Guest PogArt Artur Posted July 30, 2019 Share Posted July 30, 2019 (edited) Hi, just out of blue question 😋 Today is actually first time, I ever had rode in such heavy, proper rain 😎 This WET condition has made me a bit worry, because I didn't know what to expect. This is why I've started this topic,which is aimed to experienced EUC users - all weather condition. Dear friends - is it higher risk riding in the rain?, should I avoid?, or it's ok - please 🙂 ? * I mean the cut off the battery, if accidentally the water (rain) gets somewhere to the wires? Thank you in advance 😎 Edited July 30, 2019 by PogArt Artur Quote Link to comment Share on other sites More sharing options...
atdlzpae Posted July 30, 2019 Share Posted July 30, 2019 (edited) Wires aren't the problem. Water has a very high resistance, it won't do squat to wires & engine. Some ROV's don't even waterproof their engines if they are to be operated in fresh water. The only really problematic part is PCB. They're usually covered with varnish and mounted quite high on the wheel. A drop in the wrong place can disable/damage it. How often that happens is a different question though. :-) Edited July 30, 2019 by atdlzpae Quote Link to comment Share on other sites More sharing options...
LanghamP Posted July 30, 2019 Share Posted July 30, 2019 You can use wd40 on the pcb. WD40 functions as a water displacer, and is safe to be sprayed around electronics. Quote Link to comment Share on other sites More sharing options...
Michael Vu Posted July 30, 2019 Share Posted July 30, 2019 (edited) Light to medium rain is fine as the shells and placement of the PCB are adequately protected. https://www.instagram.com/p/BSYATIGF37f/?utm_source=ig_web_button_share_sheet Edited July 30, 2019 by Michael Vu Quote Link to comment Share on other sites More sharing options...

atdlzpae Posted July 31, 2019 Share Posted July 31, 2019 (edited) PCB = the motherboard of the vehicle/smartphone/laptop. There are two ways it can damage the board: 1. Corrosion. Louis Rossmann made a nice test of that: Corrosion is not that bad in fresh water, coca cola is WAY worse. 2. Electronic interference - for example a big enough drop may short the 84V to 3.3V rail and in turn fry electronics (that suddenly get 84V instead of 3.3V). It can also screw up with resistor values, temporarily disabling communication between chips. In practice you'd need a really good luck or a swim in the lake to get water into your electronics. KS16S it's pretty well protected from all sides, so that shouldn't be a problem. Also, the layer of varnish on KS is quite big - I had to scrape quite a lot to be able to solder the motherboard. Don't worry about the rain. Just don't go swimming in lakes. And no puddles higher than your feet. Although I've seen people on youtube go higher than their feet and it was working fine. :-D Edited July 31, 2019 by atdlzpae Quote Link to comment Share on other sites More sharing options...
Guest PogArt Artur Posted July 31, 2019 Share Posted July 31, 2019 Thanks a lot for PCB definition - lol 😋 I think I'll put a WD-40 layer over the PCB (now I know what it is 🤣). Thanks again ... Quote Link to comment Share on other sites More sharing options...
Jacky Heshi Posted July 31, 2019 Share Posted July 31, 2019 Maybe you should consider conformal coating instead of WD 40. It's a much cleaner process 1 Quote Link to comment Share on other sites More sharing options...

Could you provide the DIY process as well, how to apply it properly please? I'll search for applying tips as well 🙂 I guess it's external layer, not need to open the EUC to get to the PBC? Sounds easier to do - thanks 🙂 Quote Link to comment Share on other sites More sharing options...
ir_fuel Posted July 31, 2019 Share Posted July 31, 2019 No, you need to open the EUC and put a layer of it directly on the PCB. Quote Link to comment Share on other sites More sharing options...

I'll search for applying tips as well 🙂 It's not hard. You just take the applicator and smear it all over the pcb, on both sides. Use the UV light to check if you missed a spot. You can't put too much on it. Then leave it a night to dry. One thing to be careful with: if you disconnect any connectors do NOT apply the coating to those connectors. You'll isolate the pins and the connectors won't work anymore! Also be careful if the board contains push buttons (which I presume it doesn't). Same goes for those. Otherwise just apply generously. https://oscarliang.com/waterproofing-drone-electronics/ Quote Link to comment Share on other sites More sharing options...

Thank you for your patience ... This conformal coating is probably superior to the WD-40, so I will go for it. Thanks for great advices - to all of you guys.

Lol, that's the best advice ever 😎😎😎 You hit the point perfectly to be honest 🙂 It can be down to my preferences, you're right .., I can do something to look after the PBC, or leave it as it is, counting on the manufacturer's knowledge. I will do the conformal coating,though , I will sleep better 😁 Thanks again 😎 Edited August 1, 2019 by PogArt Artur Quote Link to comment Share on other sites More sharing options...
gena Posted August 1, 2019 Share Posted August 1, 2019 I ride all year with high mileage in the UK, lots of rain. I have the ks16s, 18xl and msx; so far no issue. Next time I have one of my wheel open, I might apply the products mentioned above though, just to be safer. Among the three wheels I've got, the one I fear most damage from water is the MSX because the water theoretically can sip through the trolley handles, the pcb is lower to the ground ( not 100% sure here ), and the shell is cracked. So I would say it might depend on your wheel as well. Quote Link to comment Share on other sites More sharing options...

That's very appreciate as you're in UK as well 😁 I feel much safer after reading your words, I should be fine too as well. I think my EUC is well build, so no internal leaking fear I guess 😁 I've started this topic to listen to the others, like you for example, as it was first time I rode in such rain, I had to go at lower speed too, because it was just safer as the water did cover the street holes perfectly. I'm commuting for two months now, so I'm mostly aware of the street's condition, but ... 🙂 Thank you. Quote Link to comment Share on other sites More sharing options...

winterwheel Posted August 1, 2019 Share Posted August 1, 2019 Riding in the rain for me has been fine, but you need to be careful to ensure the connection points are dry before plugging in the charger or you may wind up needing to replace the charger.
