Parallel wiring?

The resistor is only to light a led and so you don't burn it. No led no resistor. Just connect a heavy duty switch to either the pos or the neg to the atty. Use protected batteries and at least a 3amp push button switch.

Simple - if you don't know what you're doing then don't do it.
You can purchase a DIY mod kit very cheaply that will contain the protection circuitry that is required to vape safely and still have a blast putting it together.
Vape On!

how i can do protection circuitry in my home made mod to protect my self from battery????
Done the DIY kits, time to move on, learn more, grasp and develop, the final frontier and all that.
I wired in parallel last night and viola! 6 volts.
I guess you need a regulator to bring it down, no biggy, I love 6 volts!
So much to learn!
EDITED to remove silly question.

At series or parallel batt`s connection don`t forget about protection. Or use protected batts, or make protection or buy protection PCB, or use protected and make extra protection 
. In parallel if you have one of batt 3.8V and one 3.7V for example, that 3.7V will charge from 3.8V.

To get 6 volts in parallel you must have two 6 volt batteries, What batteries are you using? If you have two 3.7 batteries in series and you have 6 volts, they are dangerously undercharged and you shouldn't be vaping them.
This might help the OP a little...
Parallel, batteries connected positive to positive and negative to negative...you don't get extra voltage this way, but you will get increased battery life as each battery is working half as hard to supply its voltage. In the case of vaping, you would get 3.7 volts this way, usually.
Batteries connected in series, positive to negative, you get double the voltage, but with no increase in battery life. Each battery is supplying it's full voltage at all times, which is why you get increased voltage.

My advice it`s : don`t use LiPoFe4 batts CR123A on mechanical mod .Very dangerouse batts, like he said @BJ43
umm how in the world are you getting 6v from 2 paralelled batts . Thats impossible. 2 3v Batterys in parallel is still 3v. 2 3v batterys in series is 6v.
Also like said above those small batterys are not the safest . I always hate hearing about them being used because they cant handle the load of a ecig expecially if running LR attys

Either LiFe batteries, half discharged or non-rechargeable lithium cells in series, of course if someone likes exactly 6V
P.S. Funny topic: guys trying here to get a knoledge about basics without elementary searching, but nobody tries to write a complete handbook for them. Who is lazier?
What TommyG said. Parallel wiring is positive to positive and negative to negative. Parallel wiring gives you the same voltage at output as the individual batteries deliver, but more capacity in amperage and longer battery life before charge. Parallel shoudl deliver 3.7v dc to the load (atomizer).
Series wiring of batteries is additive in voltage, but the amperage delivery capacity will be less. You should get 7.4v dc from two 3.7v batteries wired in series.
A single battery mod with a boost circuit is much safer than a dual battery mod. Dual battery mods can experience a situation involving reverse charging where the battery with the higher charge can deliver current rapidly to the battery with the lower charge. Since this happens quickly, one battery can overheat and explode. This is what happens to the mods you have heard about where someone gets it in the face while vaping. It's not a pretty sight, I'm sure.
Lithium batteries contain a thick electrolyte. When it heats and expands, it does so at a rate that causes venting. When the venting occurs at a rate higher than the mod or batteries can expel, the result is that the batteries swell and explode and the mod itself can direct hot, caustic, thick liquid lithium outwards along with an explosive force. If you are vaping when that happens, you can imagine the result.
Protected batteries are designed to cut the circuit to the mod if overtemp or overcurrent occurs, that can be too late or the protection circuit could fail to act. The failure mode of IMR batteries is high heat, but they are not likely to vent vigorously or explode as protected batteries can. I'm leaning toward and using IMR these days.
