So I've been using a KT-LCD3 myself, but have found much here to useful and informative. While I'm mostly happy with my settings currently, AND with what I've learned in trial & error with notes, I still have a few minor issues.

One is that "battery meter",... and it's not something I rely on in any way, so it's somewhat minor to me! Wasn't exactly easy to set up what I got in the first place! And I'm not terribly certain of all my exact settings right now, but I'm generally satisfied,... sorta. I generally use a "battery chart" of relational voltages to capacity remaining and find it far more reliable than the "battery meter", even if a bit inconvenient.

1500w hub motor on 29" wheel
52V 11.5Ah battery on 48V 40A controller

Now, strange as it may sound to some,.... I use the "cruise" option a lot. But it won't set below 25kph/15.5mph min., and I would much prefer a setting of say 15-20kph/10-12mph. Any way to maybe alter this min.???

You see, at max I've hit 40mph,.... much more than I need or should be cruisin' about without "trouble". So I have a max speed setting of 30mph set, and I generally watch that I never exceed 20mph, unless I'm outa town on clear open roads and then 30mph is my comfortable max. I think I currently have a max current setting, but occasionally I'll have that at half setting,... 20amps. Minimum pas (1) setting still gives me about 22kph/14mph or so, and a cadence that I can jus BARELY overrun. But this lets me have the torque, power, and speed I occasionally need "right at hand" (via throttle) to avoid "situations", but I'd like to mostly pedal at "bicycle" speeds usefully, and without pausing and coasting to maintain that 15-20kph/10-12mph for "proper city use" (lol!!!) and to extend "mileage".

Any way to lower "cruise" settings????

If you just press the button twice it will display the voltage.
Anyone know if the time of day can be set/shown with it?

Bump, since this little display is very confusing to me and others .
My first conversion ... ... 1#p1077497

It's 2018 already, lets get some real , improved e-bike / e-velomobile / e-motorcycle designs .

Hi there,

Does all controllers support regen function?
I have this SLCD-3 that support regen but i am not sure regarding the controller.
If regen is possible does harm anyhow the batteries??

Thanks, a lot of useful info here!

Hi, my motor has these writings on it
And the p1 setting is 87. Anyone knows if it is the correct one? That's how I bought it.

Hi guys

In the thread below I explain the use of parameter P1 on Q100/S-LCD3 display.
I expect it to be the same on q128 and other motors/LCDs


Sincerely yours
