The advantage of Floatboxx aluminium box compared to other type of boxes:

  • Strong ! Does not break under heavy use
    • Aluminium welded construction
    • Stainless steel inserts for the lid and rail mounting
  • Practical
    • The VESC can be mounted on the bottom and fixed on the M3 threaded studs.
    • More space for Buzzer, BMS, rESCue, extra Li-Ion cells...
    • Easy access for DIY: Just remove the footpad to access the lid. No need to remove rails, bumper, connector cover.
    • Easy to waterproof: welding imperfections can be closed with silicone/MS Polymer/...
    • The handle remains fully available
    • Mounting holes for 3D printed LED strip holder
  • Improved heat dissipation for the controller:
    • The box is completely made of aluminium allowing optimal heat transfer.
      • The area for the controller mounting is NOT powderpainted for optimal heat transfer
    • There's an air channel between the bottom of the controller box and the bumper
  • Durable:
    • the 2mm foamrubber sealing is compressed about 50% so the elastic properties are maintained after many cycles of opening.


  • rails: stock, Thunderrails, Varials, WTF*, Badgerwheel rails*    (*requires some grinding of protrusions in the rail)
  • bumpers: stock, BANGS, Badger bumpers* (*requires removal of the ridge near the wheel)
  • footpad: stock XR, DIY footpads 


  • aluminum box with aluminum lid (both powderpainted white)
  • aluminium Connector Cover (before sept 12th, this was optional. Now it is included standard)
  • foamrubber sealing sticker
  • 2 vent stickers
  • all nut 'n bolts in stainless steel. 
    • M4 lock nuts and washers for the Molex 6-pin connector
    • M5 countersunk screws for the mounting of the box to the rails, and the connector cover to the box
    • M3 countersunk screws for the lid
    • M3 lock nuts and nylon washers for the Little Focer
    • 2 square spacers to fill up the gaps in front when using Bang Bumpers




The connectors should be purchased separately:

  • on/off switch: ø19 mm hole for the switch, wall thickness 9 mm
    • Pre-wired available from MakersPEV/Customwheel.
  • charge plug: ø20,5 mm hole for the Neutrik NC3 MPR-HD XLR
    • Pre-wired available from MakersPEV/Customwheel)
  • hall/footpad: 2x D-shaped holes for Switchcraft connectors
    • Prewired from MakersPEV/Customwheel have typical too short wires (~100mm). Ask them for 200 mm wires or buy an extension set from Floatboxx.
  • battery harnass: ø20,5 mm hole for M20x1,5 cable gland with lock nut.
    • Make sure you get the variant with the 22mm dome nut (not 24 mm)!
  • motor: compatible with the Hypercore 6-pin Molex. Note that we designed for the Molex 6-pin with the gasket outside the box:
    • Build it yourself with these components
      • Molex CONN PLUG HSG 6POS 5.84MM 194290044, panel mount w/o boss (digikey link)
      • Molex CONN PIN 14-16AWG CRIMP TIN 0194170027, male pin, 6x (digikey link)
    • Buy a pre-wired Floatboxx set from Customwheel.shop for 24,79 € including the motor connector, M20 Cable gland and their compatible internal charger connector. Or contact us for a USA supplier.


  • We use metric screws and tools: M5 to mount the box, M3 to mount the lid 
  • Floatboxx is not guaranteed to be waterproof on it's own. Do a visual inspection first for small gaps. For 100% certainty: use the Badgerwheel kit . Total waterproofness depends on the complete assembly by the user.
  • Use a 1 mm thermal pad between the box and the Mosfets. The location of the VESC controller has no powdercoating for optimal heat transfer.
    • we advise 1 mm because we supply a 0,5 mm nylon washer to go below the Mosfets as electrical isolator
