Re: bluetooth BMS?

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.

Re: Help building battery triangle 20s10p

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...

Re: Mongoose Envoy Cargo BBSHD Jumbo Shark

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:

Re: StefEbike for my wonderful disabled wife

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...

Re: StefEbike for my wonderful disabled wife

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...

Re: all season e-bike (second build, Fattest)

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.

Re: Around the world on a solar ebike

Nice trip! I laughed at e-bikes being better than ok :D 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.

Re: bluetooth BMS?

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...

Re: PWD's Rocky Mountain Element - refresh

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.

Re: 72v li-ion battery problems

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.

Re: Bad suspension - poor design or just in disrepair?

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...

Re: StefEbike for my wonderful disabled wife

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.

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.

Re: Got fried by Col. Sanders today. eBike vs pedal

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.

Re: Bad suspension - poor design or just in disrepair?

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!

Re: Bad suspension - poor design or just in disrepair?

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 :)
