Floatboxx CXC V2 BLEM
The Floatboxx CXC is a metal controller box to house a VESC controller between XR style rails.
It is specifically designed to go with the Superflux motor:
- improved thermals (at least 2x the heatcapacity of the MLC box)
- Fungineers MKII motor connector or M20 cable gland for the motor cable
- M10 cable gland for the footpad cable (optional stock connector)
The connector cover is integrated.
Weight: 950 gr = 2.08 lbs (box, screws, lid, seal)
This BLEM variant is not perfect. Usually a gap in the welding or in the paint. It is perfectly usable, but possible needs some more care waterproofing.

The connectors should be purchased separately, these are the size of the holes:
- on/off switch: ø19 mm hole (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)
- footpad: ø10 hole for M10 cable gland (optional stock connector cable to 3-pin JST for Little Focer
- battery cable: ø20 mm hole for M20x1,5 cable gland with lock nut.
- motor: ø20 mm hole for M20x1,5 cable gland with lock nut or the Fungineers MKII Superflux connector
Notes:
- 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
- We try to spray the powder-paint thick to seal all the corner-gaps between the plates. However, this means the powderpaint can accumulate at the far edges of the boxx (the edges that go inside your rails). The bubbles of paint at these edges can crack during curing. As this does not affect the function, we ship these as acceptable Floatboxx's.

The Ubox kit includes the controller mounting plate with studs to mount the 2 included aluminium brackets:
- A clamp down bracket for the Ubox 100V
- A mounting plate for the Ubox 80V
Thermal paste (not included) should be used between the controller and the plates.
The mounting of the controllers is waterproof, there is no other sealing required !
