I think this will stay at home for awhile. I understand ohms and I've got great authentic
batteries. I didn't think I'd get it ordered at that price.
You'll be fine as long as you are confident in your understanding of Ohm's. That and your coil building prowess.
Take some extra time with your coil. Put a dang flashlight up on it after you've got it installed.... no sneaky connections going on where you couldn't see and all that? Check the switch internally, no loose parts?
And PLEASE.... use an Ohm Checker. For VW/Temp mods these days you almost don't need to bother. Half of them have it built in.
But for Mechanical mods the three biggest rules I can think of:
1.) Know your continuous amperage draw
2.) Know your coil's Ohm
3.) Understand the relationship between these two things
(Know as in, no possible variation or misunderstanding, you KNOW what they are.)
With a Squonker/Box Mod you're already set. AFAIK those things require a lot less maintenance than something like a Nemesis-style tube mech. Man I was shining my contact pins/threads with Noalox for lowest possible amount of voltage drop, constantly checking that my mechs had good solid tension, tweak the switch assembly once or twice a day and make sure the tiny pin didn't fall out....
By comparison you've got it easy, just take it slow and master the basics!
