    DIY powerwall 14s100p 18650s DIYBMSv4 currently running

    Changing to LifeP04 280ah 16s, so most likely will sell the existing powerwall. Most of these batteries came from medical modems which I took apart and built these strings over several months. All batteries were capacity tested and average 2700 ma for the whole pack. I sorted these in groups...

    Generic-Chinese-Bluetooth-BMS-communication-protocol

    I know I'm late to this party, but. I just purchased one of these BMSs (without their blueTooth module) from Battery Hookup for 16s lifeP04 DIY build. I do Arduino/ESP32 stuff, so have a bluetooth module. My question: What or how to determine the pinout for BlueTooth module connection...

    Great work! I like the new remote 3D design. On the new documentation page the link "How to flash bootloader on dongle" is broken. Link is under "Step by Step Instructions".

    As an mbrusa user, I am very happy with my last configuration/flash ebike and motor wise. Having the wireless and ease of display on my phone would certainly be a PLUS! I really noticed the cadence giving assist way up high probably near 120 or so, no way to measure at the time. Very happy...

    Tsdz2 firmware open source adapted to vlcd5, vlcd6 and xh18

    Ride today, finally after much bad WX and other stuff getting in the way. Really nice, never got above level 2, level 1 mostly running easily 18mph, going through top 4 gears for hills. 62c high temp. Really great, not sure I want to change anything at this point. Thanks to all who put in...

    Bike was donated by a close friend, it is a "Specialized Fuse" with 3" tubeless tires and drop seat (the lever next to the keypad). I do have to reach for the keypad, could move the drop seat control over to right and move keypad closer, brake clamp is very minimal.

    I do have PLA, thanks for the printing tips. I will save the PETG for tough outdoors or in the car stuff. Do you use a release? I am on Ender 5 Pro with magnetic base, which is fine for PLA, but about to wear it out removing the PETG.

    Printing today, still steep learning curve even just slicing. PETG is tough and sorta hard to print, but starting to get it I think. Switched from .4 head to .6, which made it somewhat easier. 250c print head and 70c bed. Still a little rough but close, great job on the design casainho!

    My 3D printer came in last week. I'm learning Cura, Octoprint, free cad also. Some very good youtube tutorials 7 months old, helps a lot. Also HOVER over the mouse at bottom of screen in free cad and see what controls what. I'm at the point of trying to calibrate the printer as it is off too...

    I thought that the blue light would be flashing for DFU upload. I did have the blinking red before the boot loader flash, but nothing after.

    Hardware temperature control tsdz2

    May do that on next flash, set the minimum to 70c on this flash. Also took my motor out and sanded down the insert .040" or so, and this time thermal paste that just came in the mail. Applied thermal paste to the half round sleeve inside and out where it touches the motor and housing. Made...

    We have a "HOTSPOT" so back on internet via 5G. Yes, I can see "TSDZ2_DFU" in both devices. (Mac and Samsung) 1. I believe it was "TSDZ2_wireless_ota_update-v0.6.0.zip" 2. Tried with "NRF Connect" on mac, then samsung "NRF Connect". Going to your link now to sort.
