I made my first mod today. I used a battery box for 2 AAA batteries. The mod consists of a single IMR10440 battery, on/off switch and a momentary switch for vaping. The mod works but the box cracked a little near the atomizer connector. I also had to remove some plastic from the top where the momentary contact switch is located. It isn't the prettiest mod but it works, and it is my first mod. Here are some pictures.
