18650 Variable Volt mod w/ built in charger

[Silent Soldier]

My latest creation.

Features:
AW 2600mah 18650 battery
TI PTN04050C adjustable boost converter chip
3.6v - 5.1v adjustable range (approximate)
Built in 200Mah charger w/ LED indicator (red when charging / green when fully charged)
mini USB port
3a switch with 3a mosfet
digital potentiometer with 2 button up/down control

Comes with
5ft USB to mini USB cable
USB wall adapter

The charging circuitry is run to the battery so this mod can be used as a passthrough. The battery takes about 12hrs to recharge if completely drained, how long it takes to drain depends on the set voltage and usage. During testing I got about 4 days of moderate vaping at around 4.2v. The battery is held in place with battery clips and can be removed or replaced pretty easily just remove the cover with a Philips head screw driver and pull the battery out. All of the PCB's and vital components are covered with electrical tape and secured in place to prevent shorts. This mod has been vape tested and works very well, it will come fully charged and ready to vape. Due to the build cost this is currently the only one I have, however if there is enough interest I will consider making more.

Swapped out the expensive AW 2600mah battery with a generic 2200mah battery & dropped the price down to $70 shipping included. If you want to upgrade the battery at a later date all you need to do it is a philips head screw driver. This mod has been tested and is guaranteed to work straight out of the box.
