Keeping mind those are
UN-PROTECTED ICR Li-Ion batteries, I HIGHLY RECOMMEND using a
Vape Safe Mod Fuse in this mod. This would at least give you the level of protection of a protected Li-Ion battery. These attach to the negative end of the battery via a magnet on the disk.

ICR Li-Ion batteries are volatile chemistry (as in flamable) should they short circuit and go into thermal runaway. When this chemistry of battery fails, it can be with fire and flames. Does this mod have vent holes for venting? With no vent holes a venting battery literally becomes a pipe bomb in a mechanical mod. I strongly suggest to keep any atomizer coil resistance at 2.0 ohms and no lower since you have no idea what the amp limit is on these batteries.
Just want your wife to be as safe as possible. I had a protected 14500 battery vent violently in a mechanical mod several months ago and it left a lasting impression on me.
