I've been wanting to purchase (or build) A pv mod that is a self contained device that uses a rechargeable battery which EXCEEDS the 1000mAH barrier.

I was going to buy one of the new Vapre51 units, but I felt that the 360mAH battery would still be a somewhat limiting factor with regard to run time on a single charged cell. The build quality and design of the Vapre51 looks very nice, but I just felt that 360mAH was still not a large enough current storage capacity to justify spending $100 on another PV. After all, I do already have 3 DSE601's and many VX2 attys which I use with various other mods; mostly using a 2800mAH pack of 4 AA NiMH cells or an 1800mAH pack of 4 AAA NiMHcells (4.8VDC). I was determined to have a pv that would utilize a 3.7V battery with a current storage rating that (at least) broke the 1,000mAH barrier.

I have a handful of the ULTRAFIRE 18350 batteries that I use in my DES601 epipes (3.7 Volts @ 1200mAH), which are very similar to the the original DSE601 Epipe batteries (3.7 Volts @ 900mAH). I thought it would be just great if I could somehow build a mod that would encompass the raw power of these larger, longer lasting cells. I looked around and found that I had an old aluminum desoldering pump. This unit had a spring loaded plunger mechanism inside and I found that the 18350 battery will fit inside the aluminum cylinder after removing the orange plastic covering on the battery. I also did some light sanding inside the cylinder for a bit more clearance. I drilled 2 angled holes within the threaded tip of the desoldering pump and then mounted and soldered a small tact switch to the tip. I use the steel spring behind the battery and this thing works GREAT! The desoldering pump cost me all of $11.95

I went a bit too crazy with epoxy on the tip and around the switch, but this aluminum unit works very nicely. Note that ALL ELECTRONICS are contained WITHIN THE TIP, so this unit will NEVER have a broken wire, lead or contact within the battery cylinder . This unit has no LED and no fancy coloring......but it does have a 1200mAH battery instead of a 360mAH battery. When you compare the battery cylinder to my left thumb in the photo, you can see that this unit is definitely not huge, but a comfortably "medium" sized PV.

NOTE TO SHAWN: Your next mod could be the VapreMax 51.......having a battery with a rating that exceeds 1,000maH. This will provide MANY HOURS of vaping on a single charged cell. When folks hear how many hours it will run on a single charged cell, they will be scrambling to buy such a unit.
