Thanks, Scott, for the very helpful instructions page link - the display in my kit (Yose Power C500 it looks like from ebay seller ysbattery-2012) looks like it can be user set:

38418

Just have to be careful not to go over what the components can take (controller 18A for example).

Those controllers can just about manage 18 amps, but not for long periods; however, with the Yose hub motor in normal use, it's not possible to get the current for long periods except when going slowly up long hills because of the way motors and controllers work, so you should be OK.

So I am a little confused now; when you say the motor is giving its all when you are going slow up hill is that 100% of the level 2 55% setting (according to the level table mentioned on page 1 of this thread) or 100% of the maximum the controller is capable of (or limited to)? If the latter, is the table wrong?
My Lishui motor is speed controlled - it will give max amps capable of/limited to in PAS 2 if I go slow enough. So no need to change to PAS 3 or 4, it won’t help more than PAS 2, at that speed. These higher settings will help you to a overall higher speed before cutting out. Very roughly, PAS 2 is at max at maybe 11kmh and slowly reduces until around 16kmh, PAS 3 stops assistance around 24kmh. This is why I don’t have a throttle - the motor kicks in with more amps the slower I go/the more I struggle, but it’s just my personal choice.

I take the KT current control every day over a speed controller, in PAS1 I can achieve max speed of about 21mph without too much current. Thus saving range and power for hills and a longer ride.

I have fitted the KT controller, lcd3 and wiring loom and I am much happier, the bicycle works exactly like my wifes one that was supplied with kt components, the power is the same, taking it up the track behind our house was great, cannot notice any performance difference, I have yet to do a comparison on battery usage as the previous lishui system did seem to use more battery than my wifes kt system, what I really like is the ability to pedal in PAS 1 &2 at whatever speed I want without the controller limiting me, is it worth all the extra expense, I am not sure, if you are happy with a lishui system, use PAS 3 and above - maybe not in my opinion

Glad you are happy with your new KT system. Speed controlled sounds like it might be a bit of an aggressive assist. Max current can be changed on both though, by the looks of it, which is good.

I do worry about changing this max current parameter when my kit arrives though (only if too weak on hills) as I have read my battery has a standard discharge current of 10A and a max of 20A for only 30 seconds, so the battery is already pumping out somewhere between this. I will have to learn about battery technology I think.

I got my Lishui controller and LCD in a kit with the wheel kit, I am thinking of keeping it for a spare, now that I have converted to KT

From my very limited experience people seem to prefer current controlled. I wonder why so many kits have Lishui (Yose and Woosh to name but two). Not cost, I don't think, as they seem to be similarly priced when buying separately. Maybe Lishui make both current and speed controlled?

The early Yosepower kits were all KT controlled AFAIK until about November, December 2019, when they changed from KT to Lishui controllers, my wifes yose bike is KT Controlled My yose bike was lishui controlled but is now KT controlled, I prefer KT controlled

Some how my Lishui display went bad it started to drop in power then after a couple of days There was no power PS: Lishui displays and controllers aren't so easy to buy as there kt counterparts, i hope yose start doing them again as they never put a £20 premium on them.

I have seen Lishui controllers and lcd's on AliExpress.
