Have you got a scrapyard round your way? Wiring looms robbed from autos are good for heavy-duty loads, such as motors, ESCs, etc.
And some bozo on this forum going by the moniker of PMK could help you out with smaller gauge wire for on-board lights, etc.
Name your colour.

I tend to use "mains leads" for heavy cabling ( batteries, motors, speed controlls.
If I want colour coded wiring, I buy it at the shows or Maplins, or the local DIY shop.

If you are buying small quantities then probably Maplin or you local electronics shop is the place to look.

I tend to use control system cable (16/0.2 or 32/0.2 depending on the load). Mains cable is not too bad, but you may be better stripping off the outer insulation. Best investment in my opinion is a big pack of tyraps and a big pack of cable tie bases. Tidy wiring is so worth the effort when it comes to fault finding and reliability.

Hi Garabaldy,

36V to 48V seems a little high to me - why so much? I would suggest that 12V to 24V is probably enough.

With these higher voltages, you will have to use mains rated fuses rather than automotive ones - certainly if you use 48V. Blade type fuses are only good to about 36V.

Connectors - if you use the red, blue or yellow crimps always use a proper ratchet crimp tool. The hand plier type do not give a reliable enough crimp. You can get them from car parts shops - better though to go to somewhere like Screwfix.

For small power use such as lights, I use alarm cable wire, lots of different colour cables.
