General new build questions

Hi everyone! Looking forward to my first ever build. Been riding since 2016 when I got my first electric skateboard, an Evolve Bamboo GTX. I then switched it up to a Backfire G3 Plus and then a Backfire Zealot. I just purchased a Kaly XL40 this year, but still can’t get enough. I want to build a street board and got a few questions regarding the build. Current parts list:

  • Landyachtz Evo Spectrum 40" deck
  • @Eboosted SS enclosure
  • @3DServisas Fatboy mini urethane V5 straight gear drives 240mm with both Kegel and Abec adapters
  • @Boardnamics adjustable base plates
  • 2x Flispky 6374 motor 3500w
  • Lacroix Stormcore 60D VESC
  • Flispky VX2 remote
  • Various fasteners from Aliexpress
  • @torqueboards 110mm arctic blue wheels
  • Cloudwheels 120mm orange wheels
  • 12s4p Molicel P42A battery from @BOUNDMOTOR with charge port and charger

Problem is, the Boundmotor battery does not fit the enclosure, so I plan on keeping it for another build and wanted to build my own from scratch using the same kind of cells (Molicel 21700 P42As) in a 12s4p configuration. I plan on following the schematic from the @Eboosted LY Evo SS enclosure listing and using the same 12S BMS from his site.

First question is, would all the electronic components I have work with each other, or is something off?

Second question is regarding the battery build. I’ll be using the duck battery systems pure nickel 21700 4P P-group tabs. What size wire do i use to connect between the positive and negative ends and how many for each? (I see @Eboosted using 3 per group). And what size wire do I need for the positive and negative leads that will plug into the ESC? How would I wire the BMS for charge only?

Third question is regarding the switch. I know the Stormcore 60D has a switch already, but do I need to install an anti-spark switch and wire it into the BMS? I keep seeing that word pop up while researching battery builds.

I’ll ask more questions as I get further into the build as I have not started yet. Still waiting for cells and need to purchase a spot welder capable of the 0.2mm thick nickel tabs (either Kweld or Maletronics). Thank you so much!

Using xt90s is the safest way to prevent damage. Wire your BMS as charge only. Everything else you have looks good.
