Chip in e-cigarette battery.

The manufacturer may have slipped up on the house coded chip.

In one unit the chip was marked; 3417WA, in the other it was marked; Esmoke33716M.

Its probably going to be hard getting Google to find just a base number with no prefix - someone might just happen to know.

Thanks for any help.

The better thing to do is put that E device in the garbage where it belongs

No one needs them, just like the real thing, they don't need them ether...

You have to be born cool.

No amount of toys, tattos, ear rings, nose rings, tongue studs, ripped trousers, paints hanging down to the knees with or with out suspenders, mohawk died or plain, mustache: plain or handle bars, strange glasses, induced lasherations, needle sharing, drug popping, nose candy, getting beer cans and apples shot off the top of your head from a drunk friend via a bow and arrow, smoking the tires off your car, blowing the engine infront of your friends, doing the highest jumps with a bike etc,. will make you COOL..

Did I miss something ?

Now of course, If you had a dame that everyone wanted, you then maybe COOL!

Candy cigarettes. Those have not been banned by the nanny-staters yet.

At the end of the day; that chip is a lithium cell charge controller.

Most of my home brew lithium chargers require supervision, the charge board from an e-cig can be left to get on with it - even if it takes a long time to charge a decent sized cell.

I couldn't find anything on the specific chip. I suspect it's custom and well protected. This should help explain what's going on inside:

As for e-cigs and vaping, I don't indulge and see no value in breathing fumes. However, a friends son got involved with the vaping scene and has demonstrated to me that there's plenty of demand and money available. They're generally banned in public places, which I guess adds to the mystique. Judging by the consumption of 18650 LiIon batteries, e-cigs have not only helped lower the price of these batteries, but have greatly contributed to my growing collection of half-dead 18650 cells. If you read candlepower forums or the various e-cig forums, you'll find plenty of discussion about which batteries are best (or cheapest). That gets my attention.

Yes, with the added bonus of a puff counter and copy protection system:

I've been experimenting with fast charging 18650 cells at 4A. So far, I've confirmed that I can charge at the data sheet rate without damage but only if I keep the cell cool and not try to get too close to 100% charge. The quality of the cell also makes a big difference. The typical "Fire" type cells are junk and are rarely capable to meeting their stated capacity (ma-hr). Therefore using a data sheet max charge rate is the same as charging too fast. I've destroyed a few cells verifying the problem. Also, heavily used cells are at reduced capacity, which also requires a reduced fast charge current and time. In other words, you don't have to wait a long time for it to charge, but only if you know the capacity and can control the temperature. I use a water bath, but that's not suitable for General Public.

Yes. Nerds are often considered cool. I'm the consummate nerd, geek, and hodad all my life. For many years, this was anything except cool. The women would hang around with the sex athletes and those with the cool toys and just make fun of the nerds. Then, we all grew up together. Today, I'm being chased by about 5 women (I sometimes loose count). Their lives with the sex athletes and toy collectors have turned into life with a viagra addict and bankruptcy. Suddenly, nerds are starting to look very interesting. After about age 45 and when the kids are gone, I'm now the major attraction. As an added bonus, I don't smoke or vape, so I might survive a bit longer than most.

The ones I've been doing so far are basically a TL431 shunt regulator - there are various ways to boost the current rating with external transistors.

Nothing bad has happened yet - but I take care not to leave them charging too long.

The current experiment is charging a 3x3 18650 laptop pack.

The charger is an 8uF wattless dropper on 50Hz, no safety circuits - so it can only be on charge while I'm there monitoring it. 3 sessions so far, and its only up to 11.8V.

It (was) a Vapestick and doesn't look that sophisticated. 2 of the units had batteries that didn't take any charge current, the 3rd one still lit its LED when the button was pressed so I didn't scrap it.

It ain't nohow personal.

Widowed (or reasonably divorced) single heterosexual males over 45, who are also financially viable, are in short supply. First, women live longer than men, statistically, and second most men in that demographic are married.

There is a widowed gentleman down the street from us, entirely normal looking, but with a good job, and also a pet owner. He also seems to be fighting them off - and with good humor. He blames his black lab.

Tobacco users are worse then lepers. Lepers can be cured.

Freudian slip. I'm only being chased by a few loose women. Remind me to have a talk with my proof reader.

Be happy that you don't live near 'The Villages'.

This one in Florida? I'm old enough to collect socialist security, but not quite old enough to want or need a retirement community. If it's anything like a US version of "Midsomer Murders", where homicidal geriatric players act like testosterone powered teenagers, it's not for me. I'm quite happy to continue my life of decadence and debauchery without being surrounding by a community of like minded individuals.

They brag about their golf courses, amateur radio clubs and computer clubs, along with about 100 other private clubs. The place is crawling with old women looking for a man. I live about 10 miles away, and I hate to even go to the grocery store. When a woman calls you a youngster, and you are in your mid 60s, it's time to flee!
