frodus replied to the thread Electric Race Kart build.
" Got the first mounting plate. The Manta 2 from Ebay DOES NOT fit the ME1507. The holes on the 1507 are different, also there's not enough clearance between the holes and the bend. I'll have to fabricate something for the ME1507. It does (barely) fit the ME1304. The holes could line up a little better, and there should be more clearance between motor and the bottom of the bracket at the bend, but it works.

Got the rear sprocket (28T) yesterday and got it installed in place of the old sprocket. Using one of the Amp front sprockets for the motor.

I got a Size 4 controller to try out from a Zero motorcycle. Will make a mount that can hold the size 4 or 6.

I got a 96V charger today and programmed with lithium profiles that should work well with a pack from 98V to 131V (over what the Sevcon can take) . I have a 72V charger if I need to go under 98V fully charged. "

" The dragbike is ready for its first test tomorrow. Not worried about any speed records,
just checking all of the systems, wires and temps before we fix all of the holes in the
body and get it wrapped.

Smokey burnout will be mandatory....

It has been 6 months now of playing with programming the sevcon and I will say that it is frustrating,(hair pulling?) even with frodus's great help and suggestions.
I am still trying to get it to be as stable the kelly and while i am still tuning the PID settings I am not yet having any better acceleration. At this point for me though the thought of going back to the kelly after all the re-wiring I did seems like too much work.

I am an engineer with a pretty strong electro/mechanical background so I am willing to put in the long hours to eventually make it work how I want. If you just want it to work right away however I found the kelly to be much easier.

So:
Pros for the Kelly: Turn Key install, Auto tune motor parameters, easy to use app to change settings, stable, less expensive.
Cons: Speed throttle vs torque throttle( didn't really bother me), equivalent start torque to a 350CC motorbike. that's about it.

As for my bike I am running a 96V chevy Volt pack with a ME0913 Motor.
Charles,
email me, I haven't heard from you in a while. Lets take a peak at the file you're using. You shouldn't need to change the PID settings.... but maybe the max torque is turned down low. "

" Update:
Motor mount (Manta 2) arriving tonight, the one from kartmasters should be here next week.

Ordered a 96V DeltaQ so I can play with higher voltage packs.

Ordered about 100 of the VL41M cells (41Ah saft cells). maybe 30 or so going in the Kart, the rest for spare and maybe another project/powerwall/testbench. "

No plans so far. There is a large inventory with my supplier of these Size 6 controllers and I'll be working to sell those before considering going to anything else. It requires a direct relationship with Sevcon and a large number of sales numbers per year. No one else that I've seen (EV Vendors) are selling those either. "

Awesome. Start a build thread if you haven't already and post some details of what you're looking to do. Lots of help here on the forum to get you sorted. "

" Whatever you decide, good luck! I understand the frustration sometimes with conversions. Some go smoothly, others are more difficult.

If you do end up parting out, I might know a couple people who are looking for that combo. I might even be interested in the controller for my ZX6 conversion!

let me know good luck "
