Don't trust anything not coming from a reputable dealer. Good brand name batteries from reputable dealers are inexpensive. Fogstar not familiar with it but it has to be a rewrap of some battery. If you are talking about what the mod says on AMPS....that is what the chip provides not the draw on the battery

More info needed but if you're on a mech I'm starting with NO.
What's your mod? Mech or Regulated? How many batteries, and are they configured in series or parallel?
General rule is to stay at or above 0.2 ohms on a single 18650 mechanical mod, and that's assuming a true 30A cell.
Links are incoming.

I'd read up thoroughly on battery safety and figure out what you actually have, first. I'm not familiar with that brand, where did they come from? A vape shop, friend, or did you purchase directly? Vape shops are known to sell rewrapped batteries, so it's difficult to trust that these are really going to be safe. You have a lot of good reading material, above.
Best of luck,

Fogstar? I wouldn't be suggesting that on a short list. Stick with the Samsung, Sony, LG crowd from reputable dealers (no eBay or even amazon). Here's a chart of Mooch's recommended batteries with dealers at the bottom.
@DannyMc Rewraps like Frogstar should not be used as the actual performance and amp rating is unknown.
I'm guessing that you are using a regulated mod and the amp value you are talking about is from the display. If this is the case then you can ignore this value as it has nothing to do with what is being drawn from the battery. What determines the amp draw on a regulated mod is the wattage and some simple maths. If you can tell us what wattage you are using, then we can suggest a good battery to use other than the Frogstar.

Fogstar Batteries: "The UK's #1 trusted source of 18650 Batteries" They also sell Sony, LG, Panasonic, Samsung & re-wraps under their own brand. Seems legit, interesting... 
Well that certainly looks great! Still, depending on what he's running, 30 amps on a verified 20 amp cell is... problematic.
Regulated using the wismec reauleaux rx200s 3 batteries, i stay away from mech mods naughty them. In a series as far as i am aware and ive change my coils and there reading at .18ohm 120 watt and its cumin in at 25A
Oh. Amp draw is calculated differently on a regulated rather than mech mod. W/V plus 10% for efficiency of the board =A. As you're using 3 20A batteries in series a 30A load isn't an issue. What does matter is how many watts you're using, and of course whether or not the build is within the spec of the board. A quick and dirty figure is a 20A battery is good for about 60W, so add up the total and that's within the mod's range relying on the amp draw. That's 180W with 3 batteries. That amp reading you're seeing on the screen is board to tank not actual battery draw to the board.

Received these batteries for review PRODNA: Make Pro Batteries. Their website shows on the bottom the many uses for them except vaping. Since I do not test batteries with testing instruments only by using them in mods just wondering if anyone like Mooch has tested these yet?
Never heard of them, they sound like efest. They buy 2nd bin batteries, throw their name on it and make ridiculous claims to get people to buy their product. The only brands to buy are LG, Samsung and Sony. I used to recommend Aspire but I had two cells just randomly die for no reason.
They are rewraps with wildly exaggerated amp claims, there are no legitimate cells with anywhere near those mah & amp numbers, none, zip, zilch, zero, nada.
3.1aH 18650 battery @ 50 amps - is this some type of magic ?
A big no on those amp ratings - currently not possible with any chemistry in use.

I have only seen one vaper on You Tube have them which he only did only a un-boxing. I am using the 3100 mah 50 amp in a regulated mod to see how long they last, and how low I can go with coil ohms. Would not trust using in a mec mod.
If it's regulated ohms do not matter, watts do. If the battery starts getting warm stop using them.
Resistance doesn't factor into determining battery amp draw when using a regulated.
There is no possibility any 3000mah cell can have an actual CDR of more than 20a, and that would be first bin cells, not something re wrappers are likely to use.
There is no possibility the 3500mah have more than a 10a CDR.
If you don't have proper testing equipment & experience using it I wouldn't use those cells at all.
If for some unknown reason I just had to use them I'd treat them all as 10A CDR cells, I certainly would not exceed 30w per cell.
What is the point of using re wrap's with obviously erroneous amp claims when you can get authentic name brand cells usually cheaper.
