Where does the output get soldered to?
Trucker beat me to it LoL. How ya been Trucker? Busy summer, rolling up the miles?
My guess would be the charger fried the battery charging & monitoring chip and you will need to return the board. It could be coincidence, but I would be very wary of that charging tower and look at the output on a scope if you have access to one. An earth spike through the charger is also a possibility, but hard to confirm.I have a question for you all... I'll try to make this as short as possible, I plugged in my dna200 (2 cell 133w) Vaporflask to a new usb charging tower using a cable I'd been using on a 1a charger.
Something bad happened, and it wouldn't come back on. Clicking the fire button did nothing. Holding the fire button initialized the board, saw the welcome screens then check atomizer (no atty attached), then the battery screen flashed as empty and 0%.
Plugged it back into a known working charger and I had it set to show each cell voltage and usb amps, so it said 0 amps (no draw from usb) one battery as 0.00v and the other battery as 3.9v or something like that? So I thought maybe one battery discharged? I removed both batteries and charged them externally. Both went to full charge.
Replaced the batteries still wouldn't work. Plugged it back into usb charger, again saw 0 amps, 0.00v and something strange like 5.2v on the other cell (remember these are two 18650 Sony vtc5)
So I took the whole thing apart, checked connections, tried to using different batteries, something has absolutely gone wrong on the board, but I have no idea what. None of the components look any different from a new board...no scorching or anything like that.
It will talk to escribe, though I'm not sure what good that accomplishes of any?
Any ideas? Or has this board simply bit the bullet?
(Oh btw: the usb tower suffered thru this also, its led is now flashing always, and was constant on before. I have not been brave/stupid enough to plug anything else into it to verify it's function one way or the other but the led won't stop blinking on the usb tower)
Sorry for the long winded post.
Hey, Willie. I put "Kroil" to the acid test and it worked like a charm. I had some brass quick connect hose fittings that were stuck on the outside faucets, brass to pot metal, and the corroded to death over a couple of years. I didn't want to replace the hose bibs so I gave the a squirt or two of Kroil over the last week, basically whenever I remembered to anyway. They all came off smooth as silk! That stuff is great! Thanks for the heads up about it!
F that usb charging tower! Stupid thing messed up my flask! If it had messed up my erm+ I could have fixed it in 10 minutes.... A few screws, a few solder points, new board, boom... I'm back in business..... The flask has to be rebuilt... Extend the screen, extend the usb, major pain in my... Oh well.
