Re: Controller recommendation for good PAS experience

Compuatic, My first kit included one of those 'DC Moto' controllers and SW900 displays. (DC Moto is not KT.) Yes, the PAS settings with this setup is harsh. I liked the look and features of the KT-LCD3 display so I ordered one thinking it would work with the DC Moto controller. Unfortunately it didn...

Re: PSWPower Sinewave Controller w/ regen braking

davidserin, I haven't been on here in a while, but will give my 2 cents. Secondly, you're probably more technically inclined than me, but I do have a KT controller with the KT-LCD3, so here goes. 1. As I recall PS Power offers the same products as KT (just rebranded). 2. I'm pretty sure you need the...

Re: Ebike brakes

Hi guys, For me, initially, I could not get the brake cables off my existing levers to fit the typical e-brake levers you get with a China ebike kit; plus, they are pretty big and ugly. So d8veh suggested using the reed switch from a generic speedometer. This is what I did: https://endless-sphere.co...

Re: What ah should I expect to get running a 48v 10.5ah battery

Hey guys, to update. For the first year I owned a CA, I was calibrating the RShunt value to match my KT-LCD3 display as I assumed the latter was accurate. After doing so (at the ~4.5 mOhms), I was disappointed in my battery pack's output of ~7Ah as mentioned above. Well, after getting a pretty accur...

Re: Watt or Ah Meter Options?

Hey guys, good to hear from the dogman and d8veh. Sorry, don't get on here much anymore. Apparently OP does not want to use a KT display (I think the KT-LCD3 is great, after the CA). Actually, the meter I posted does maintain cumulated Wh until you manually reset it by a button. So that's good. I re...

Re: Watt or Ah Meter Options?

I hear you. First thing though, I think the S12S is a KT controller, right? If so, I think you need to run one of their displays for the controller to work. In any case, I tried one those generic ebay 150A power meters (nice size, form factor). They're not that accurate and I think many of them can'...

Re: KTLCD3 assistance fine tuning.

BlueseaBob, I looked at the manual and think you want to tweak: C5 (current setting (what d8veh mentions)): actually, 03 will halve whatever current your system has - so a lot lower than just 5 amps. C14 ("power assist tuning"): I too desired less power with my PAS, so this is set to 1. C1 ("power a...

Re: Wattage on SW900 Display?

I think those kits/displays are marketed towards 48v and 20 amp controllers (ie, approx. 1000w) so the display only goes to 999 watts. If you're drawing more than 20 amps on a full battery, perhaps you've tripped the watt meter, so 999 + 200 will only show 200 watts. That may also be why while on a ...

Yes, you can set the nominal battery voltage (36v or 48v) with the SW-900 as I recall with parameter P03. Oddly, although the KT-LCD3 is more configurab...

Re: Accelerator (throttle) does not work

If you have P4=0 and C4=0, the accelerator/throttle won't work when the PAS indicator shows 0. Press the ^ button to set the PAS indicator between 1 -5. Your zero start should work. Further, if you set C4=3 you will get a zero start even when the PAS indicator shows 0. I suggest installing the PAS. ...
