Is a .3v Drop off Acceptable for a Mosfet Box Mod?

[MonkeyTokes]

I just built a couple mosfet boxes for co-workers and friends, I've been testing them the last couple days to make sure nothings going to fail before I pass them off. I'm reading .3v and .7v less than the battery voltafe while not underload;
I put a voltmeter led display on them and it reads .3v less on the neg and positive of the connector while underload and my multimeter reads .7v less on the positive and negative post of the atomizer with a .2ohm coil. Is this acceptable or am I losing too much voltage somewhere? I used 14 and 16g solid coper core wire with a 3034 MOSFET and 15k .25w resistor. They still work far better than any mech mod I have but I just want to make sure they are at their full potential. Thanks for the advice

Its normal but if you want to drop down to ~.02v range read this post.

I have a volt meter in the door of my dual parallel box that has a adjustment that I zero'd it against my hand held meter and battery voltage right now is 4.10. With a .34ohm load against it, it is reading 3.92 for a 0.18 voltage drop.

Im ok with that, its about where yours is I think.
