You can use any ohms you wish, but your batteries have to be powerful enough to fire the coils safely. The battery spec that will tell you this would be the
amp rating, or
continuous discharge rate.
Those Panasonic NCR18650B 3400mah batteries you bought are
only 6.8 amps continuous, so you can only use a resistance
above 0.7 ohms. They are not a high drain battery, which is what you should be using if you are going to be using a RBA (rebuildable atomizer). Your batteries were designed to be used in flashlights, not mods.
1.0 ohm = 4.2 amp draw
0.9 ohm = 4.6 amp draw
0.8 ohm = 5.2 amp draw
0.7 ohms = 6 amp draw
0.6 ohms = 7 amp draw
0.5 ohms = 8.4 amp draw
0.4 ohms = 10.5 amp draw
0.3 ohms = 14.0 amp draw
0.2 ohms = 21.0 amp draw
0.1 ohms = 42.0 amp draw
0.0 ohm = dead short --> battery failure and thermal runaway
Notice the table above and how the lower in resistance you go the higher the amp draw from the battery. Pull more amps than the battery has and it will likely vent and go into thermal runaway. Not a good thing to happen in a metal tube mod.
Always know the amp limit of your batteries. Never push your batteries harder than they are rated for. If you plan to use sub-ohm coil builds, you'll need a 30 amp continuous discharge rate battery like the Sony VTC series.

The Safe Vaping Power Chart that you have been using is a general guideline for factory-made coils found in cartomizers and clearomizers. You can throw all of that away once you begin building your own coils with rebuildable atomizers.
