Re: HELP! Jerky driving with Grin All Axle hub motor

Then the switch is just providing power tot he CA, as it doesnt' have an on/off switch wire, just main power input. This isn't quite correct, for the newer Phaserunners/Baserunners paired with the newer CA3's with the waterproof connector and MF switch. In these units, the power button on the MFswi...

Re: Two throttles in parallel?

I'm using two hall throttles, simply wired in parallel (all 3 wires), to a Cycle Analyst 3. The Cycle Analyst simply sees the higher of the two signal voltage inputs. So, for example, if I set one throttle to 2.5v and the other remains at rest (around 0.85v, as is typical for hall throttles), the CA...

Based on the numbers you've provided, your cell voltages are as follows. After charging: 1. 4.0v 2. 4.1v 3. 4.0v 4. 4.0v 5. 4....

Re: Compact Field Oriented Controller, ASI + Grin, limited run

But you can use the PR in sensored-start / sensorless-run mode, so if you do have sensors in the motor they will help you startup, then be ignored afterward. This is the best mode as long as it falls back to full sensorless mode if a sensor stops working (that, I don't know). Just confirming, the P...

Re: 52v battery on 36/48v controller doesn't work.

Sounds like you might not be making a good/consistent connection between the 52v battery and the controller.

51.1v is well within the normal voltage range for a 48v battery as well, so whatever the problem is, it likely has nothing to do with the battery being 52v.

Would that mean then that the motor/contoller/battery is seeing full power with no ca power limits when the throttle is directly to the controller? Yes. The CA3 imposes its limits by altering the throttle signal from CA to controller. It can't do that if it's not sitting between the throttle and th...

Re: Bike Throttle Replacement Search

The 3 throttle wires will be 5v+, negative, and signal. The throttle runs on 5v, not 36v.

If your 4th wire carries 36v, than that's likely specifically for a battery meter, and hooking that up to the throttle 5v+ line will just fry your throttle.

The Baserunner installs into the battery cradle, not into the battery itself. You can move your Hailong battery around to other bikes, as long as they've got the compatible cradle.

Re: Why are geared motors worse than direct drive for climbing hills?

The point of geared hub motors is to pack the power and torque into a smaller, lighter package. Unfortunately, for a variety of reasons (less mass to soak up heat, much poorer heat transfer path due to the internal gearing), geared motors tend to heat up more, and overheat faster than direct-drive m...

But if the CA send no speed values to the controller, then this isn't a solution.
There is no data communication between the CA and the controller at all. The only thing the CA sends back to the controller is a simple throttle signal with a configurable voltage range.
