I know my JBD BMS with the Xiaoxiang app has limits of how high and low you can set the parameters, and those limits have changed a bit with the newer version of Xiaoxiang this year. The PC app either doesn't have any limits, or they're so loose I never had a problem setting what I wanted.

Not bad! What's the performance and handling like?

Alrighty. Since your shape is fixed, then we'll go with the previous arrangement I showed above. It will take a couple wires to join together cell group 17, which is broken into two pieces. Of the 100 amp load, the white wire would handle 60 amps, and the black wire 40 amps. Maybe just use 8 gauge w...

If I recall correctly, it's normal for one side of the bottom bracket to be reverse threaded on bikes. I've done the job twice, once each on two different bikes.

This video says it's the drive side that's reverse threaded:

Again, grateful for using a smart BMS. Noticed cell group 4 on my Prancing Pony this time, full after charging while the rest of the groups weren't quite full. During the next ride, group 4 drained sooner than the rest. This suggests one cell was disconnected from the group somehow. I was really rel...

Been biking a lot, with and without family. At first, I was getting disappointed with my battery range. Turns out, I had gotten so used to riding fast while testing limits of my new modifications, I had been just too fast during my trips. Remembered that I like to keep slow enough to listen to natur...

It's probably not the rotor size, especially since that wheel has a much smaller diameter than bike wheels anyway. Read my little review on brake pads here.

Nice trip! I laughed at e-bikes being better than ok I have a dream loop of rails to trails southwest of Madison that I'll do one day, but just with a large battery. In a funny coincidence, it's also 140 miles.

Well... https://lh3.googleusercontent.com/6xjz1KRuvZvAVQwP7yE0XTNL4uEIkz0cdz2CcdpfWgPxPhLFV5ZmBBkDkOA2_HglyJvY-TLRz_SEUKd63k_xJI6LIP3neCTOCLWyjJAGmL_l3RR8uXYmPZS2VIoTTFXuwQEj2GB-quqV4eKq0Z-bdV7F2VQeoITC4XkCU4bHmsXWJINQJDjzQwlzg973AKq2dSwuuOst3PV-btx64MoQOM7guum7xHw62YnsQRZeYL5WHZ28WSXsdamVdZ49MiMXAt...

Mine are only 14s6p, so a different model of JBD BMS. Sometimes I've seen tiny voltage fluctuations when balancing circuits turn on and off, but that's huge. I have sometimes used static balancing, and it does work for me. The balance resistors are very small, and I feel like a 20p pack would take a...

Looking good! So why did you go for 21700? I haven't done the math, but the extra 0.5ah per cell doesn't seem like it will benefit with the extra space needed over packing more MJ1 cells instead. Maybe more amps are what you want?

thunderheart always posts reliable reviews of different battery cells, and advocates buying them directly from Queen Battery via that email in the link. This post is an example. I want to try this for my next batch, but like HK12K says, why are these Korean batteries coming from China? I assume it's...

Just wanted to let you know I'm keeping up to date with this project I did not expect that lawn chair in the background to be part of the build! Are you in kenosha county?

What John said. From what I've seen with my batteries, it's normal for them to all be balanced uniformly at the top of charge. They get out of line a little as the state of charge decreases to empty, but then they all line up again next time they are charged.

Nice BikeE! My friend has one that we've been considering motorizing, in addition to the folding CE Moto ebikes I gave him. Haven't given much thought to a front motor, I have to admit :P What town are you in? https://lh3.googleusercontent.com/17nkaI05zyhP-0Y8BqWAqAkSolVFPpLKVXz0BKFu1p_ZdXaTC9kOgmMI...

Hard to tell what you have there, but it appears to me like a cheap shock, essentially without any damping inside at all. A pogo stick. It definitely does have damping, but only for the top 5mm or so of travel. Once it hits some sort of internal spring, all damping is gone for the bottom 25mm of tr...

I used about 90% battery on both StefEbike with Emmett and the Lynx Sunday. They're both well improved from last year! Excluding the electronics, StefEbike could use a thudbuster seatpost, maybe trigger shifters and that's about all! It feels great on pavement and gravel. The Lynx however, could sti...

All three bikes now have upgraded forks with suspension and disc brake mounts. Like wturber, I've always been able to stop with rim brakes, and my riding is usually just cruising the trails for the scenery. They weren't able to do a good emergency stop though. Since I needed good suspension forks as...

I'm posting this bit about brake pads separately in the hopes that it will show up in google search results. Right now, searching E10.11 vs. B01S barely confirms that they are interchangeable, and I haven't seen any opinion stating which one is better. Well let me state: Shimano B01S are the pads th...

Sorry tmho, I was just responding to serious sam. We're using JBD brand units, and I haven't tried an ANT one yet. It wouldn't surprise me if there was some similar "accessibility" requirements with the ANT software though, as in accessible data to mine for China . You're sure the ANT BMS is all con...

My phone still needs GPS on to have any devices show up on the refresh list. Xiaoxiang V3.1.1013 So, I just tried that version of the app with gps enabled on the phone, and it worked. So all this time it was just not working because I had gps disabled. I guess it's good to know this behavior exists...

Playing games is just going to get all us riding -liking e-bikes banned from most greenways. Agreed, be respectful, as long as they are. I almost had a lyrca crash into me because he didn't obey a stop sign or look over his shoulder for traffic. Yelled "BOO!" into his ear as I passed him right after.

Just go to App settings and disable the "GPS open" toggle switch

Just checked, and "GPS open" was already disabled. Tried enabling it, and don't see any change in behavior. My phone still needs GPS on to have any devices show up on the refresh list. Xiaoxiang V3.1.1013

Thanks for the input guys. I did order the DNM shock that I linked. Their adjustable dampening model (at least on amazon) didn't have a 150mm option, but I'm pretty sure I'll be happy. I'll also try to refurbish the old one just for fun, and see what's going on!

Lucky for me, I'm not too picky about good rebound control yet. Even this Ballistic shock, I wasn't sure just from riding it whether it had functional dampening or not, which is why I was doing the test. I just want a shock with dampening through all of it's travel
