BMSBATTERY Q128C upped 500W rating to 800W?
I sent them an email requesting clarification.
Q128C #1....power rated for 800 Watts

Q128C #2....power rated much less at 500 Watts

PS: I have been overvolting my q128C (rated for 500W when I purchased in 2019) pushing it to 800Watts......but I had to reglue magnets twice now over a 3000 mile period. :-(

I glued my magnets with JB weld. high temp. What did you use ?
It should handle 800 watts but it is BMS battery.

First motor I used Loctite 9460 Hysol Aero Rated (High heat, tensil strength epoxy).
The second motor I tried JB Weld. I noted when I used JB weld that magnets made it hard to work because JB weld has Iron in it, so mix flowed away from center of magnet towards ends.
 
I got a confirmation from BMSBATTERY confirming that there is an 800W motor option now. Unfortunately it is only available in 201 RPM version. The 328 RPM version of the motor is not manufactured with 800W rating.
