I am shunt modding a controller, and the mosfets are SDA0Z 40DY. I googled forever found nothing. The controller pulls 24 amps peak and can handle up to 84V. It has 100V main caps in it. I did shut mod it to do 43 amps so far, but I'm not sure how many they can handle, so I am wondering if any of you guys know or have a close idea, thanks! I don't really want to buy 4110 mosfest and swap them out... I'm not sure what I will do about beefing up the traces, it seems to have some 14 AWG sized 0.10"x .025" copper rails connecting the phases on the top side of the board. I may have to run wires under the board. OR maybe they can handle 45 amps....
Can you Identify these mosfets?

If you can't find anything on the web it might be a fly by night company making both the controller and the fets.
Heat is more your limit than anything. that should be your guide on how you should shunt mod.
Too hot to touch for more than 5 secs outside = way too hot inside, that's my rule.
For the shunt mod, just add a 2x thicker net amount of solder to the existing power bus on the bottom of the right pic, it should help. Thicker phase wires to account for the modifications you've done is a good idea too. And probably battery wires as well, if the stock ones are thin.
