Okay, to further look at the potential of a 20s3p vs a 30s2p battery addition to a GT. I went looking for the weakest link in the setup.

The ideal would be a superflux motor, Thor 300 or x12 controller and enough room for this big dumb battery idea.

Looking at either controller. Neither would have trouble with the voltage below 100v and neither would have trouble seeing 300amps across the mosfets.

I've been having trouble finding the peak power of the superflux motor. They give a peak torque of 80nm.

I decided to use some information from another spec sheet I could find and try to cross reference the info to fill in some blanks.

The GT motor, hypercore, produces 26.6nm at roughly 980 rpms. This produces a total wattage output of 2726watts.

If we expect the NM of the superflux HT to be 80nm then at 980rpms it should produce 8210watts with the same voltage and enough current to draw from.

That would be 109amps at 75V. So far, I have seen higher then that on a lot of videos. So, either my rpm estimate for their peak power is off, or my math is just dumb.

Regardless, changing the amount of current available for the motor has its limits, but there is still room above 20s2p. If we work with my numbers.

A Samsung 50s 20s2p battery produces 50-90A of continuous to burst discharge. This leaves at least 19A on the table of current draw from the superflux. Granted we're getting into territory of overheating the motor with the stress, but it is room.

That means a Samsung 50s 20s3p battery, putting out 75-135A of discharge fully utilizes the superflux motor. And should still fall within the controller capabilities based on the typical motor current values I've seen adjusted for the 33% potential increase of current.

But we may just see a Thor overheat if I build this thing. I'll add a copper heatsink to the underside of the controller, flush with the bumper. This isn't a trick board, just downhill. so, obviously no nose slides.
