Light Assist Season 2

What epoxy did you use?

Looks like BMS is located here and fully potted.

@Jezza MG Chemicals 832TC Themal epoxy.

Here is the current state of the system, with both batteries and the balance board.
The latch got very rusty, not good stainless steel, and I dont even ride in salt water most of the time.

I did not solve the pod situation yet to design and produce a really Quick release pod.


Files are now mostly sorted and available for anyone to replicate, just PM me if you want the link.

Updated the onshape doc with build infos and pictures. What is missing is the materials and print parameters (infill/walls)

Thanks for sharing.

832TC thermal conductivity seems pretty low to me -

Instead of the metal hatches, should be possible to connect battery and housing using the same principle and universal strap as the nano pod uses, one on each side, especially if combined with mechanical design to lock it in place first, offloading the strap from doing the static fixation?

-15 sessions - no rust.

Looks really nice. For fun I added a 3D printed latch to your model where the latch can easily be replaced if it breaks. I’ll let you know how it works.

Working on a way to install my assist under the pump board to do a tow setup.


The pod was printed then fiberglassed as I did not have confidence it would hold.
It is very messy as I did not have a proper set-up for vacuum.



I will most likely need to install a bar on the back to give it enough stabilty.

Plan to test it tomorrow :rocket:



First test was not a success, but everything works, including the signal wich is very good with the extension antenna, without direct connexion to the main antenna.

At around 30% throttle, the “boat” start to rotate and the prop comes out of the water. Probably needs a bigger board/boogie.

Maybe make some outriggers.

Hi Adam! far too much weight at rear of board ??? You always try some crazy experience :upside_down_face: ! thanks for sharing !

Needs to be wide and flat at the back…stops the twist and roll you get from a thin transom/backend
Also…movebrhe engine.much farther forward. Does thia board have tracks??..if it does…use it with an ali.mast and engine pod…gives you a ton of trimming options. To far back and the nose will rise…more.towatds the middle and the board will flatten out…trimming.is also.a.function of weight distribution (battery box) and motor position.

Had two sessions, first with 30q pack and 4.2", in the choppy water it was not effective and I fell a lot without catching much waves.
Second session with 35E and 7’2, much batter, but still a lot of falls.

Regarding potting the battery and esc into 3d printed shells using casting epoxy, is it recommended to single pour with a casting epoxy made for deep pours (lower exothermal reaction) or use any casting epoxy and incrementally pour the layers to keep heat manageable?

I gave up on epoxy after I noticed a crack. Had to take apart the battery with a hammer )
By the way, I bought a new VESC controller. It fits perfectly into the side panel. I hope to try it soon.

what product did you eventually choose for potting?

I use 2 Part Electrical Silicone Potting Compound

@Bzhwindtalker Regarding motor pod material, instead of tpu, this one is better:
