Some controllers require reconfiguring via the LCD panel depending on the type of PAS sensor used. What controller/LCD panel do you have? What type of PAS sensor are you fitting and how many magnets?

Red - 5V Green - Signal Yellow - Ground EDIT: I assume you are describing a pair of connectors (sensor & controller). If not, please ignore the above and provide further info.

Hear hear! There's no way around the fact that good customer service & support costs money. Cheap(er) prices usually means means corners have to be cut. Be careful not to be penny wise and pound foolish.

I'm not sure how you managed to get the computer to communicate with the controller previously without it being switched on as claimed, but it's good to hear that you got it sorted in the end.

The following link contains the best explanation I've found for the BBSXX programming options: https://electricbike-blog.com/2015/06/26/a-hackers-guide-to-programming-the-bbs02/

It sounds as if the controller is powered up okay, so don't worry about the ignition wire right now. Are you able to take a voltage reading from between the red & black hall wires on the controller? This will confirm that the 5V regulator is functioning correctly and is able to provide the...

'Current' throttle controls battery current (torque) in direct proportion to the throttle position. 'Speed' throttle controls motor speed in direct proportion to the throttle position. In theory, speed throttle sounds a good idea, but in practice, the controller applies full power until the...

You won't be able to evaluate the 'current' setting unless the wheel is fully loaded. The reason you're seeing the wheel spin up to full speed with only a little throttle input is because at no-load, there's very little force to overcome.

Possibly a silly question, but is the controller switched on? Have you connected the ignition wire to battery positive? Assuming you do have the controller switched on, are you able to take a voltage reading between the red and black hall wires?

The controller doesn't know, but the sensor does. Inside a 3-wire dual hall PAS sensor is a pair of hall sensors spaced much closer together than the magnet spacing and some basic logic processing circuitry. This is used to calculate the direction of movement and limit the output to a single...

What happens when you connect the Sabvoton to your computer and run the hall angle test? Do you see any motor movement? Do you ever see an updated hall angle number?

Although a suitable alternative, that isn't the same connector the OP is searching for. As mentioned above, search for 'motorcycle connector' and you'll find what you need.

Are you able to post a photo of the connector, or a link to one?

What about using something like this to detect the chainring teeth: https://www.ebay.co.uk/itm/M18-8mm-DC-5V-NPN-NO-LJ18A3-8-Z-BX-5V-Inductive-Proximity-Sensor-Switch/113223650675?hash=item1a5ca7cd73:g:pFkAAOSwPPNbhRS3:rk:3:pf:0 It works on a 5V input and detects aluminium and iron from a...

Overlooking the issues of connecting your packs in series for one moment, I doubt that your Carrera battery would be able to sustain the continuous output required to reach the sort of speed increase you are talking about. What is the other battery pack that you own?

Yes, current increases during flux weakening in addition to the extra current required to reach those higher speeds. Field weakening definitely requires a stiff battery.

The beauty of field weakening is that efficiency is only affected whilst the magnetic flux is weakened. Below these speeds, the controller behaves as normal. Swapping the motor for a higher kV motor, or raising the system voltage would move the efficiency curve across the board.

I can personally recommend these, which I've been using for a number of years without any issues. They're currently priced £58.99, which makes them a bargain in my book...

FYI, this is the cheapest way to obtain a Phaserunner that I am currently aware of - £229.00 delivered, UK stock: https://electroncycles.co.uk/product/grin-phaserunner-electric-bike-field-oriented-waterproof-motor-controller-30v-90v-50a/

No, I haven't tried one myself, but I've only heard good things about them. My biggest issue with the Phaserunner is the 90A peak phase current limit, far lower than I tend to run nowadays. I'd consider one for use with my BBSHD FS build if the controller ever fails though. I've had my eye on...
