Wire Sizing for Motorcycle Conversion

[Csecrist12]

I am having some trouble with wire sizing of each component in my system. Some of the following is what I have:
Curtis PMC 1231C Controller
K91-4003 Motor: K91-4003 Motor
LiFePo4 Battery pack of 32S 15P (102.4V Nominal and 116.8V Peak Charged)
ZEVA BMS setup with 3 12 slot modules
Thunderstruck DC to DC Converter in replace of the Aux battery for my 12V units. TSM 96V DC-DC TSM48DC-DC

I have the generic wiring diagram from Curtis that I would like to follow:

My question is, what wire sizing should I use where? The unit I have is limited to 500 amps Max as per page C-2 in appendix C (Very last page of the manual provided).
I am starting the build and ramping up my fabrication here in the next few months and would like to to have this topic covered.

Hi,
eventhough in german there is an online calculator about 1/3 down that page:
https://campofant.com/kabelquerschni...itt-berechnen/
Just hack in your numbers and hit calculate.
That will show your losses and from there its up to you to decide.
Most folks use 35mm2 i think and thats what i use.
Enough for 200 amps cont. you do not have to sice for max amps battery side.
Motor side you could bump up to 50mm2-
Just my 2 ct.

I appreciate the comment. I will check out the website to see if it's something I can use.

I've heard of people using the 35mm2 and the 50mm2 type wires for around the motor, but wanted to be a bit more specific not only with the motor wires, but everything else as well.
