Dual mosfet in unregulated 18650 parallel box. HELP

Wattup vapefam. I'm getting into building unreg'd boxes to accomodate for my fancy builds, and in a parallel 18650 box, I want to run dual mosfets wired in parallel, but am unsure just how in the hell to accomplish that. I've read many things about possible unbalance, other people say there's no problem at all, I dunno. If there's someone who knows what they're doing please let me know what I can do, or throw up a diagram that makes sense.lol
Thanks,

You can just stack them, wire legs together from both mosfets, only need 1 resistor.

much appreciated, that's exactly what I needed. Though I do have more question. I've ordered 4, 15 amp fuses, in an attempt to wire those in parallel and make a 60 amp fuse, how would I go about wiring those? Or would it be possible to actually use a 60 amp fuse from a car more or less?

Little over kill 60 amp, the most commonly used is 2-15's like the diagram below. Most will use a resetable fuse that are a bit pricey, but auto fuse will work fine too.
