Re: Torque arm for rear hub

If you're using the mid-drive for braking, than that's what needs the torque arm (or rather, it just needs to be very securely installed in general). The hub doesn't need a torque arm for the same reason that you pedaling your single-speed or derailleur bicycle doesn't necessitate a rear hub torque ...

Re: Need help with Cycle Analyst/Phaserunner settings, dies on longer hill climbs.

The plot thickens - the actual battery low voltage cutoff is 36v - I didnt make this pack but checked with my buddy who did. I've set the Cycle Analysts lvc to 42v and watching the display I can see im just about sagging into that at the point the CA shuts down, so I believe its not throttling thin...

Re: Need help with Cycle Analyst/Phaserunner settings, dies on longer hill climbs.

I misremembered exactly how the CA3 handles the LVC. With the CA3, rather than having a rollback start voltage and a rollback end voltage (like the Phaserunner does), it instead simply has that one LVC voltage setting which you found. However, rather than the CA3's LVC being a hard cutoff like the B...

Re: Need help with Cycle Analyst/Phaserunner settings, dies on longer hill climbs.

Basically, if your CA is going blank, that's your battery failing at that point. The CA doesn't blank out until you drop below ~12v. So, it's likely that the problem is your battery's BMS cutting you off, for whatever reason. One potential and likely reason for the BMS to cut you off is that, under ...

Re: 52V / 24Ah triangle battery from Lunacycle is only charging to ~55V | it isn't the charger, already tried to jumpst

As this is a LunaCycle pack, it's more than safe to assume that it has a BMS rather than relying on the charger to detect and protect the cell groups. And indeed, both of the chargers mentioned in the original post are 'dumb' chargers. If one cell group were drained completely, the BMS would have sh...

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...

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.

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.
