@Slartibartfast See what I mean by wishful thinking?

I don't know. It gets brought up here again and again (not by me). May be wishful thinking, and there was some spec sheet image posted that mentioned a "Monster2" with 70pkh etc, but all that could realistically just apply to the current upgraded Monster. This might be an msuper V3 - Tesla-ized msuper V3 - msuper X situation, where they upgraded the old wheel with the latest board and motor (did that for the msuper V3, just like they did for the 84V Monster now) and one month later the new one (MSX) was announced. Or this genuinely is the upgrade, all Monsters have the MSX board and motor now, and nothing new is planned. I really don't know. Until someone can confirm there's a new shiny prototype or something, I wouldn't know of any substantiated info.

Charging speed is proportional to the A of the charger until the last 10-20% (number actually depends on the amperage of the charger, but for simplicity just assume it's the same between chargers). The last 10-20% is always at the same speed. So charging from anything to 80-90% (or whatever) is 5/1.5=3.33 times faster than with the standard charger, and the last 10-20% take roughly the same time as with the standard charger. In other words, filling up is over three times faster, but the final topping up takes more or less the same time. What part takes how long, you have to try. But this can help you estimate. - So if you ever go for a looooong ride and need to charge in between, don't waste your time with charging to 100%, just continue the ride at 80%. Rinse and repeat. This gives you the most efficient use of charging time. Works for every charger. (If you have a charge doctor or the charger displays the current, you can see when the current starts to drop, and check the according battery percentage where the charging starts to lose time efficiency.) - @Chriull may or may not be posting a lot of graphs soon

New motor (2000W) from the MSX. New amazing fat-mosfet best-of-them-all board from the MSX (only the 100V Monster had it previously, the 84V had the 2 generations old and weaker ACM/msuper V3 style board). Makes the 84V Monster go from "eh" to "f**k yeah". A Monster redesign may or may not be coming in addition.

That's definitely true. Knockdown? Your video is great info, it's only about the interpretation. I just want to know if KS are indeed more efficient now, or if it's something else. (Also, defend GW against possibly false allegations, there are enough true allegations already) Winter + manufacturers is driving me crazy. Didn't intend to do that to you

Haha. You're not totally wrong here It just seems we have 90% accurate information on our wheels, and it would just be nice to have 99% accurate information. It's frustrating to wonder and speculate instead of just know. Whatever the result is.

That wasn't the point. Just that at 97%, your msuper V3 simply wasn't nearly full while (probably) the 18XL was at 100%. (Also, to defend GW's honor a bit) You could just keep the charger in overnight in your ms3 (it has no diode, right?) and then it would be full. And then repeat what you did, no need to ride it down to tiltback, just a reasonably low number where both the GW and KS formula will agree. But you have so much experience already, if you say you get more range out of your 18XL than your msupers, it's likely true. Good enough for me. Just enjoy riding and keep doing range tests

1% Gotway and 1% KingSong are not the same. It's more like 1% GW = 0.9% KS. A Gotway % is less energy than a KS %. Gotway says the wheel is at 100% at 82.25V, so if you keep charging to 84V after that you gain an extra ~10% capacity, but it won't count higher than 100%. I don't know what the KS formula is, but assumedly, for them 84V is 100% (unless they do the same s**t GW does, then my argument is completely moot). So 97% on a Gotway would be equivalent to 88% (estimate) on a KS, despite being the exact same charge state (=voltage) of the battery pack. ... And now you run the battery down. Empty is empty, so towards the lower end, GW and KS will agree on the percentage for a given battery charge state. Than means it looks like you use more % on a Gotway compared to a KS, when in reality a GW% is just less than a KS%. A full Gotway would be like 110%, but you only ever started at 100% or even less (97%). That's where the missing percentages go if the GW is not actually fully charged at the beginning, but the KS is, while both wheels will display around 100% at the start. On the ride in the video, you take your GW from 97%(GW formula)=88%(KS formula) to 30% (example number, both formulas will agree) and your KS from 100%(KS formula) to 40% (example number, both formulas will agree). 60% (KS% to be exact) each time. So much for the theory. If KS also uses such a strange formula missing out on capacity, then the 18XL is just more efficient and that's it. But if GW just hides away 10% capacity while KS does not, no surprise you get less range on the same battery. - @palachzzz Do you know at what voltage the KingSong app formula considers the battery at 100%?

Post the tires you use, a short description, maybe some pictures, and a link where to buy - 16 inch Kenda offroad/winter tire. Fits any 16 inch wheel - Tesla, ACM, KS16S, V8, etc. Available in black, red (looks great!), and blue (also available in 14'' and 18'', but I found it only in black). The knobs really dig in in snow, mud, on wet grass, etc. and provide good traction. This prevents the tire slipping (spinning in place) when climbing out of small ruts, which can happen with the standard tires. The tire doesn't seem to hold for too long because the rubber is thin outside of the knobs, but it's a great seasonal tire for winter (or just offroading, especially on wet ground). Bought here (EU): https://www.electricunicycles.eu/store_t3_category-winter_and_off_road_tyres-sc__12 Red looks fantastic with a black wheel. In its natural element. Snow, mud, etc. Here's a video of the red tire on a V8. Blue doesn't look as good.

@Smoother On second thought, you should start a tire thread (with this info). Then everyone can post links to the tires they found or use. You know, name, picture, short description, link where to buy. We don't have that here yet.

@Smoother Wow, impressive! Thank you. I was just too lazy to put a ruler to my wheel (also, the shell is kind of in the way). 12'' is all I needed to know. Now looking for colored tires. I'd also like some reflective ones (newer bike tires have reflective sidewalls, looks great and makes it safer).

If your msuper V3 started at 97%, it has the same problem that your dioded MSX has - the battery was not nearly full. Not the same as 97% on the KS which is a higher battery charge. So I still maintain the 10% difference can be explained by this. But if you say the 18XL feels more efficient, I believe you. Experience beats theory with range considerations. So I'll shut up about this. - "Thanks again Jason for loaning this to me, let me have some fun with it." I think Jason knew exactly where this would go "Loaning", sure. More like test ride. Probably it will go the same way with the Nikola. I see a pattern how you're buying wheels from now on

Uuuuuuuuuuuuuuuh, nice Good find. I'm tempted. Any 16 inch equivalent? Since the 18 inch MSX counts as 14 inch rim, what would a 16 inch wheel be? 12 inches? Because I see a 12'' option there. I wonder if it fits the ACM or if the clearance is too tight for this tire. Yes!! It should not be nearly as hard as it is to find a nice selection of tires or just simple inner tubes. Somehow these seem to be state secrets indeed.

Probably a "smoother" motor control algorithm with less harsh peaks etc. Maybe that's why GW is doing the same with the Nikola - to not fall behind KS in efficiency/battery usage after they observed that (I'm sure these two companies with their common history eye another very closely).

Marty and 420Wh? He's no scrub

@Unventor He has a 14S.

Wow, I'm surprised. Now finally you can sell your old msuper V3 and still have a backup 18 incher. "Only" 10% difference is in line with the diode of evil in your MSX. So both wheels seem to have the same range under normal circumstances. Chooch-used, indeed. But if the price is good... If I were rich, that's what I'd do. Contact every manufacturer and say "you got something, send one over, here's my CC" *smug smile*. I wondered at first if Marty had somehow spent $20k on wheels. Not quite there yet... or is he? - To stay on topic: I'm sure the next wheel will be a Gotway again. It's called Nikola (or Nicola? Nicole? Something like that.).

You bought one?

They look so small compared to the TO-247 huge blocks, but if they're good (someone knowledgable please tell us), I'm happy with that. Now if the wheel was smaller and cheaper, it would be the perfect 16 incher spec-wise.

Who's right? Original name is with k, but if they use a c... it's their decision after all... who's right? Can't even reliably blame their incompetence now

No, just smaller ones compared to the MSX (there's nothing new in the video compared to the extensive photo disassembly article). But there seem to be 12 (screws in the middle of the board, just like the MSX board which only seems to have different mosfets but is otherwise the same) . I believe the 6 might be the MCM5 (3p instead of 6p battery = half the current = half the mosfets, maybe?) or maybe thast's just a rumor, never seen a picture of an MCM5 board. So basically a 15% downgrade from the MSX, which isn't that bad. (Hardware downgrade, they seem to have a new motor control algorithm so that will do something.)

Anyone know the Tesla and MSX mosfet designations? Not the package names? Trying to find data sheets to compare to. Found 200A rated/nominal/continuous and 600A max for the MSX ones - compared to 170A rated/585A max (???) on the Nikola ones - but not sure if these numbers are correct. If they are, it's not such a big downgrade as it may seem.

According to @EcoDrift's comment on the disassembly video, the mosfets used in the Nikola are called HY3712P and the package seems to be called TO-220. Someone more knowledgable must tell us what that means and how they compare to the TO-247 and the old Tesla level mosfets. Max current seems to be 170A but I really don't know how to properly interpret the data sheet I found: https://datasheet.lcsc.com/szlcsc/HUAYI-HY3712B_C330371.pdf Credit goes to @eddiemoy for asking about the mosfets first

65-160 means they expect us to believe 650Wh goes 65km These ranges are for the different battery sizes. @Kristof Willen That's very accurate!

@EcoDrift Already posted, but thank you guys so much for your videos and detailed photo articles! Prime information on the new wheels, and before others!
