Hello everyone, I am new to the forum and this is my first post.
I am planning to make a basic mosfet to switch my aeg ( automatic electric gun ) for airsoft. Currently I am using 7.4V li-po battery and with time I will switch to 11.1V li-po battery and I expect around 60-70A peaks and maybe 30-40A constant current draw.
I bought 10 50n06 n channel smd mosfets and I am planning to use 3 in parallel on a pcb to make the design bulletproof.
Since I am not much of an expert on this field, I can you help me with choosing the right gate resistor and gate to source resistor?

 

Post your current schematic.

Regards, Dana.

 

With such a simple system, there is not a whole lot to worry about. If you had to worry about dead time, then the gate resistor would be crucial. But if it is a single low side switch (even when there are three in parallel), any 5 to 30 ohm resistor per gate should do the trick nicely. The pull down resistor is even simpler in nature. 10K is what I would start with. Good luck!
