There are 2 basic 5 volt mods , resistance based and regulator based ( there are some that are different but very few )
A resistance based 5 volts uses a resistor to drop some of the voltage from the batteries , the voltage applied to the atomizer will drop with the battery voltage.
A regulator based mod will maintain that voltage until the batteries die or drop below a certain point ( batteries being mostly drained ) so the vape will be more consistent over the life of the charge .

'Sweet spot' is wattage not voltage and that's around 6.5 to 8.5W. With a 5 volt device that means an atty with an ohm rating of @3 to 3.8. With a true 3.7V device (eg. 14500 batt) that means an atty with an ohm rating of around 1.6 to 2.1.
I have a 5volt Bartleby (box mod) and sold my protege PT that gives 5V because my 2.1 ohm 510 attys (of which I have a cache ;-) work just fine on true 3.7v devices. I usually have a 3+ ohm cartoz or the 901 atty on the 5V Bart.
Mr. Green the sweet spot is a moving target so to speak , the variation in atomizer resistance is all over the place ( even from batch to batch in some cases )
5 volts gets you in the ballpark for most atomizers , however changing the voltage to match the atomizer addresses this issue.

I don't really worry anymore because with the Buzz I can adjust it to any atty or carto out there. I have many mods and passthroughs all 5volt collecting dust since I started using this mod. It's at notcig, take a look.
But you still have to have an idea of what ohms your attys and cartos are running. I like the idea though. Is that the one from Nuck?
Most atomizers you have an idea of what the ohms are , I think there is a chart in the modder;s section ? or use a DMM to test them
No not Nuck
BuzzKill:Most atomizers you have an idea of what the ohms are
Yeah, hopefully someone that knows the value of a variable voltage device would know. My point was that 5card said he didn't have to 'worry about it' but you still have to know what ohms you're putting into the equation or you're going to either burn out an atty or not get much vapor

No not Nuck
Oh, ok Buzz, Thanks. Assuming this is your mod - name and all ;-) Good idea!

As other have said - it's about wattage not volts.
personally i use 510 LR attys on my indulgence, 510 standard attys on my 5v passthrough and 801 attys on my 6 volt device.
Keep in mind that most 5/6 volt devices are quite large - i generally only use mine at home and use the 3.7 w/LR atty whilst out and about due to the much smaller size.
If you don't already have a true 3.7 volt device i would give that a go first, it is quite a jump from standard batteries. They put out 4.2 volt on a fresh charge, you're not stacking lithium batteries (can be dangerous apparently) and the size is nice and small (relative to HV mods)
my only mod is my indulgence from eastmall, it's cheap, has multiple atty connectors and 3.7/5v passthrough/6 volt options.

I use many different cartos, KR8s, V4Ls, 510, plus sometimes I drip with either a 510, 901, 801 and have found the resistance chages in units even in the same package. With the buzz I can set it to a level that gives me the most for that unit. Do I check a chart each time? No, if it is to hot I turn it down. If it's to cold I turn it up. Pretty simple really.
So standard 510 batts are not true 3.7v? I take it you can't use LRattys on standard 510 batts then?
Standard 510 batteries are regulated down to about 3.2V. There is a slight but noticeable improvement with a true 3.7V device. The "sweet spot" is different for different people. Some prefer around 6W, others prefer it in the 10W range. You won't know your personal preference until you try some different setups. This chart will help.
Theres that chart , cool it has been updated since I last saw it , it now has LR and HV attys NICE WORK !
Mr. Green the regular batteries are low capacity and low discharge rate ( as far as we know ?? ) you really need a high capacity and high discharge rate battery for LR atomizers for the best performance and safety.
The reason I say safety is because over discharging a Li-ion battery to fast that is NOT designed for high discharge currents can cause the battery to fail , it will definitely reduce the usable life of the battery in any case .
Google to Battery University and read up on Li batteries.

Most vendors will have a blurb (likely from the manufacturer) that you shouldn't use LR attys with batts less than 440mAh (not sure if it's 440 but that's close). But there is no good reason for that other than the fact that batteries with less than 440mAh will need recharging more often using LR attys because of the power used. There is no danger in using LR attys with batteries with less mAh than that - the atty will go before the battery (however, a shorted atty can affect a battery on occasion). But it could affect any voltage or voltage regulated battery like the 510, mega, eGo as candre points out how those voltages are dumbed down a bit.
That said, I use LR attys on regular and mega batts and they work fine - you are just recharging at an earlier time that with regular 510 attys And the batteries life time will also be affected. The vapor, however is enhanced and you're likely not going to burn out an LR atty at 3.2V whereas you can with 3.7V (let me assure you ;-) It's a tradeoff I'm willing to take with the few megas that I didn't sell. Mainly though, I'm vaping regular 510 attys on Bartlebys, a Protege and a few Tornados.
I have one of Bigbuyer's 5V Mod Boxes and it's simply awesome and the price is cheap enough. The unit is small and fits in your hand very nicely. Plenty of vapor and throat hit too.
Thanks. It was missing the 3.2V battery voltage as well, as when it was made, most people still thought that standard 510 batteries ran at 3.7V. The red and gray shaded cells are too high (>13W) and too low (<2.5W) respectively. If you're interested, the source spreadsheet is available in several formats here.
I totally agree with this - it is a subjective standard that varies from individual to individual but having burnt out 2 attys at 9+ Watts and a few cartoz at 8+W, part of my 'sweet spot' is to not have to pay attention while vaping ;-) I didn't when I smoked and don't want to have to now. That said, if you do pay attention and don't take too long of drags when you're vaping above 8W, you can eke out some more vapor but to me, it's not worth the trade off and you can lose some flavor as well.
My personal favorite is 901 attys at 5V (about 6.5-7W). I agree that burning out attys in less than a week is a PITA, but I know a few people that won't even consider anything less than ~10W on their setup. It's all about what you prefer.
If you need massive TH and vapor to enjoy vaping (as some people do), then you'll have to put up with the hassles that come along with high wattage. Attys are only about $7 a pop, and that's a small price to pay compared to smoking. The key thing is to try it at least once, otherwise you'll never know if HV vaping is for you.
As far as i know, the jury is still out on LR attys on a small battery, they are fine on tornado/ego though.
the standard 510 battery puts only 3.2 volt on the coil - it translates to a decent drop in wattage vs 3.7 volts
Right on all points - esp. on the try it at least once part - ie don't say it's no good unless you've tried it. And LOL on loosing them in less than a week - mine was 2 in one day, so close to each other it was a head slap ;-) Probably my lack of a need for a big throat hit is a big part of my sweet spot too. 901 at 5 volts is sweet.
