Wow, loaded question on this post.

It is a nice setup, and it can be very safe if you use it correctly. You have a nice battery and a nice mech.

It is all going to depend on how you use the setup. You can build this in an unsafe manor if you do it wrong, and, you can short and it can be unsafe.

I think before I could tell you if it is safe, I would need to know how much experience you have with electricity (batteries, coils, ohms law, etc.) and if you have experience with and access to a DMM or Ohmmeter.

What you have can be a very nice setup, but you need to respect the raw power you have, and there is some basic knowledge you need in order to make certain it is safe.

I know a fair amount about electricity, including all the things you listed. However, I don't have access to an ohmmeter, voltmeter, or ammeter atm.

The first thing I would do, before you use this setup, is get a DMM then. It doesn't have to be an expensive one, just one that you can read resistance and voltage reliably with.

If you build a dead short to the battery, this is a dangerous setup. This is one of the drawbacks to a mechanical (I use them, and my favorite one is my Nemesis). With a dead short or a very low sub-ohm setup, you will draw too much current from the battery. This can cause it to heat up, go critical, and vent (creating a very unhappy situation). You also do not want to over discharge the battery. There is no safety circuitry in a mech, so you can completely discharge the battery and ruin it. I like to check my battery as it comes off the charger (4.20 volts, that battery can safely handle 4.25 volts on a charge), and I like to recharge at 3.5 volts (some like to go lower, but I think the general consensus is absolutely do not go below 3.2-3.3 volts).

When you are starting out with this setup, check the voltage output of the battery often. Eventually you will get a feel for when the battery has discharged to the point it needs to be recharged, but start out checking very often.

Also, read a bit about mechanicals if you have not already so you know if something is going wrong. Above all else, if something doesn't feel right, stop immediately and remove the battery.
