Hi all, new around these parts and I am looking for some advice.
Been reading and reading and watching (thanks Tin Your Tip! You're a legend Dibley) and I am working towards making my first box mod.
Went to the Christmas market in town today and found this for £5:

It's large for a mod but this project I envision as home use mod and a chance to experiment in something that I am totally new to. Having a lot of room to work with will surely give me an easier time than the Extra Mints tin I have kicking about...
Thinking about using a 2x18650 battery box (in series) with an LM2596 step down. I also have in my shopping cart a switch, a 510 connector and an LED voltmeter. I believe I can also add a heat sink to the LM2596 which might be a good idea.
Am I right in thinking that this is all I need to make a VV mod with long battery life?
I will have an amp limit of 3A. If I set it to 4.0 V and run 1.4-1.6 ohm coils I will be able to happily vape in my preferred wattage range within the limits. Correct?
Using the LM2596 and the voltmeter, do I have the ability to both display the voltage in use and also the voltage remaining in the batteries? If not using the components from stealthvape, what would I also need to add to achieve this?
Sorry for all the questions and thanks for any help in advance.
