So I found an almost complete hubmotor wheel / controller setup at Goodwill today.
--26" fatbike wheel
--Bafang 8fun geared hubmotor BFSWX02 48v500w(13)
with gear cluster and 180mm disc rotor
--controller LM1605-066-J, 48v 18A / 9A, 500w
--961 LCD (antiscratch plastic still on it)
--halfgrip throttle with half-bar grip and full grip for other side (both appear unused)
--PAS 12-magnet ring
--torque-arm kit (unopened)
--wiring harness with partly JSTs and partly Higos.
--No ebrakes, no PAS sensor, no battery or battery holder.
Had to improvise a test setup, as I have nothing at hand with wide enough dropouts in the rear for a fatbike motor, so I used some short (pitbike?) crappy forks in a heavy steel cruiser frame (to counter the wheel weight) as a test stand. I think the bent Luna fatbike fork might also work but these were on top of the "junk" pile so they got used.
Powered it on with an old 13s Luna battery kept around for testing stuff like this, and it does operate off-ground, until it reaches 9.5mph, then it shuts down, and stays shutdown for a while, before it will respond to PAS or throttle again. (Used a PAS sensor from the old Fusin kit). If I keep throttle down below that speed, it'll keep running as long as I care to do it, AFAICT.
Found the C961 LCD manual in a few places, and verified the settings all appear to be correct; speed limit is maxed at 40km/h (which should be around 25mph, not 9.5).
The only setting I can't verify is one called (IIRC) "hl 4", whcih will go up to I think 60; this comes up before the timeout setting but isn't in any of the manuals for the 961 I can find.
The speed sensor is working or I wouldn't see the MPH on the display.
(some systems stop if they don't get a speed signal).
There are no error codes coming up on the display. I can force an error by disconnecting the hall cable, so I can see how they would come up if there were any happening.
Current draw is normal.
There are five unused connectors, all 2-pin JSTs. One pair are black and white wires, the other pair are black and gray, and then there's a single black and red. Comparing this to another controller I've had pics of from a Rad fatbike, the gray wires probably connect to the ebrake levers. Don't know about the white or red ones; they're not in the pics of the Rad controller, or on the Fusin.
Probably have to open it up to check where those wires go.
Any ideas on why it is shutting down after reaching 9.5mph?
I verified the motor itself works (offground) by using an old LiShui controller and Kingmeter SW-LCD display. Took a bit of wire swapping of the cntroller's hall connector to match the 8fun's hall output, but once that was done it ran fine, at anythng up to the 25mph or so max speed that controller allows.
Second question: I know there are Kingmeter SW-LCD manuals around here somewhere, but I can't find them. I can only find the SW900 series, and that doesnt' match the old SW-LCD that I have. It looks similar, and most of it is the same, but if I hold down all the buttons I get a screen with "Prog 1310" (IIRC) on it, and haven't found a secret combination of button presses to get past that into anything else, and then ti times out after some seconds and goes bakc to the main display.
Anybody know what that display might mean, or if there are deeper menus for this SW-LCD like there are for the SW900 LCD?
