Ohm's law states that the current through a conductor between two points is directly proportional to the potential difference across the two points. Introducing the constant of proportionality, the resistance,[1] one arrives at the usual mathematical equation that describes this relationship:[2] v=Ixr
I = \frac{V}{R},
where I is the current through the conductor in units of amperes, V is the potential difference measured across the conductor in units of volts, and R is the resistance of the conductor in units of ohms. More specifically, Ohm's law states that the R in this relation is constant, independent of the current. You would want to use the ohms law formula, know your batteries limitations and if you use the formula this will answer your question

You first need to know your battery's amp limit (continuous discharge rate). The LG18650HE2 has a 20 amp continuous discharge rate limit according to the manufacturer.
Use the Ohm's Law Calculator to determine if the coil resistance of your RBA will pull more amps than the battery has to provide. Going over the amp limit of the battery can have catastrophic results. It's generally recommended to not use more than 80% of your battery's power for safe head room. Use 4.2 volts (fully charged battery voltage) as the voltage in the calculator.
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

The OP's battery is not in your list, so it doesn't say what her battery's amp limit is, so the list is moot to her.
Just remember that with a rebuildable there can be conditions during build where something touches the deck and causes a short. You might want one of the atomizer ohm testers to use before firing it up on a mech with no protection. Even if you incorporate a fuse in the mod, there's no sense in blowing it and having to spend several dollars for a new fuse.
This happens sometimes with all of use who recoil. Just the other day I installed my new 1.4 ohm coil on the Kayfun and fired it up on the Provari. I got an E1 code (low resistance) followed by an E4 code (overcurrent). All that happened was that two coils touched after dry burning and installing the cotton wicking. After I juiced up the wick I tested it. That's when you will see the overcurrent condition. Sliding the wick in can move coils together. Granted, your battery could take that hit without failing, but why leave it with a coil short when that individual coil could be heating juice? If that coil had touched the positive connection it would be a dead short.

thats the same battery as efest use in their 2500mah purple battery , those LG H2 have 22A continuous , so its safe to sub ohm around 0.3/0.4ohm
best regards
