Is this Safe?

That is a very low build but as you are using a regulated mod, the mod should refuse to fire if it is too low for it. Too low for me though

 

If it is on a regulated it is safe. Sub ohming that low only really would make sense on a mechanical though. Low resistance is the only way to increase power on non regulated devices. On a rsgulated device you can turn up the power and use coils that are larger. Coils that would not even fire on a mechmod work just fine on a regulated. Try some bigger coils I think you will be pleased.
These are .42.

 

Regulated mods are pretty safe to experiment on.

 

As long as the resistance is within the minimum spec of the mod you are fine. A regulated mod will deliver the selected watts, coil resistance does not factor into it. However big low resistance coils will need a lot of power to light up, and will have long ramp up/down times.
Imren and Holm life are rewraps with exagerated specs, I wouldn't use them. The LGs are good 20 amp batteries good for 60 watts each. So you are safe with either mod at 100 watts, though the Triade will give you more runtime as it has three batteries.

Yes, I'd say its safe, but you will probably not get the best battery life. The mod should shut down if it's problematic, but you will be running your setup pretty hard at that wattage, even with higher Amp cells. It should be safe to do it, in the sense that hopefully the mod will just refuse to fire if anything does go wrong. I would agree with the three battery mod suggestion, that or running a higher resistance, and stressing your mod and batteries less.

Best of luck,
