One cable gland to rule them all!
Water resistant charge port and power button. Waterproof PG21 cable gland. Waterproof IP67 junction box. Hell, even a waterproof remote.

This is also a big “gotcha” with making loopkeys. I remember the day I found about the holes… LoLz

Do you have a picture of that? Sounds like a great idea for my build. Thanks!
What about the sensor wires?
Yes
I don’t use them anymore, sensors just added failure points with little benefit. The sensors are the only electrical part of a BLDC skate motor that aren’t waterproof. Just get rid of them. Unless you’re using bindings they really aren’t necessary. They are a luxury. A luxury that can make the drivetrain fail more often.

Sensors with conformal coatings are waterproof.
Sensors are critical for low speed efficiency.

Thanks!
Actually, it seems like my range went up when I ditched the sensors. It may be because the hip flick to get the wheel turning saves some power each time, I don’t know.

Hmm, that could be it. But I would be surprised it contributed that much. What KV are your motors? And I am assuming you have 14 pole pairs.
170Kv yes 14P
I used extra Sugru I had to seal any holes I made. Works like a charm and very easy to cut and remove if needed.

I like Sugru, but it is too expensive, I rather use epoxy, and use a Dremel if I need to remove it…

Hey, just dug up this old thread and I was curious if anyone has thoughts on using Flex Paste for waterproofing. PHIL’S BACK AT IT AGAIN https://youtu.be/lrQKFmje6so

Does this glands are also waterproof when running multiple wires through them? Like if you get the board vertical and pour a cup of water, won’t the space between the toes let it through?

There’s a neoprene/rubber ring that inserts between the cables and the gland. When you screw it tight, it compresses the cables a bit and makes a very tight fit. I don’t think it would survive being underwater for a while but it definitely resists water. I made sure to pick the tightest gland I could cram all the wires through.

Nice, will take a look, never thought of using them because I assumed they only really worked for a single cable
Edit: it’s like this on the inside?

2 of these https://www.amazon.de/gp/product/B07JJZS28H/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 worked very well for me (IP68), just had to cut the yellow isolation ring after I pulled through the cables.

Nope, just hollow but that would have been cool. The wires and cable braid being compressed takes up all negative space. I considered putting some silicone on it but haven’t seen any signs of water or mud ingress to make me do it.
It was quite literally the smallest cable gland I could force all cables through.

I will look in these multi cable ones in the future, way easier than using connectors and the right ones will hold up even underwater for short periods
