Redbrick 200a adding a 4th mosfet sandwich

[Corypi]

Hi haven’t flashed yet just have a quick question.
i burnt some of the fets on my redbrick 200a board and I have a second one today that I was testing the fets on and I have enough of the fry boards to make a 4stack high(so another 70a?)
Does the simonk firmware utilize any overcurrent protection or can stacking 4 high actually increase my esc capacity?
Also where is the best forum to discuss the flashing procedure? I don’t want to mess up my esc
