There are only a few battery manufacturers in the world who make their own "cells", including LG, Samsung, Sony, Panasonic & Sanyo.
All the other brands on the market buy the second and third tier cells from those manufacturers and re-wrap them under their own brand. These are "second and/or third tier cells" which did not meet the higher standards of the original manufacturer. In order to compete with the original manufacturers' batteries (first tier), these other companies feel obligated to publish specifications which are inflated to make them appear superior to those of the original manufacturer.
Do your research before you buy. Decide what battery to buy depending upon the application that you will use them. @Mooch has done independent testing of many of the batteries available to use. Look for the results for the top batteries you are interested in, in his => blog.
BATTERIES - WHERE TO BUY
Only buy batteries from a reputable supplier (not ebay or Amazon) as there are many counterfeit batteries being sold. Here are several reputable battery suppliers in the US.

What Susan means about application is:
There is a relationship between mAh (capacity) and CDR (continuous discharge rate) that acts like a sea-saw. The higher the amount of amps (CDR) that a cell can provide, the lower the overall run time of the cell will be. That's just how the chemistry works, so it's about choosing a cell that fits your application.
Eg.
If your setup requires 18 amps, then a 20 amp CDR cell like the LG HG2 is a good choice, as it can safely provide this number of amps with some headroom and has a nice 3000mAh capacity.
If your setup requires 28 amps then the LG HB4 would be a good choice as it can safely provide up to 30 amps. However it has a 1500 mAh capacity, so you will get less run-time.
more details:
CDR - continuous discharge rate
This is the number of amps that a battery can safely supply continuously. For example if your device gets stuck on unattended, it will completely discharge without issue. Some cells have grossly inflated specs printed on the side, which is why we lucky monkeys on ECF stick to the values provided by the testing that Mooch has done.
mAh - capacity/run-time
This is how many amps the cell can supply against time.
3000 mAh = 3 amps for 1 hour, 6 amps for 30 minutes, 30 amps for 6 minutes etc.

I would definitely recommend Sony VTC 5A. It has 2600 mAh capacity and delivers 25A. Mooch's test confirms that it is a very good cell.
I thought I read mooch's test confirming the VTC 5 as a 20A CDR cell with a 2600mah capacity.
To the OP, if you don't go above 60W per battery then the LG HG2 or Samsung 30Q due to its 3000mah capacity.
I don´t know why, but somehow with VTC4, VTC5 and even VTC5A I have a Feeling, that my eVic Mini even at 15W is getting really really warm. According to the specifications the VTC5A can even reach on the Surface of the battery 80 degrees...for me too much
I only reaches that temperature when operated continuously at its rating. It's about the same as any other battery when they're operated at their rating.
When pulsed, as is done when vaping, it runs much cooler.
