With what I'm reading the amp limit is way to low. batteries is one thing to not bargain for personally.
Plus the general rule for us vaper's regarding batteries and chargers. Avoid using anything with the word fire in it. Sich as ultrafire and trustfire. This link is the only kind I could find that was similar

Edit: 4x Ultrafire 18650 3.7v 5800mah Rechargeable Li-ion Battery + 1x 18650 Charger - - Amazon.com
I found this, but even that looks sketchy
"Compatible with: Battery appliances such as emergency lighting, portable devices, power tools."

I never use any battery with fire in the brand name.
Take a look at the quality from these batteries. I would never use Ultrafire for any purpose.

You should not use that. And no other ultrafire battery for that matter either. Sorry to say.
For mechs you can't go wrong with sony vtc4/5s. Reliable and safer than most others.
If you search for the user baditude and look at his bloggs, he got a great blogg explaining all about the batteries.
(Man i gotta bookmark that so i can copy paste each time this question comes up
)Good thing you asked us!

Exactly haha about @Baditude
I have a couple up of his

Maybe he can chime in some more. With the formal post that he usually does
When looking for batteries for use in ANY mod you should be looking at the CDR (continuous discharge rating) first, NOT the mAh.
You are going to want a safe-chemistry, high-drain battery with a high CDR. How high? I try to never exceed 50% of the CDR (continuous discharge rating) of a fully charged battery (4.2v). So with a 20A battery, that would be 10A. This Ohm's Law Calculator tells me that a 0.4 ohm build is as low as I would want to use.
The reason that I place a 50% limit is because as a battery ages the mAh of the battery degrades, as the mAh degrades so does the batteries c rating (amp limit). So down the road, a 20A battery may only be a 10A battery."
With a 30A battery (like the Sony VTC4) I would only build as low as 0.28Ω.

Since you appear to be new to mech mods and/or rebuildables I highly recommend you spend some time with @Baditude (one of our resident battery/safety experts) and visit his blogs. You are now 100% in control of your own safety (and others around you). Make sure you purchase an ohm reader and a voltmeter or DMM so you can measure your builds, check for shorts and measure the remaining charge on your batteries.
Baditude's Blog - Table of Contents: The blogs that address battery safety, Ohm's Law, CDR (continuous discharge rating/Amps) and how they all work together are detailed below:
BATTERIES
Battery Basics for Mods: IMR or Protected ICR?
* Another essential read to understand which batteries are safe to use in mechanical and regulated mods. Includes a frequently updated list of recommended safe-chemistry, high-drain batteries with their specifications.
Purple Efest Batteries not as Advertised
* A cautionary blog that reveals that the purple Efest batteries may not have the specifications advertised. Also includes a commentary on "continuous discharge ratings" vs "pulse discharge ratings" of battery specs.
OHM'S LAW
Ohm's Law for Dummies (Vapers)
* My attempt at explaining Ohm's Law in layman terms and how it relates to vaping.
Explain it to the Dumb Noob: Ohm's Law Calculations
* As simple as it is to use, some people have a tough time grasping the concept. Warning: Includes graphic photos of mod explosions.
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.
* RTD Vapor
* Illumination Supply
* Lighthound
* Orbtronics

Guaranteed face-burster in a mech with a sub-ohm build. Batteries are like a see-saw with capacity on one side, amp rating on the other. If it is a 5800mAh battery, which I doubt, then the amp rating must be minuscule. Probably 2 or 3 amps at most. Ditch it and get a some Sony VTC4s or Samsung 25Rs.https://www.e-cigarette-forum.com/forum/members/dbrandt01.209062/
Susan-S has just as much information too haha. I so need to get that copy and pasted into a word document.
