  1. The marine grease should work fine, far better than Vasoline, just perhaps not so much of it.
  2. They're in India, they have the resources to make anything out of nothing. The creativity there is simply amazing.
  3. That's quite a lot of disjoint things you covered...which I guess could be inferred from the title since muscles don't have memory... Why is there a backpack on the side of the road???
  4. Well, now you have heard of it. Packing too much grease in serves no beneficial purpose and is detrimental beyond a certain point depending on bearing type. This is one of those bearing types. https://www.machinerylubrication.com/Read/28664/dangers-of-overgreasing- https://www.maintworld.com/Applications/The-Three-Mistakes-of-Bearing-Lubrication https://interflonusa.com/4-reasons-over-lubrication-of-bearings-is-bad/
  5. It's not like BeGoaty did an Over-The_Air update request through their Bluetooth app....
  6. Are you aware too much grease in the bearings causes the balls to skate and wear flat spots in them and the races?
  7. Same here on the family and friends, so I respect your position on it. I take some precautions in my own life, like, well, hmmm...I'm careful on stairs--don't want to land at the bottom all busted up with a smashed phone! And I try not to eat real hot food.
  8. I'm glad the EUC World app solved this and you're able to enjoy the wheel. I became a supporter of the app which has so much more functionality than I am currently using--it does everything I ask and more. It works well with a phone, and since I don't want to drop the phone while riding it is also on a watch and works very well. Please help support the development so we continue to have excellent software for our wheels.
  9. Very funny post! I like your sense of humor (and perhaps frustration). Your picture reports as "deleted--that's normal." Now that BeGoaty has acquired the Chinese patent for EUCs it is interesting to see how quality in the industry has become worse at the same time (except Veteran brand that seems to use different ideas).
  10. As a note, the YZPower units seem to have binned (the cheapest on the open market at the time) parts, and slammed-together assembly (whatever-works parts, leads don't fit the hole locations, parts are smushed in on angles, wires aren't in wire runs, no cheap Chinese adhesive--still the wrong thing to use). They don't seem to have power monitoring/filtering/correction that other power supplies have. They did put their name on it, so that's a cut above the floor. The trend in China for the past few years (regarding power supplies) seems to be to take a solid design and put really cheap tran
  11. The good thing is the KingSong shock and InMotion bearings are probably both off-the-shelf parts in China (meaning cheap replacements). From my non-EUC Chinese bearing experience, cleaning all the cheap OEM lube off them and putting good lube in, then cleaning & lubing regularly generally makes them last a long time. On gas shocks (air pistons) I use Magnalube-G PTFE Grease to keep quality air pistons in service. $3,000 for a Sherman though--and then the rim needs to be rolled to hold the tire. Eh, I'll wait until Veteran figures out a suspension and OTA updates. They
  12. Other than marketing I haven't seen reviews on these. I'd think for the price they'd be in huge demand if they did 75% as well as they claimed they would. They made some bold claims, and from an Engineering standpoint things didn't seem to match up with what they were saying. At some point some company is going to pull this off, perhaps it will be them if they're not there yet. Surely there's market interest. EyeLights SAS made Captain Rider software that didn't review well which is worrysome.
  13. @ShanesPlanetI said way back when Kingsong subbed out their Fox shock for a knockoff that the suspension is going to be weak. There's no way a tiny mono shock can take a beating like that one does without being a quality part. And you bought one anyway. Who'd have thought InMotion was going to have bearing issues though? Runs counter to the company name...
  14. Quickly cancel your order! When you feel better you'll realize how unclear that line of thinking was!!!!
  15. I'm wrong, the Chargery reportedly uses 4.20V as do other EUC chargers. Simple, cheap, light, and fairly safe. Fast--no, but "faster." From the information I've seen I would guess the Veteran BMS does seem to stop the charge cycle to check the battery state and if the battery test comes back "sane" the BMS continues charging the battery, which works fine with a standard power supply that doesn't care about the lack of current draw and continues supplying power as needed. The Chargery, from the manufacturer's site, seems to be a smart charger in the respect that when the charger dete
  16. Thank you @mrelwoodand @Chriull, I stand corrected and learned more about EUC charging. Note the voltage while charging should be measured during the constant-voltage phase, otherwise (depending on the charger) the standby voltage can be a bit misleading, at least on the chargers I've used, depending on how smart the charger is and how well the output is filtered. There's room for advancements in EUC charging...obviously the current flow is going to dictate the charge rate while V is less than Vmax, so a faster charge during the Constant Current phase is dependent on the maximum cur
  17. That's one of my concerns with the Veteran Sherman, the quality of it and many other wheels isn't steller from the end of 2020 forward, while the speed we're asking for is. 44 vs 27 is a 60% speed increase and a bunch more Kenetic Energy given velocity is squared. KE = ((m)(v^2)) /2
  18. The V in fast chargers tends to be higher. Safe maximum (and minimum) voltage on a lithium-based cell depends on that particular cell's chemistry, but typically it's 4.35V. The lifespan at 4.35V is only about 20 charges, sometimes 10, again depending on chemistry. The lifespan of the same cell at 4.20V tends to be 500 charges, and at 4.1V around 1,000 charges--but that's highly dependent on chemistry and manufacturing process. Most "decent" cells will last 1,000 charges at 4.0V maximum. That's resting voltage though. Cells have something called "surface charge" where a small percent
  19. We've all seen it, what you're told before the sale doesn't quite match the product you own after the sale. Maybe the Engineers stretch the truth a little in their reports to Management, and Management does some creative rounding for the presentation to the Board, and the Marketing department lives on a whole different planet. When does it become a lie? I deal with "cheap shit from China" on a daily basis, and they've made exaggeration an art form. Look at the range estimates for EUCs and you know what I mean. People have guessed the Chinese find the lightest person around, have them putt
  20. Some high-end lithium BMS units I've encountered stop the charge cycle to check the battery state and if the battery test comes back "sane" the BMS continues charging the battery. Since a power supply doesn't care about the lack of current draw it continues supplying power as needed. A smart charger is a bit different: when the charger detects output current has fallen below a certain setting it stops the charge to prevent trickle charging the battery, which is harmful to lithium packs. The Chargery has this feature, so a "sanity check" by the BMS will cause the Chargery to stop charging
  21. I agree with @mrelwood on why: From experience, new cells no longer go through multiple charge/discharge cycles at the factory so they can be matched with similar cells, the practical reason being the cell assembly line is moving so fast (due to market competition) the paste thickness/uniformity isn't very uniform, so matched cells will go out of balance with use anyway. Paste thickness tolerance is incredibly tight, cell manufacturing machines wear quickly, and constantly upgrading bearings and the down-time associated with doing so is costly, so it's not done as long as the cells are
  22. Though the V8F is half the price, in stock, and just over 1/2 the weight of the V11... ...plus they're really reliable and owners love them... (and they're available on the Private Sales (secondhand) forum for even less...)
  23. Your reasoning is correct and cells will be fine with that. You're not over-heating the cells nor over-straining the balancing circuitry during fast charging, you're using the normal speed charger during the balancing phase, and you're not running the packs down enough to hit minimum voltage on any of the [newer] cells. As the cells age this might become an issue, but for now you should be fine. Do note with fast-charging the first 80% (constant current phase) goes faster than normal, but the last 20% of the charge (constant voltage phase) and balancing goes slower. (Time is saved over-al
  24. If you gear up with the mentality you're going to unexpectedly go down at 50MPH, pile up into a curb, then get hit by a land torpedo, you'll save a lot on hospital bills. We tend to plan optimistically, and eventually the unforseen happens... I'm not a safety snob (rather far from it). Spending time here with members who shared their unfortunate incidents (many at slow speeds) clued me in to what I don't know. Quality gear is way cheaper than bodily repairs.
  25. Reminder: It's not just what the cells can take, it's also the heat the balancing circuitry can/can't dissipate.
