- The most important thing is to have the will, patience, and time to carefully follow the directions in the video.
It will help to familiarize yourself with the intended Two-X wire routing. Here are some pictures of a well-done installation, with the wheel removed for a good view of all the wiring:
Think of it like building a new Lego kit. Except with a so-much-more-awesome result. Be mentally interested in taking on a challenge before you start, and enjoy the process. Once it's finished, and you go to step on it for the first time, pay attention to any differences in how it feels. Any sense of accomplishment you feel at this moment is fairly deserved :)
After Your Install
Directly after your install you are excited to ride your new board and try it out and do range tests or whatever. So you're not gonna like what I'm gonna say next.
I mean, go ahead and try riding it around a little, that's harmless. Just for 15 minutes or so, but don't go more than a couple miles. Because before you do any more than that, you really should do a full balance charge, to let all the cells completely balance to each other.
To do that, plug in the charger, and leave it plugged in (even though the light will turn green) for 24 to 48 hrs (the longer the better). You can watch the slow boring balancing progress using pOnewheel android app if you want.
There. Now you can go nuts.
Notes on Weatherproofing
Here's where I use some scare tactics to help you ensure your board doesn't get ended by water leaks. When you are in there installing Two-X is the perfect time to re-seal your battery box. Regardless you will need to seal the passage through the gland where the Two-X wires pass through, but you should check all the stock seals as well because they tend to age and fail.
Here's what can happen when water gets in to the battery box. Don't let this be your BMS:
Look how an innocent quick dip through a stream can violently demolish a onewheel in minutes.
It turns out that the provisions for the onewheel battery-box water seal are not commensurate to the consequences of its failure.
(Yes, I am totally kidding about "Inspect lid before every ride". As if ;)
I advise everyone, before you ride thru a single puddle, to pull out your battery box and overhaul its seals carefully, to your own standards of weatherproofing. Whatever those standards are, they'll be better than what you're rocking now.
Here is some good goop to use for this: 3M 08008 ( http://a.co/d/e2DbfL8 ). If you prefer using bad goop, you can use RTV or Silicone available everywhere.
Here are some steps to seal the battery box:
- Ensure foam gasket on box top is squishy enough and seating correctly all the way around. Check its coloration for evidence of liquids or particulates.
- Keep Two-X wires from being stuck between lid & box sides, jamming seal.
- Check the sheet metal lid is flat, not bent too much between each screw and that the screws are tight, uniformly, to seal well.
- Add a bead of sealant around the LED window gasket
- Fill the gland passage with sealant to fill gaps between two-x wires.
- Check the gore-tex pressure vent is sealed all around and not tearing off.
As for water seals of the Two-X satellite packs ...
Although the satellite packs contain no active circuitry and no voltages higher than 13V, they are very hard to open, so if water gets in there it'll end up corroding stuff. Unless they get damaged, water can only get into them through their tops or around the wire entry point. Vibration can eventually cause the rubber sealant to fail after heavy use, so periodically you should check the seals and reseal them. Here's how:
First, identify suspect areas to add sealant:
- Unscrew the two housings and flip em over in place. check the seal around the edge of the box lid, look for open cracks or any non-continuous rubber features which could be a way for liquid to get in.
- The entire ring where the wire insulation interfaces with the existing elastomer sealant should be re-filled.
- Same goes for the interface between existing elastomer sealant and the walls of the lid and box.
Now seal em up! :
- Squish the 3M sealant goop all down into any cracks with your fingertips. Eeeeew squishy!!
Yer all done.
