I'm not at all familiar with the GEB batteries, and could find no specifications in the C rating or the continuous discharge rate. I would not use those batteries in a mod until those stats can be confirmed.
The Samsung battery should also not be used.
My research says the Samsung ICR18650 2600mAh battery is a protected ICR battery. This means its chemistry is not "safe-chemistry" nor is it "high-drain". Regulated mods typically perform best with high drain batteries, as their buck boost processors need the high drain ability to do higher voltage production. ICR batteries typically have insufficient amperage to safely fire regulated mods at high voltages, RBAs or Kick modules, usually less than 5 amps. The Kick comes with instructions recommending its use with only IMR high drain batteries in mechanical mods.
Below is a list of recommended IMR or Hybrid batteries which I have collected for both mechanical and regulated mods. Pay attention to the identifying numbers and letters when choosing a battery.
Special IMR/IMR batteries are required for safe sub-ohm vaping: batteries with a continuous discharge rate (CDR) of 20 amps or more are required. These batteries insure only using 80% of their capacity and allow some safe headroom for added safety with sub-ohms.

When using sub-ohms, you need to know the amps in continuous discharge rating for your battery, measure the ohm rating of your coil, and then use the ohm's law calculator below to find the amp draw the coil will pull from the battery. Never exceed the amp draw of your battery.

If you can not understand the above information, you have no business doing sub-ohms.
