The video of you paragliding your opensource DIY ewinch (your youtube channel you posted at the start of this thread) is very Wright Brothers inspiring. Love it. Good stuff!

I am currently using a daly bms with charging only.
Next time I would put it in the very front to be able to change it on demand.
Do you have any recommendations for a reliable bms (12s lion)?
45mm hight, 100mm width
1,5mm alu
It was my first time on a winch ever (after a lot of testing of course).
I think the feeling was close to the Wright Brothers feeling :-).
I still have not yet tested any other winch but have already 100 of starts on mine and could not think of anything better.
STL for the front of the travel battery (bopla box)
STL for a improved gong motor mount (more stable + cable)

And you have there additional support around the screws? Otherwise 1.5mm maybe too thin…
Many recommend LLT bms for 12s I have not used bms, another common option is having only balancing cables and jst-xh sticking out, for RC charger

Thank you for validating the design 
. I’ve started the same build now. Gave up the probematic gen1 box and took all the parts out.
I have a 5mm carbon plate 3k quality lying around. Considering as bottom plate instead of the alu, having M3 bolts sticking up to mount a 3d printed lid.
I don’t like or trust BMS at all. Therefore, the battery for my fd v2 version will look something like this. Which version of vx3 did you use, regular or vx3 pro?

I use the regular vx3. Connection quality is amazing! What is your 12 pin Connector?
Consider thermal issues in your material selections. Pot all electronics all around.

This is a balancing connector for an 11s battery. I would have preferred it to be smaller, but unfortunately this is the only one I have found in a waterproof version
What power connector is that?

any way to get that power connector to the US, I google it and it only comes up on Russian aliexpress
how thick is your aluminum?
2mm (for the second prototype with replaceable battery, etc.)
Love your simple concept. Avoiding mechanical stress/load from foil! Where did you get that aluminium box?
