Hey Gummy,
What do you mean, 38 post?
I don't understand that, wath diagram?

Not for a 3.7V box. The problem with the irfz48v is that it requires at least 4 volts to guarentee a saturated MOSFET gate. Even if your running 2 batteries, if one of them fails, it will fry the mosfet. There's a reason why he posted this and stated a specific part #. Yes others should work do to specs, but this one does work. The problem is these things like to be on, or off. Anything else and it turns the MOSFET into a resistor, and POP.
The IRL3103 has a RDS on from only 12mOhm = 0,012Ohm.
The maximum Voltage lost when your atty need 2A is only 0,024V.
When you say, that only 2,7Volt are on the atty, then you have problems with contacts or battery.
I belive, that your AAA Batteries cannot power 2A. I' shure!
Make the same voltage test by shortcircuit the FET between Drain and Source or hold the battery direct to the atty
Mojo,
I was concerned about this also after seeing the same video. Testing showed that there is no appreciable drop in voltage using the part raidy specifys. Try it by measuring your battery then fire the switch and measure the output. They will be very close.
