  1. Under ideal conditions perhaps, but my experience with cell/packs in general leads me to believe that's not under real-world conditions. Electro-chemical wear still takes place, just "less of it" due to greatly reduced internal heating. (No matter how careful a Tesla car owner is with discharge/charge cycles, the lithium cells aren't going to last 300K miles instead of 80K miles, much less 1.6 million miles--which would be 20x as long.) The numbers they're using are a bit "skewed." If I use 50% LiPo capacity then claim I doubled lifespan because instead of 500 charges it will last 1,000 [
  2. 4.2V was picked as the best longevity/performance mark of the battery by manufacturers, the cells can be charged beyond that but the life decreases more rapidly the higher the voltage. Charging one cell to 80% vs 100% will double the life of the cell. Discharging one cell to 20% vs 0% will double the life of the cell. Balance chargers start balancing at a set voltage which used to be 4.2V, however 4.1V is becoming common to extend cell life. You cannot balance cells by decreasing the charge voltage to the Battery Management System, the BMS must be set to balance at a lower voltage
  3. Sad to hear about your accident, things like that aren't common but they do happen. You could get back on that horse and ride...roll when you fall...
  4. I love it! (and in hot weather that bouncing should be great for making people motion sick)
  5. Seems Veteran hired Gotway's Quality Control manager...probably had to fill the position... Other than a few quality issues I really like the latest offerings from InMotion, KingSong, and Veteran, though it seems a new wheel purchase will wait until 2022. It's unfortunate Gotway's Monster has so many issues, in 2020 that had looked to be a great wheel for tall people. (Maybe BeGoaty can rename it the "Oops, I Broke It Again" edition...)
  6. You have a source for bearings the rest of us need to know about???
  7. I don't know how you older guys do it...I'm 50 with excellent balance, but not on an EUC. I _s-u-c-k_. Badly. I hadn't seen U-Stride's video before, I'm going to try that...kind of like Sit & Be Fit for EUC riders...LOL. Congrats on owning a R-E...that's a project right there! Awesome parts of history.
  8. Too bad parts 3 & 4 were removed....gives me quivers right down my spine ....which isn't saying much for a hedgehog I suppose...
  9. There was a thread on tethers 2 years ago. I have a clothesline leash on my slow wheel, but also bought paracord and snaps for my bigger wheel based on input from ingenious members (it's the "mechanical fuse" concept). I'm not much for safety, but not endangering others makes sense... ...still working on getting that "bigger wheel." I went out with "Gail the wiring harness Gal" from Gotway...I'll never buy one of their products at retail price...ever...
  10. OMg, they did! "Er-ou-eh" (I'm out of "Likes" again or I'd bang that heart button...) "Glue Gun Gary" is still there taking aim...he's running low on supplies though, now that sales are down... Gary, the "Gotway Glue Gun Guy" Gary's younger brother, "Solder Blob Bob" also stayed through the transition. With the company name change Gotway's soldering tech is now known as "Be-goat-ee Bob" (Note: Key-bye Got-away allows me to use their "Americanized" names on public forums)
  11. Looking at the quality of some brands there's no way I'm spending $2,000 (or more) on a unit I know I'll have to take apart and re-assemble because there are 6 screws loose, two missing, seven cold solder joints, a wire pinched, and without me adding reinforcement the $90 housing will crack nearly instantly. Then I can safely start feeding it parts... LOL
  12. I see @ShanesPlanet hasn't changed...LOL. Hey buddy, you shouldn't be worried, you're the one EUC superhero that can run off an impending disaster and laugh about it! ----- I import stuff from China all the time, and if you expect quality...reset your expectations. Generally a company produces good test units (in this case rims), perhaps also a good initial (small) first-run of units (rims), but the first bulk order you place will have 50% (or more) rejects--50% junk. Half of the rest of the units are out of spec, maybe you can use them. Out of the last 1/4 of your order, figure most of
  13. Only because they're commonly sold that way, but rims and motors are completely separate items. Sometimes motors are difficult to install (which is why rims with motors are commonly sold as a single unit), but the Sherman is difficult get the wheel and motor out of to begin with. Example: Gotway Monster rim (& magnets) only (no motor): (That should be a tubeless rim, don't you think? If only they'd add a lip to land the bead.)
  14. Hi everyone, Sorry I've been away, there were a few major family situations that needed my attention and I had to stop hovering for a while. It's now cold in WI (0F = -18C, sometimes colder) so I'm not able to go riding, and could not yet as time does not allow. The new firmware is excellent, no problems whatsoever. When I can get back to having a bit of free time I'll work on some more clear instructions, in the mean time feel confident this firmware is awesome.
  15. There's not a lot of enclosure for that sub, how's it sound? what are you using for an amp?
  16. I leave my home stereo at home...LOL Seriously though, it's hard to get good sound out of a moving, non-enclosed platform. But the Jetsons sounds (by @Dennis ) ought to sound awesome!!!
  17. Do you mean the cost of a Smart BMS? I thought Gotway, and most other EUC manufacturers, don't monitor cells during discharge, only charge. If that's the case @Cody makes a good point. Aren't schottkey diodes $0.28 each out of China, less in bulk?
  18. From @Carbonos post: Monster V3 3108Wh compared to my friends on their Monster V3 84v 2400Wh. Mi riding weight is 100 kg. Last friday we went on a non stop 75km ride with lots of 40 kmh+ riding and my battery was down to 28%. From the EUC Comparison Table: Monster V3 84V: 2400Wh / 25Wh/mi = 96mi (154km) expected range Monster V3 100V: 1845Wh / 25Wh/mi = 74mi (119km) expected range (both match eWheels expected range) From @Carbonos post: 100kg = 220lbs = 15.75 stone 40kph = 25mph 75km = 47mi Expected range of his wheel: 3108Wh / 25Wh/mi = 124mi 3108Wh / 1
  19. Income tax started out as a 1% tax on the richest 1% of the population. Drivers licenses started out as a slip of paper you sent off for in the mail. EUC insurance will be 3x the cost of car insurance due to the risk, and health insurance providers won't cover EUC riders, like with sky-diving. Regulations will be endless, like anything burrocrats get control of, and insurance mandatory. Stay under the radar so you can afford to enjoy wheeling.
  20. I'm sure I'll wait until next year as you're doing. Much the same though, was thinking KS-18XL, MSX, or Monster? Now it's how nice the V11 should be, and by Spring all the bugs should be worked out.
  21. To stop the beeps when it cannot find the wheel, touch the chat bubble in the upper right so it is hollow instead of solid. To exit the program and have it not run in the background, press the BACK button twice, then wait 4 seconds. The first press will display a notification to press the button again to shut down the program. The second press displays the "Good bye!" message and close the resources it is using and exit.
  22. InMotion keeps making me want this wheel more and more. Every time I read the forum there's something more positive that InMotion has done, such as the 2nd charger when they already have a reasonable purchase price. In fact, it's pretty hard to not buy the V11.
  23. The resistor will try to dissipate charge current when cell voltage is above 4.20V. (Note how many cells are in Parallel doesn't matter unless there is more than one BMS, as one resistor R is used per cell group, regardless of the number of cells in the group. This is the problem with basing charger current on what the cells in parallel can handle instead of what the BMS can handle.) P = I x E Power is greatest at the Constant Currant -> Constant Voltage crossover point. If we take the charger to be 84V 2A (note 3A was used be the thread starter, but I'm using a more conservativ
