Low Profile Cable Glands/Cable Entry

[tmort]

I need to build a thin battery case to mount to a spot on a frame. There is plenty of room in some places, pretty tight others. The place where the wires come out the the pack are in a pretty tight area. The pretty common cable glands, especially for a larger cable like coming from the battery pack take up to much space.

I see there are some low profile cable glands and cable entry systems. I've only seen pictures of them other than seen a few that are sort of intact membrane and you poke a hole through them an run a small wire through them).

Has anyone had any experiences with any of the systems out there or spent some time looking into them?

Sorry, but trying to understand what "glands" means in this context. Are you talking about running cables internally through the frame, so the glands/entry points are covering the holes in the frame? So glands are similar to grommets? Or, are glands the connectors themselves? I tried looking up cable glands, but didn't see much ebike ralated.

Sorry, I just meant through the battery case I have to build. The pack itself has padding and some protective plastic and shrink wrap, but is not itself waterproof nor directly mountable. It is a triangle pack and will fit in a triangular space with different angles.

Do you mean something like this which is much lower profile but less waterproof than a more traditional clampy type?

I was actually considering a similar membrane setup to waterproof the cables on this vesc, while certainly not well IP rated it might be good enough, especially depending on what is inside. For instance I plan on conformal coating the ESC first.

Thanks for the clarification. My hard case triangle pack using those simple donut shaped grommets, with both conductors going through a single grommet. I'm pretty sure it's not waterproof. To get a better seal, I'd use two access holes, one for each conductor and grommet. I don't know what type you are referring to that are not low profile though.

The donut shaped ones are the first and second row:

Here are a few that I found online. I searched on low profile cable glands and later learned another term a

I found a 3D CAD drawing for a panel mount flange adapter for an XT-90 connector. I don't think I will have room for it, but that would be nice. I may have some room on the other side of the case though, so I haven't totally ruled that out.

I can always just use a grommet and fill the inside with a lot of silicone sealant, but I'd prefer to not go that route.

Those look like they have good water resistance. I'm cheap so the grommet and silicon would probably be my route, but can't argue with going with a higher quality solution.
