While waiting for controller/hall sensor tester in order to troubleshoot my electric fat cruiser, I am starting my list for a board tracker replica.
As I already have a 48V/12Ah battery/charger which is quite strong, I want to use this base as a build start.
1. For an average 36V250W motor can I run a 48V/1000W controller on it? I plan on putting ATF oil inside it for better cooling and usage should be 90% on flat with some peaks of 800-900W (maybe when I just want to overtake another cyclist on the street). As I am 220lbs, start should be with pedals or just a push and max speed should not be more than 30km/h - 19km/h. I read around here that this is douable, but... Well, I don't like burning stuff and another confirmation is good. Plus, I want to keep the weight as low as possible and these 36V/250W motors are quite compact and light.
2. I plan on buying a second hand 36V motor, I can get them quite cheap in my country as people are very careless about their ebikes and no one really knows how to repair them. For example:

Seems to have some issues with the wiring, needs to be checked inside, but overall quite ok. It's a BAFANG 36V250W so pretty reliabe/strong.
Any type of Hall controller will work on it? Or should I just go with one without Hall sensors?
I am asking this because I saw that there is a multitude of hall chips inside the motors (even for the same motor) and I don't know if they are compatible with different controllers.
What I think it would work:

3. Any type of throttle/brake levers will work on any type of controller? I didn't see any clear recommendation, I see that all throttles have 3 wires and all brake levers have 2 wires. Is this more or less universal? My logic says yes - these are passive components but I am not so sure.
4. Controllers - is there a database or a way to recognize their types/particularities? I scroll around ebay/aliexpress and there are so many of them that it just blows my mind. Some have quite nifty features - but how should I use them? For example the one below, how should I start it? A normal button with memory or one that just shunts for a moment the circuit? And the self -learning, is this based on controller measurements made during the rides or it's something already programmed and the controller just applies the logic?
