Good evening,
So Im having a little strange predicament. Now don't get me wrong I've been around, I'm not fully green when it comes to blowing up controllers, jimmy-ing open stubborn hub motors and of course globs. But this issue is interesting to me. So basically I ended up blowing up my previous controller (YKZ7280) of course seems the weakling mosfets they put on there aren't up to the challenge of a solid soldered shunt.
Well I ended up getting it's big brother the YKZ120150. I really like these controllers , cheap and very effective. During shipping I noticed all my hall sensors blew as well so I replaced them with Honeywell 41Fs and rewired the motor with 10 Gauge wire. (Got some trippy wire off Amazon, boasting 1060 strands of tinned copper and floppy as freshly cooked spaghetti). Anyway it turned out well and the motor passes the hall voltage spinny tests. Definitely not shorted anywhere.
So here the issue when I wired everything and here's the two working scenarios I get from trying different phase/hall combinations.
1. When bike is lifted and I'm not sitting on it motor spins like crazy going up to 120+km/h on the odometer on the phone program that controller uses. When I sit down and try to go the motor suddenly appears to have no torque and just makes sounds that I experienced when LVC has been hit or there's a poor contact somewhere. Kind of grinding/slipping/crunching noise Im sure you all know what I mean.
2. Bike runs smooth but never using more than 20 amps even at takeoff, kind of sluggish but the motor sounds glorious. However the battery consumption is insane draining my batteries within minutes. Also there is a huge voltage drop every time the the throttle is used. Basically some messed up false positive.
Im a bit confused on what the issue could be. Is it more than just my phase combinations? The motor is wired like this:
The stock controller was wired color matching and looks like this:
New controller as well as the blown one have wiring like so:

I don't even remember what I had beforehand when I blew the 7280, I did but after a day of hall/phase combinations and troubleshooting I can't even think straight.
Basically Im running Y-Y/ B-G/ G-B as my hall and the same for my phase. I went through a few diagrams that help with this but still nothing.
Any input would be appreciated.
Thanks.
