Please look over my plans for my first mod

[vshadowheart]

I am looking at putting together my first mod box, and I was hoping someone would look over the two main pieces before I pulled the trigger and ordered them.


DC DC Blue High Efficiency Variable Power Supply Kit with Voltage Display 2A Out | eBay


and


Plastic Battery Storage Case Box for 18650 Black EE4065 | eBay


With a horn switch between the voltage out on the battery box and the "voltage in" on the board. The voltage out of the board will feed straight into a 510 atomizer. I haven't messed with electronics in 15 years so I thought I would ask for help.

You'll need 2 batteries in series to meet the minimum input voltage of that regulator (4.5v), the battery holder should work for that. I'm a bit suspicious of the description that they put on that, so hopefully the picture is correct.

It looks like it's based upon a simple 'buck' DC-DC converter chip. It would be best to know what chip and pot value is used, as I don't see any way to be able to know what output voltage range you will get, otherwise.

It will likely output a max of something less than 7.4 volts with two 18650s in series powering it. Maybe someone familiar with that board will be able to provide more insight.
