25A Ideal Diode (PN 5389) heat-sinking for higher current?

I noticed that the FET on this board is rated for 100A of continuous current. Is the 25A limit driven by trace width/thickness or lack of component heat-sinking?

I’d love to operate this board at 50A continuous and I can quite easily accommodate some kind of heat-sink or additional cooling. I’m just trying to understand if the board itself is the limiter.

Hello.

It is limited by heat dissipation; if you can get the heat out, you should be able to get 50A.
