load. SO for about the same price I get a better motor and if I sell it in the future I wont take as big of a money hit on any loss.
Cloud has a package deal with controller but u only get about $12 off and they max at 300amps so package deal doesnt look so good if you actually want a different controller. Shouldnt I go bigger on the controller so it isnt maxed with the ME0709? Like say a 400+ amp controller. Plus if I ever go with a bigger compatible motor in the future I would like to not have to buy a bigger controller.
Looking at Kelly or Alltrax.
Is regen or reversing worth it? I dont understand the specifics of making them work yet. Regen benefits seems a moot point though.
Some type of emergency disconnect like an Anderson plug style?
I found a nice diagram from alltrax on another build thread this helped immensely with the parts needed as very few people mention the small parts.

I have the parts narrowed down to these if I am correct. A couple parts are different variations as I dont know what to get. I am thinking just have the emergency disconnect and anderson style plug. Then I could do away with the key. I believe I would then need a throttle with no switch. At least according to the diagram.
