I always use Google with site:electricunicycle.org to search this forum.

The video says the capacitors have "over 40% voltage margin" in the built-in subtitles, but the voice says "over 50% voltage margin". Is there any way to speculate from this whether it's 126V (+40% = 176.4V, +50% = 189V) or 134V (+40% = 188.16V, +50% = 201.60V)? Do any typical numbers match one or the other option? LOL this wheel robs me of my peace of mind. I don't even care, I just want to know.

Watched the video again. There seem to be 16 of what I think are battery cell slots, so it would be 134V. See the picture. The rectangular "tabs" next to the numbers. There are 15 spaces between the "tabs", so if the cells sit there, we have a 126V wheel. Does anybody know more about how the battery cells sit in an Inmotion pack and can take a guess what this x-ray view shows? 16 or 15 battery cell places? - To me it looks like it might really be 134V. 16 "tabs" for the outer cell column, and the battery pack is higher at the top (extra height above the tab number 16) because the inner cell column is shifted up by one cell radius.

If you do the V13 speed * 18/22 (or whatever), the Adventure would have to have a higher free spin speed. So the motor is different and seems to be geared more toward torque. Comparing speeds doesn't really work then. Never mind, I can't read. Getting 100kph free-spin from a torque motor is another sign that the voltage is high (at least 126V), though.

You're right! The hope is alive! Will it be 126V or 134V? How many mosfets does the V13 have? We might guess from that.

The motor is really interesting. Cannot wait to see a torque-off between this, the Patton, and the Extreme.

Was that the teaser or will there be more today?

1500Wh is a nice surprise, could have been 1110Wh! This is a great V11 competitor, and a great wheel to recommend to new riders who cannot/will not spend 3000+ moneys for a wheel or want a smaller tire! Has all the neat features. I also like the looks. I expected a S19-styled wheel, but this is nice also. Price? (And of course they had to rush the S16 info out before the Inmotion announcement, I don't think this is a coincidence.)

At this point, you could give some pictures, then we can strategize how to best get the wheel out of the water

Well... I don't think it is going to suddenly explode just because you checked the battery type. But maybe storing it in a safe place can't hurt. "In your room" might not be the best idea. Maybe just put it in the bathtub/shower, especially overnight and while charging (remove before showering though). Any place outside that could work? My approach to this is: a fire that only smokes but can't burn anything is better than a fire that can burn something. And if possible smoke does no damage, that's better than smoke damage. Choose your storing and charging place accordingly, if you can.

Compare the sizes (specifically the height) of the battery packs. Each pack will have 24 cells for 100V, 30 for 126V, and 32 for 134V. So higher voltage = taller pack. Use the tire (should be always pretty much the same size) as a point of comparison. Begode T4 (100V) - a pack is about as tall as the diameter of the metal rim, but definitely not as tall as the outer diameter of the tire. Begode Extreme 134.4V - a pack is pretty much as tall as the tire (a little less, but not much). And finally the V14/Adventure with unknown voltage - what do you think it looks closer to? My guess:

Just guessing. The light might sit on a metal cooling body behind it, and the fins are what you see of this body. But yeah, the lights on this seem to be great! In about 24h we'll know more hopefully.

Might be just the cooling fins for the light.

You only need a carabiner/hook or something like this, on a rope. Dive down, fix it to the wheel (maybe the handle bar), and then you can pull it out with the rope. Takes 10 seconds. No diving equipment needed. Maybe a long stick even saves you the diving part if you can hook the wheel from the surface.

Maybe the orange top shell is metal? It is quite simple shaped, so it doesn't have to be plastic. I would be surprised if IM design an "offroad" wheel like this and then have an obvious weak point on it. And even plastic can be very sturdy.

I don't think you need to be worried about a fire. You can always remove the batteries from the wheel on the spot right after you fished it out, and slice the foil so no water is inside. Then they should be safe. It's not like they go up without reason. My fire warning was meant so you don't try to re-use the batteries after fishing them out of the water, even if they "still look good" or something. I believe that can end very badly and is too risky. Here's a disassembly article for the 16X. You might need only a screwdriver to get to the battery packs. https://ecodrift.ru/2019/06/24/kingsong-ks-16x-disassembling/

It is smaller. The V14 has a 12 inch rim with a "16 inch" (= almost 18'' real diameter) tire size, like the Patton/Extreme/Commander Mini/Nikola/16X etc. The S19 has a 14 inch rim for a "18/19/20 inch" (something like 21''+ in real diameter) tire size, like the S22/S18/V11/EX30/Sherman S etc.

And so the PR battle between Inmotion and King Song starts

You only need a screwdriver to check the batteries. Open a side panel and read the sticker on the battery pack. Then you can sleep sound or be scared for a good reason, depending on the result

It sure has all the RGBs from the looks of it. Price under $2000! Nice! Now I wonder even more wtf the point of the S19 is supposed to be. Paying 700-900 more for a bigger tire size? Or maybe this S16 will be 84V 1500Wh? Or 84V 1110Wh like the S18?

It has a proper, truly usable, bright backlight!

Oh wow this makes this doubly sad

Some discussion about the term "hydraulic" has ben moved here: Thanks @dycusfor summing it up so succinctly.

I almost just stickied your post when I saw it, but wanted something as concise as possible that has all the information (and the word "fire" in the title") so I just finished what I had already written. Hope you don't mind Thanks for the suggestions! I kept the first quotes as they are, in order to stay as simple as possible and not worry people unnecessarily. I changed the "throw out" part though because it was indeed badly worded.

The fire danger was a bit exaggerated by me. The batteries are likely already discharged from being in the water if water got into the battery, though I'm no expert on this, so I don't know. You can probably remove the wheel safely from the water, I don't think you need a fireman for that, they don't explode randomly, just when they heat up too much from being shorted. I would remove the batteries for recycling (maybe remove the foil so no water can stay in there) and then see what you can do with the rest of the wheel (like does the motor still rotate smoothly etc.), but probably you just throw that away too. Sucks But definitely do not try to charge the batteries ever again, too much that can be wrong with them that you couldn't see, that would really be dangerous. And I wouldn't store them anywhere where a fire could be a problem.
