  1. The battery swap method works great! I was trying to avoid carrying another battery around, but with a draw-string backpack it was really no trouble at all. Took all of 4-5 minutes to do the swap. Easier and safer than building a battery pack. Here is my next question: When charging a battery not attached to the unit does the battery still balance the cells? Or does it need to be connected for the balancing?
  2. Maybe you are correct. What approach would you suggest to extend battery capacity?
  3. I was thinking about doing a pack with 15 batteries wired in series (15s1p). Question is, is there even a need for bms as it is only one group? Would the cells naturally balance during charging? Or do you need some kind of battery protection? If so, what would work best for this setup?
  4. I was reading another thread about making an external battery. It was talking about a compact BMS like in the picture below. Can anyone tell me where to get something like this? Brand, part number any info would be appreciated.
  5. Finally got to do the downgrade to 1.1.7 I don't have an android, so I borrowed one from a buddy. The app worked great! Just did a 16.75 mile trip. The 1.1.7 firmware is WAAAAAAAY better than 1.4.0 Pushback is much more mild, especially on up hills. Thanks MRN76 for a job well done!
  6. I was able to save a dead battery using this primitive method. The battery was only reading 4 volts. I touched the wires to the battery for about 5 seconds. Did it 3 times and plugged charger into the battery. Battery started flashing red/green. Then after 15-20 minutes went to solid red and fully charged. I think touching the wires to the battery terminals somehow wakes it up. Don't know how or why, but it worked for me.
  7. See this thread for more information https://forum.electricunicycle.org/topic/12816-minipro-intermittently-life-threatening-unsafe-veering-right/
  8. Does anyone know if you could swap motors from a Miniplus to a Minipro?
  9. What do you all make of this? https://rover.ebay.com/rover/0/0/0?mpre=https%3A%2F%2Fwww.ebay.com%2Fulk%2Fitm%2F264265430482
  10. Here is what it looks like. It is under the shark fin on top of the platform. https://www.mini-j.world/mini-tech-en/parts-repair/steering-shaft/#replace
  11. I still think some thing is going on with the hall sensor. Mine did the same spinning while idle. Bouncing the unit around would sometimes stop it. I believe the bouncing would make the cold solder joint re connect for a short time until the next bump or jarring. Reflowing the solder on the hall sensor board fixed it. There are solder connections on both sides of the board.
  12. Does anyone know if the 320 & 260 have the same motors? Or are they different?
  13. I had the exact same problem. It was intermittent and only happened when hitting a bump or crack in a sidewalk. It would just full turn hard to the right. It turned out to be a cold solder joint on the circuit board for the hall sensor. Re-soldering the pins on that board cured the problem. That is where I would check. Hope you find it.
  14. Try putting a ratchet strap around the center of the tire and cinch it down. This will push the edges of the tire against the rim. This worked for me when I had one new tire that would not seat.
  15. I have noticed since I put the 90/65 street tires on my Minipro that when climbing hills I get tilt back earlier than when stock tires were mounted. Not sure why.
  16. I found 50 psi gave a nice ride. 60 psi yielded better mileage. The fenders are not too difficult. Once you figure out the first one, the second one will take 10 minutes.
  17. You will definitely love the larger tires. You will ask yourself why didn't I do this sooner!
  18. I just use it for fun. I like to find new places to cruise around on paved bike paths. I usually travel between 12 to 20 miles per trip. I'm not into extreme speed. Slow and steady and enjoying the sites.
  19. Here is my set-up.... 2 in 1 adjustable handlebar Cell phone holder Small cargo bag Water bottle holder Bose Bluetooth sound system Enlarged and padded foot platform Kick stand 90/65 6.5 Monster street tires More4Mini 63v charger 18-20 mile range (verified with GPS) This thing is a BLAST!
  20. That dual lock stuff look good. Which one did you use, rubber ,acrylic or low profile? I agree with needing the hard surface for the base. I too need good support for my feet.
  21. I like the idea of modular. Do you think that just foam alone will be too flexible?
