Battery level - charge level - all in one

[Sci]

Hi all, take a look at the 2nd picture in this thread http://www.e-cigarette-forum.com/forum/battery-mods/54657-joye-510-m402-pcc.html.

I've got 2 of these PCCs, take out 3 screws(on the board) & it comes comes out. It has 2 wires that connect to the built in(charging) battery, & 2 that connect to the connector for the battery to be charged. Everything is built into that one small board. On the backside of the plastic is the batteries, 2 flat batteries stacked, not sure of the mAh of them.

My questions, can you hook another larger mAh(3.7v) battery to it & it still work?
Could you take it as it is and make a portable passthrough with it? In another thread someone(sorry, can't remember the nic) did it with a phone jump start/fast charger. I'm sure this is a much stronger battery.

It just looks like, to me, there is a lot of possibilities with this, the whole PCC will run you around $20 at absolutelyecigs dot com. If you know where you can get this same type circuitry in one single package like this for less, please let me know.

I'm not sure I'm following you. It has two wires that connect to the source battery, and 2 wires that connect to the socket for the battery that you want to charge. The circuitry doesn't put out enough current to run an atomizer.... not nearly enough.

What amount of current flow is produced to charge a battery?(An honest question)
Could you connect an atomizer in parallel to the charging circuit & charge an e-cig battery & vape at the same time?
The circuit board has a mini-usb connector also built in to recharge the onboard battery. So, could you charge the onboard battery, charge an e-cig battery & vape at the same time? A 510 passthrough with an inline battery kinda does that, right? You are vaping & charging a battery at the same time?
I hope I'm asking these questions right. I can visualize what I am thinking, but it doesn't seem to be coming out right in words.
Also, I fixed the wording on the original post(atomizer-connector for the batt 2 be charged).

You're asking the questions right.

The charging circuit probably generates about 150mA (.15A)... while an atomizer usually draws 1.5A+ (depending on the atty).

Take a look at the Bartleby. I believe it is just about exactly what you are looking for.

The Bartleby looks pretty kool, but I just got some KR808D-1s & am really liking them. Been vaping hard on the current cartomizer for 3 hours since the last refill!

Ok, I understand about the different current needs, so that means that the battery charging circuit is offering a very high resistance, correct? I=V/R. I've seen the ohm rating on various attys, wouldn't they pull what they need? If the atty & circuit board are parallel, you'd be getting a 3.7v drop across each & they would each pull the current they need based on the total resistance of the circuit?

I've moved the connector in one of the PCCs for my 401 & manual 401s & I think I am going to see if I can use one of the 808 usb charger connectors(they charge many different batts) as the connector for the other.
I was thinking about getting a couple more of these PCCs & see if the boards could be used for something else. I've got a couple of 3.7v - 2500 mAh li-ion polymer flat batteries(with pcbs) that I was thinking about using one of these circuit boards with. I've got a cigarette case big enough to hold it all, just trying to see what all I could make it do. I mean, they landed on the moon with less technology than you find in a modern calculator!

I put two 3.6v-1500mah cellphone batterys without the circuit boards in pariel in one of my latest modds getting 3.6v 3000mah and chargeing it through a 1/8 '' panel mount phone jack, chargeing it with a usb cord into a 1/8 '' phone jack plugin. Charged it out side in yard in case of explosion 1st time, aok no problums, getting 4.2v at full charge in less than 1 hour and last for 2 days on a charge. Have used it for over a week now and charged it several times and still no problums. Dont know if the circuit boards are for the phones use, batterys use or both? Just wondering how safe is my modd?
