In this case I’m not sure I would recommend what I did but I think its workable. I used both epoxy and then silicone.
Normally I would prefer a spray on silicone conformal coating but that would not work for the davega without some very careful masking of the screen and plugs. Too hard basket for me.
There are a couple of things that make conformal coating the davega trickier than your average PCB. The LCD and the gap between the two boards.
I used epoxy to seal around the edges of the LCD screen and the easy to get to contacts on the bottom. A brush on coating would be better for this as the epoxy tends to go on too thickly. I had to go back and scrape off some around the screw mounts so the davega would fit in the housing.
I read on the old forum that gluing battery cells with silicon could damage their shell, but in practice silicon seems so neutral and harmless I think people might have just mixed it up with something else.
Yeah, it’s still 4 wires. It has other advantages though. DAVEGA could remain on even when VESC is off and read/show data from a smart BMS (DieBieMS) while charging.
Here is how I mounted it. Might be useful for people with a trampa board aswell. Although on a holypro deck would be more difficult to install I believe. So I basicly drilled a hole and filed it to fit the connector. After that the install was easy… it looks so good . Sorry to possibly making you guys impatient now lol
Be careful not to get water in through the hole where you routed the cable.
BTW, it’s easy to unpin the wires from the JST housing. There’s a ton of videos on how to do it. If you unpin them before routing the cable, a smaller hole in the deck is sufficient. Just drill a round hole. No need for filing. It’s easier to find a grommet for it as well. Sorry, I should have mentioned this earlier.
Yeah i’m gonna design some tpu gaskets to make it at least splash proof. And np I know about unpinning but I have a bad experience with the locking fins breaking off.
