How about a larger capacity battery: SparkFun Electronics - Polymer Lithium Ion Batteries - 2000mAh
Yeah was thinking to step it up to that one. Would need a 4 aa box or applicable project enclosure. That and I hadn't read the sheet yet to see if that one has built in protection like the other one. Could also pair up that charger with a 14500 or slightly bigger batt with tabs to hook a jst cable to to be able to just clip everything together.
Ok I checked it is protected

According to the datasheet li-poly or li-ion would work. I'm really thinking about incorporating warp1900's quick change adapter solution

I wouldn't say 'fan', but it's a smart solution for gaining interoperability, particularly for those who like to use different atty types.
i don't get it
I'm not a fan of anything; that's just for teenagers with their pop groups, and football fans.
So it looks like with stevo_tdo's charger board from Sparkfun, one could get, (with the addition of a switch and some diodes) 5volts, 4.2volts, or battery voltage??
"Multi-Volt"...Nice!
It's a nice board that uses a good chip. And I like that the webpage links to all the documents.
2 issues.
First, re USB input: it states that the current draw is limited to 100mA in case the usb input is unpowered; such as connecting a mobile phone as power source I guess. This is a bit silly. But the board could be modified quite easily to get around this.
Second, and this is a bigger worry. The chip datasheet (http://pdfserv.maxim-ic.com/en/ds/MAX1551-MAX1555.pdf) says it is for Li-ion and doesn't mention anything Li-po. At this point not sure if this board really can be used to charge both types. It might well be true, but need a bit more convincing. Certainly for Li-ion it looks good.
This is the best I could find for you kinabaloo.

Yeah, usb is what most people would want to use. I have a wall block that outputs 5v that would then charge at a rate of 280. Of course still looking for better options. Always looking.

What worried was the chip rather than board. In general the chip datasheet talks only of Li-ion, but there is one mention of Li-po in a table in the document.
This board is a bit expensive; but if it can charge LI-po also, and uses a good chip, perhaps worth it.

I figured i'd bite the bullet and go with the pre made board. I'm sure on the next round of my mods i'll get into building a board around the chip or similar chip. Beings these chips are inexpensive and that would cut the overall price of the project down considerably.
Let's go off topic for a moment here. Now i'm on a atomizer/cartridge quest. I love the flavor and vapor from my m401 standerd 4 hole atomizers and hate the cartridge life. Was thinking of going with a 801 atomizer/cartridge though. Obviously large cartridge life, but what about flavor, vapor, etc. Or at the same time is there another cart that would fit my m401 atomizers.
