100% Recycled Li-ion and Li-po Battery Charger
Intro: 100% Recycled Li-ion and Li-po Battery Charger
I'm gonna show you how, with a solder iron and some electrical tape and two hours, I turned two defunct electronic toys into full function, high end lithium ion battery chargers!
Try not to notice too much of the blur :-(
Both my real cameras are out on loan, so this was done with harsh technique.
a palm treo650, and a hand held magnifying glass.
Sorry.
When I get more "scrap" bluetooths and cameras, and have my multi-mega-pixel back... I'll add some clearer pictures. I promise. If you remind me :-)

STEP 1: Bluetooth Headset to Li-ion Charger
How you disassemble your bluetooth headset will depend on your model.
I used a Jabra that would drop phone connections at random intervals(VERY annoying).
My Jabra 150 is almost identical to the Jabra 350.

STEP 2:
Since Haraisuru did such a good job here I'll let that work stand.
But, to be fair, I'll include a few of my own images

STEP 3:
Let the modding begin!
I'll begin with the main body.
The goal is to move the battery external, and still be able to
hook it up for charging.

STEP 4:
And now for the Battery itself.
STEP 5:
Camera Battery charger.
This one was fun, as the $1 throwaway camera had an even better battery than the bluetooth.
Li-po battery to boot.
Turns out that after the thing is apart, it's even easier to mod.

STEP 6:
Camera to charger in a few easy steps.
STEP 7: The Step Where YOU Get to Help ME ;-)
Besides making my stash of white and Blue LEDs light up in remote locations, what else to do with these med-low capacity batteries?
oh ;-) I see a new pocket-sized instuctable contest is running.
Self-serving interest demands that, If you like my work,
then I have to ask you to consider voting for me.
I could use a new leatherman.
the one featured in my pictures has a snapped blade tip.
Speaks to the character of those tools, that it's STILL my favorite
utility blade, even with the tip missing.

The problem is... these circuits are set up for single li-po cells.
You didn't specify whether your plundered cells were 18650 li-ion, or true li-po. If they are li-ion.... about the only way you could use these circuits is to have 12 of them, and charge each cell outside your battery pack. A proper li-ion charger would not only chrge faster, but SAFER also! There is no thermal sensor doing it my way. Safety come from personal attention, and painfully slow chrge rates.
If the cells ARE laptop li-po...then you can either reuse the charge/balance/protection board from the laptop battery... or get/make a multi cell li-po hobby charger.

How did you solve this??

The OEM battery I saw when searching is 3600mAh @2.4v
Li-ion sits at 3.7(4.2v) and shouldn't be discharged below 3Volt(for safety)
It'll probably be just fine, but the controller WILL operate well below the safety voltage for the cell battery. Just remember to recharge it every once in a while, to prevent over-discharge(aka undervoltage).
I lucked out with my latest project...Cordless mouse/keyboard.
they both run on 3 AA batteries... and stop working at 3.1 volt... Perfect for swapping in Li-ion cells. The low-voltage cutout tells me that the circuitry was probably designed for Li-ion. UNfortunately, they're "generic" and the chips inside were no help identifying the manufacturer. Guess I get what I paid for(free from the electronics recycler drop-off).
