Re: RadPowerBike RadCity Commuter

Try it. Prove it to yourself if you have a regular controller. High powered controller’s can be pushed higher to hide the problem. We notice it everytime I forget to top off the pressures. It’s a different bike at low pressure with a direct drive radcity hub which is the main one with a problem tha...

Re: Newbie regen question

Re: Charging Battery Through Output

I have a 36V battery that apparently has a problem with the "input" connector, that is there's no indication it's being charged. However, it can be charged through the "output" connector. Is this a problem? Depends on what's wrong with the input connector and how it's wired to t...

Re: New upgrade, several LCD functions not working properly!?!?

If you're swapping back and forth between 2 displays, with one working and the other not, with no other changes, I think it pretty safe to assume one of the displays is defective. Agreed, yep thats exactly what I ended up doing. :D Whether its the built-in cabling on that unit or something else, so...

What case? Alan provided a lot of data, and you provided some subjective descriptions. What are the values for "zooms" and "steep"?

Re: Motor cutouts at high load on new battery with *less* voltage sag than previous battery

When i was running the original battery the voltage drop at full charge was around 3.5v (from 58.8v to 55.3v) at full acceleration and everything was fine. Now when i am running the bigger battery, the voltage drop is max 2v (from 58.8v to 56.8 - 57v), and this causes a problem : when the battery i...

So everything here is new, controller and display (LCD). There is only the "green" connector for that and then the black one for the throttle, right? Today I will test using another throttle I have and see if that works.
Were the display and controller come as a set?

Can't tell what you've tried since you don't appear to be approaching this methodically. Maybe you did this, but plug everything back in, push the switch that usually turns on the bike, then check all of the throttle wire voltages to ground, using the pin/needle trick.

Re: Right settings for regenerative charge ?

It means that the BMS would not be limiting current during regen, so you have to protect the battery yourself by choosing a reasonable charging current, based on the cell specs and pack configuration.

The battery from your link appears to have an XLR connector for charging, and separate Anderson connectors for discharging.
