This is interesting.
Hey Jezza what is the weight of box unit ?
I’m building a unit for my mate using a ip68 rated box that will be bolted to a kite harness or in camel pack but the box is heavy 2kg alone. Will fit 12s 3p or 4p.
I’m using flipsky 150amp waterproof vesc
Great idea. Im currently looking at a new Pelican 1170 i bought and thinking maybe you have the right approach.
Weight seems OK, my diys Carbon sandwhich box that holds a small vesc, reciever and a 12S3P 21700 battery weights 880g including an aluminium heat sink laminated into the bottom.
Can I see a photo of your box?
Nice work. What box are you using?
Don’t be afraid to think outside the box–literally. I had a hard time finding a comfortable box that fit my battery. And they usually have a lot of sealing surface just waiting to leak. This system has been working great for me. Rocket Man.

Awesome! i need more pictures!!
Hi, what is the weight of the belt ? Thanks
Do you have more pics of your build somewhere, Foilfun? I don’t want to hijack Jezza’s thread
Where can I check them out? Would love to have them on my boogie
I guess I should consider posting a build thread. But I just built it without taking pictures of the process. I didn’t intend to derail this thread. I just went through different boxes before landing on a tube, so I thought I would toss it out there. I’ve never seen a tube foil assist anywhere.

@Jezza …Hey there, any further progress on fitting out the Duotone box with an ESC?? Ime very interested to see how that comes out.
Cheers

Things slowed down a bit! Picked up a heavy infection and have’nt been able to foil since June.
I’ve also had a load of other stuff on my plate as I was lazy with another design which I wanted to patent the concept (idea I had years ago) and then another company released a version roughly a week ago on social media so now I’m behind a bit on that too.
I’m in two minds about the esc. If I use an external IP68 one then its fast and easy to finish. But I have loads of VESC’s here so there’s a part of me that wants to use what I have and not spend more money. But that may mean needing to dril extra holes in the housing.
Hopefully over the next few weeks I’ll get something together though!
Jesus…sorry to hear that!..i hope you het back to 100% soon mate.
I was thinking of using one of these but like you say, dont want to start drilling holes in a perfectly good box.
Might try and fit a sequre 12200 into the bottom.

I bit the bullet and ordered the 6.8 flipsky off ali express. I’ll report back once it gets here
External esc is really easy and you have no issues caused by the heat of the esc within the box:
This way two 15Ah racepow batteries fit in easy which means > 600Wh in 2kg! 
I will test my setups the next 10 days in the ocean…

Heavy PVC plumbing pipe with screw on cap also works fine for backpack. Good quality caps have O ring seals and are designed for high pressure.
