Upgrade Flipsky 75100?

It's rated for 120A peak phase and the software only outputs 110A no matter what I type in the current section.
I would like to upgrade the mosfets and use a higher current and would like to know if there is an option to bypass that software limit.

You would have to recompile the firmware below with increased current limits

How to update firmware on the Flipsky 75100 FOC ESC

Ahh thanks alot!
Any recommendation for the best mosfets out there that fit the 75100?

Managed to kill my 75100 in 3 min while testing over temp protection - fused gates of 2x FET's,

From what I checked, there are no real upgrades worthwhile in the TO220 package.
What I was thinking about is to double up the amount of FET's.
Basically making a 12FET design. This would "theoretically" increase limit to 200A.

I do think its not that simple, probably traces will start melting?

Do we also need to add any extra gate resistors etc?

This is the stock FET - mdp10n027

Meanwhile I'm running it pretty hard on my scoot with a 72V battery.
Running 180A phase current bursts :lol:
It's all about the cooling.
