Mokwheel Basalt 2023 Wiring & Mapping

[MrBurgundy]

Just offering some details for this group in order to better understand questions related to Mokwheel owners. These details may help to troubleshoot the Basalt.
NOTE: All references to wire connector numbering is clockwise from Alignment Tab in numerical order see Img. 1284. Mapping Example: 3-5 referencing "From" - "To" as per numbering order above.

1) Battery img1260,61 Model CDL4820 LI 19.6 AH, 924.924 Wh, 47.19 VDC
1a) 6 Post Battery Base img 1287,1293
Terminal Mapping
#1,4 Thin Gauge to/from solar charge port
#2,5 (2-Pos) (5- Neg) to Controller and Solar Charge Port
#3,6 Thin Gauge to/from Controller

2) Display said to be M5 img 1303, 5-Button hardwired to Display functions: Power, Up+Down Display Navigation, Headlight, Horn. Two Male cables (Yellow 3 pin, Green 6 pin)

3) Handlebar Harness group img 1312: (Red 2 pin x2 Interchangeable Brake Contacts) (Green 5 Pin Display fem), (Yellow 3 Pin Display fem), (Yellow 3 pin Throttle Male), (Yellow 3 Pin Headlight short fem) to single 10 pin at bottom bracket into Controller
Mapping From:
3a) Red Brake to Controller (1-7, 2-8)
3b) Green Display to Controller (1-3, 2-2, 3-4, 4-8, 5-5 )
3c) Yellow Display to Controller (1-nil, 2-9, 3-5 )
3d Yellow Throttle to Controller ( 1-10, 2-8, 3-1 )
3e) Yellow HEadlight to Controller (1-nil, 2-8, 3-9 )

4) Controller: two groups of three img1283. Group 1: Red/Black from Battery, 10 Pin male to display img 1284, 4 Pin to Brake/Tail light. Group 2: 2 pin Brown/Blue from Battery, 6 Pin from Torque Sensor Img 1285, 3 Pin to Motor
Harness Pin Mapping Img 1284:

5) Solar Panel Charge Port img 1298,1296 : Pos/Neg from Battery, White/Red from battery
6) Motor said to be rebranded Bafang, possibly H550 img 1305,1306
7) Bike Overall img 1309
8) Motor removed from Hub showing stamped markings. img 1327,29,30
Hope this helps someone out down the road.

Hey, thanks so much for this post!

I'm looking to use a buck transformer to step down the output on the "Solar connector". Did you test with a multimeter that those +- connectors are referenced directly to the battery, or is the controller involved?

My hope is to use a modified connector to mate with this and power USB devices from that port using the Buck transformer.

Thoughts on that?

The Pos and Neg from the battery base are connected in parallel to both the controller and charge port. That is about all I can tell you. See Image 1293

Hello, I like your idea totally!!! Would you mind posting your final results, links, and a final diagram of where you sourced everything from? I have no experience with the Basalt being by first off the shelve bike. I am a little familiar with DC and soldering so when you mentioned installing a buck I knew exactly what you were up to. And already disassembled parts to see how much room was in the tube. Are you going to go for a fast charge auto voltage sensing modular like many of the newer Apple products require but automatically step down to old USB 2.0 charging standards? I guess the components used and installed are the most important above the ability to charge an iPhone, I would love to have a factory-looking waterproof USB C outlet in the frame near the top.

"My hope is to use a modified connector to mate with this and power USB devices from that port using the Buck transformer"

My idea would be to take yours but solder to those tabs and run wire up inside to the top of the bar and have a factory-looking weatherproof female plug right in the frame. I'm sure this has been done on custom-made bikes and will be a standard port on bikes in the near future.
Any readers who would like to direct me to factory models already doing this? Appreciated.
That would sure save having to run cables from an outlet to recharge all of the attachments I mounted to a secondary accessory bar I have riding high, proud of the handlebars about 2x the length of normal the local steel shop cut me to run from brake to brake without interfering, it's a big bike so I figured the 6" long blinding off road led headlight was worth it in addition to the stock on the basket. Absolutely, new to Ebikes and forums but I own this bike and would like a few mods. Feel free to advise me if I didn't respond correctly and need a new thread or anything like that.
Thanks
