You can also just take a sine wave controller, does that KT controller work well and does it drive without stuttering? I just wanted to know if it was possible to build hall sensors yourself.

Yes, The one from Ali express (48V 500W 40mm height), works well, if you are new to the scoot repairs, this specific display (add on purchase) can help you determine (narrow) down the fault (in my case it's throttle error (which is fixed) as shown on the display). It does work without shuttering from my best knowledge, sometime it does rattles but it's rare but give it a quick kick and it works and even sound just like the ones on the street. You can build hall sensors yourself from the other guides listed on the article but it may not be worth the hassle, no reason to rebuild the hall sensor if the wheel may need to be replaced with another wheel, or something else need replacement. So far the Lim S Gen4 seated works well, the mini 36v battery can get me places, but not very far. 2 of them plus a charger is needed for long distances.

I have placed those articles about placing Hall sensors myself, I now use a 52 volt battery myself and go almost 50 km per hour, does that KT controller fit in it or do you have to grind it?

That new big battery, I think it's a 14s, everything points to this.
When I start counting, do I always end up with blocks of 12 and not 14? Who knows more about this?

They're 3x13 in a V pattern in mine. 46.8V 16.75Ah

No, now I know it
a 14S, 52 volt Battery. I have already replaced the BMS 14S and it works perfectly.
