Battery:
Panasonic NCR18650PF 2900mAh - best general purpose battery (hybrid) with low internal resistance, high-drain and safe-chemistry, high battery mAh capacity, and 10 amps.
If planning to do sub-ohm with a Rebuildable Atomizer, then the Sony US18650VTC4 2100mAh 30 amp is best.
Chargers:
Pila - tried and true; considered to be the best charger for the last few years.
Xtar VP-1 - a recent challenger to the Pila as the best charger. Has a nice LCD display.
Battery Basics for Mods: IMR or Protected?

Why settle with 2900mah when you can go with full 3400mAh also from Panasonic.
Sigelei 20W is pretty safe to use with Pannies 3400mah.
This battery is a viable option if you only plan on using factory built coils (clearomizers or cartomizers).
However, do not use these with a Kick or a rebuildable atomizer. You should use an high drain battery for those. The 3400mAh Panny is not a high drain battery.
I'm using an eFest 18650 EMR, Depending on where you get it from they're around the 2,000mah mark.
Mine's a 2,000 but i found one here from a US Retailer that's 2,150. Only downside though is that it's black... mine's BRIGHT RED

0.5 ohms will pull 8.4 amps from a battery. Do the math. Always use 4.2 volts (fully charged battery). Voltage = 4.2 volts. Resistance = 0.5 ohm. Current drawn (amps) = 8.4 amps. Ohm's Law Calculator
As I pointed out earlier, it depends upon what you place on top of the mechanical mod. In a "low drain" application like factory-built coils with normal ohm resistances, the Panasonic-B 3400 battery is fine.
When you introduce a "high-drain" application such as an RBA or a Kick (or use them in a regulated mod), these batteries fall short. Their amps are barely acceptable for some high drain applications; but their high inner resistance and hybrid chemistry weighted heavily to Li-ion ICRs make them a low drain battery, not a high drain battery. A technical explanation is provided in the following link:

My thoughts on batteries is that having a high amp rated battery is always better than having low amps, regardless of the mah ratting. Then if you do decide to go lower you don't have to buy more batteries. Also, the voltage drop is less on a high amp than a low amp, least this is what I have found on builds of 1 ohm and lower, so one has a longer useable voltage with a 30 amp 2100 mah battery. A 6.8 amp continuous rating is in the 18350 class, Max pulse amp of 12 amps for 5-6 seconds, does not sound promising to me. Personally would not use this battery in any of my mods, but that's me.
I have the Sony VTC4's and find them quite excellent. Was able to snag up 3 Efest Purple's 35 amp 2500mah 18650's to see how the stack up against the VTC4
I have both the Xstar VP1 and the Efest LUC 4 bay charger. Both have nice voltage meters and multiple amp charge selection, though the Xstar goes down to .25 amp and the Efest only down to .5. Feel the Xstar is superior, never overcharges and has some nice features. The Efest is nice, but notice it does charge batteries up to 4.25 volts, and the Xstar doesn't.
I had to get the Efest charger to accommodate my 26650 and 26500 batteries. It also come with an usb port to charge other devices too. So I can use it to charge the SuperMax, cell phones, and mp3 player also.

OK so say ill be building coils between 1-2ohms & be using a sigelei 20W, what specific battery would you recommend?
Bottom line, you want it to be a high-drain safe-chemistry battery; either an IMR or hybrid.
Next, if you have no intentions of ever doing sub-ohm coil rebuilds, you don't need a 20 - 30 amp battery, any 10 amp one will do. At this point, higher mAhs start to become more attractive.

So it between the Panasonic 18650B 34400mah & the Panasonic 18650PF 3900mah?
I wish i knew more about batteries, not in a complete technical standpoint. All i really know is that mah = battery life and 18650 is the size of said battery.

Your "mAh" numbers are off, likely typos. The Panasonic 18650PF is 2900 mAh and is a high drain hybrid battery.
The Panasonic 18650B is 3400 mAh and is a low drain hybrid battery.
Which one would be best for you? It depends entirely upon what you plan to put on your battery device. The 3400 mAh "B" battery would be best utilized if you are going to be using factory-built coils (clearomizers & cartomizers) for long battery use.
If you ever plan to use a Kick module in your device to regulate your battery voltage, you'll need a high-drain battery, so the 2900 mAh "PF" would be the better choice. Same holds true if you plan to put an RBA or RDA on your device. This battery is high drain and has higher amps than the "B", which the Kick and RBA requires.

I plan on making coils around 1-2ohms, so I guess the PF would be better in my case
Considering you can get the PF for the same price as the B on amazon or even ebay why not just buy the PF to be safe and have a more versatile battery. It can be safely used in other devices that the B just won't cut it.
Sigelei 20W amp limit is 5,35A, and @standby it takes 100mA(Provari @standby take 0,93mA). So higher mAhs IS attractive for Sigelei 20W
I don't understand your point. What does amp limits have to do with mAh? They are two different types of specs and have nothing to do with the other.
Those Panasonic NCR18650A 3100 mAh and NCR18650B 3400 mAh batteries are not high drain batteries. These batteries were designed for FLASHLIGHTS. High drain is the most important criteria for any regulated battery device. High drain batteries for regulated mods. Period.
Between the two, higher amp limit is more important than higher mAh for a high wattage regulated mod.

Cheers Baditude, your battery posts here and elsewhere have been invaluable to me. I've just ordered four Panasonic NCR18650PF (unprotected 2900mAh) 18650s to go in a Sigelei ZMax V3 telescope APV.
Number one concern for me was safety. The PFs are the new "hybrid" (Lithium Nickel Manganese Cobalt Oxide [LiNiMnCoO2]) chemistry and reading around suggests they are as safe* as IMR (Lithium Manganese Oxide [LiMn2O4]):
- Types of Lithium-ion Batteries
* as far as safe can be; that is to say, least likely to vent/burn/explode when used properly. I'm not into mechanical mods and the APV won't accept an atomiser resistance lower than 1.2 ohms but will cease operation when the battery discharges to around 3.3V. I'm charging with a NiteCore IntelliCharger i2.
