Junk. I bought a 3A version. For one thing you will need to get unprotected cells. The charging input is a DC jack, so I had to make a cable. Simply as a charger it only took the cells to 4.11V. I was using/testing it with a PT, it was providing about ~2.7A with a DCC and that's fine.
One day a week later though nothing, I guess I failed to note the directions, I hit the reset a couple of times with the charging cable plugged in and smoked it.
WTH you talking about??? And what kind of desirable features do $12 meters have?
...I printed your schematic, laid out the parts on it... some of the parts aren't breadboard friendly so I'll have to touch some temp leads on...I'm more concerned with the perf board layout, thinking I may just jump right in and get the stuff to make my own pcb (if you have a design for that cct say in a pdf or jpg or what ever I can scale onto a piece of board?)...my plan is to mount 3 of those ball tact switches on the back of the pcb so it's one complete modual...however, I've got 2 buddies that are vaping now that have come to the realization that their eGo T's don't seem to be as good as the things I make (I told them, do they listen?) so I'm working on a couple boxes for them, once that's done...
