Hello and welcome to the forum
@kaloy69. Glad to have you here!
The SMPL is a "hybrid top cap" mech
mod. There are some special considerations you must be aware of when choosing what to use on it and how to make the adjustments so that you don't vent your battery.
Hybrid Top Caps & Battery Failure
I highly recommend you spend some time with
@Baditude &
@Mooch (two of our resident battery/safety experts) and visit their 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.
Here are links to some of Mooch's blogs:
Hand several links to
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:

OHM'S LAW
Ohm's Law Explained for Vapers
* My attempt at explaining Ohm's Law in layman terms and how it relates to

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.
