36v 500w tsdz2 on this bike, recent trip to Tetons https://forums.electricbikereview.com/attachments/img_20260608_140147811_hdr-jpg.211250/

I see aliexpress currently has sale on TSDZ2B, shipped from US, $227 for 36v version with most expensive display. That seems like an unbeatable price. OP have you made a decision or just thinking?

He probably just meant control/display rather than controller his is the very old version, I got that with my first one but replaced it with smaller integrated display/control. If this is too difficult for the OP to undertake then, as I posted before, a Keyde rear hub motor which has an...

There are plenty of youtube videos regarding installation of a bottom braket motor onto a trike. Here's one for an older model Tongsheng TSDZ2, there's now a newer model called TSDZ2B which probably installs the same, they are torque sensing. You can decide for yourself if you're capable but I...

You might want to look into a Keyde hub motor. I have a standard axle S110 with a 135mm O.L.D. but they also make a 142mm thru axle version. Simplest possible installation as the controller is built into the hub, only one wire to battery and a wireless (or wired option if you prefer)...

I didn't ride as much as I would have hoped because of weather but the BtrPower battery did well and maintained 40v without sag for the 11+ miles that I used it.

Not a bad idea given the history of this battery. Just yesterday I replaced the Anderson connectors that had been on it with xt60. I thought I was being careful but the Harbor Freight "helping hands" holder for the wires and xt60 slipped shorting the wires for an instant. Upside is that up...

I'm going to charge this battery out on the driveway (in the shade) which is how I usually charge my cheap Amazon sourced batteries. Yamaha batteries I charge in the house but not without monitoring.

I only took it for a short spin so far, the display didn't show any voltage sag, only a couple millivolts while riding. Planning to fully charge and see how it does riding up my road (400 ft elevation gain/mile). I won't be surprised if the results aren't what I hope they will be but one can hope.

Hopefully I didn't just put it in storage fully charged but I wouldn't put it past me - I often feel sorry for the future me. And I do try to follow the best practices but when it comes down to it I'm not that diligent, obviously. The battery is a widely panned BtrPower so it probably doesn't...

Here's another anecdote: 36v BtrPower battery several years old, unused/uncharged since ~'23. I dug it out because I'm planning on some rails to trails riding, taking my '06 Walmart Schwinn with 6-7 year old TSDZ2 (because it has walk assist which BH unexplainably blocked on my Yamaha powered...

Does Li-ion battery degredation results in lower full charge voltage or reduced amp/hour capacityor both? While I try to not leave batteries used on ebikes fully charged for more than a few days I've certainly left them fully charged for much longer than that, sometimes months. Despite this...

I loved my V7 but it was too much of a bike for me so it had to go. Prior to the V7 I had a TW200 that I took on the ferry from Bellingham WA to Haynes AK then rode 2600 miles back home including Banff, also a 170cc scooter bought sight unseen (had never even been within 100 yards of a scooter...
