Hi, I recently got me a Crystalyte H4080 motor. I run this on a Crystalyte 72 volt 45 A sensor/sensor-less controller (I run it in sensor-less mode and works well). But the case is that I now have two such identical regulators, after I removed two blown MOSFETS (an identical regulator from my previous ebike) and soldered back two new MOSFETs of the same type. The question is perhaps hard to answer, cause I have not found anything on the web or youtube about this scenario.
But here's the question: Is it possible to connect these two identical regulators in parallell to one hub motor ?, to double the current from max 45 A to max 90 A ? They will of course self-synchronize (in sensor-less mode)....... But if it is possible; should I run both controllers in a sensor-less mode, or in sensor-mode ? I can't see any trouble about anything "backfiring" from one controller into the other because they are connected in parallell and the current (let's say at 60A will divide in a Y-connection).
I must emphasize that I'm NOT going to use two hubs, only ONE motor. And ONE speed regulator, because the voltage from the regulator will be the same into each controller through a Y-splitter into both controllers, but the CURRENT out/in to the controllers will get "splitted" on the output side.
So if you can imagine a circuit as a water pipe mesh; the voltage is the pressure in the "pipe-mesh" and the current is the "water-flow". I know mediokre electronics and can't see any dangers, but perhaps there is someone with deeper insight that will see a problem. I've also thought about using diodes, but then the controllers won't get feedback from the hub to synchronize...
Thanks,

Clyte H4080, 72v nominal 20Ah, 45A (hopefully 65A with two parallell controllers (shared output = 32,5 A per controller and very little heat) if this works, and will make it possible to connect an extra battery in parallell later).
