Originally a conditioning charger for a 14.4V 2600 maH LI-ION/LI-POLYMER battery. The circuit board has a 100uh, 4.3A inductor, CTX100-2-52M, that is well worth the price of the board. With a little effort you can remove the inductor, 3 sets of header connectors, a MOSFET, two voltage regulators, two TO-220 aluminum heatsinks, three 330 uf 35v radial electrolytic capacitors.

Tiny Gold Mine for less than a Big Mac!
This board comes straight out of the Cadex UCC 1 Universal Battery Conditioning Charger.
**All Electronics CAT# BC-241**

The cool thing is, the three of these I bought all seem to work. I just connected the P1 header to a 24V power supply (GND is the inside pin) and it came to life with the different color LEDs on the flexible button panel.

Truth be told, I bought these for the components. Besides the beefcake inductor and the three capacitors mentioned in the description, I put the information about the other worthwhile bits down below.

ON MC7805ACT - +5V 1A Linear Voltage Regulator - (TO-220)

On one side of the LARGE HEATSINK:
National LM2676T-ADJ - SIMPLE SWITCHER Adjustable 3A Step-Down Voltage Regulator - (TO-220 7-pin)

The other side of the LARGE HEATSINK:
Fairchild FQP13N06L - 60V LOGIC N-Channel MOSFET (TO-220)

On the board itself:
Two (2) ON MBRD835L 8A 35V Schottky Barrier Rectifiers (DPAK SMT), what looks like a circuit breaker, as well as a 28-pin chip by the large header which I believe is some kind of CC-CV Battery Charge Controller, but I don't know which one exactly. There are countless other components too, but I don't care enough to bother with removing them.

Overall, this thing is a tiny gold mine for less than the price of a Big Mac! Just buy this goody bag and you wont regret it.

To get this charger to work all you need is a 10k ohm resistor NTC type and the batteries - the batteries do need the protection board
Once you hook these in the right place the charger will come on and work
There are no data sheet available online

If you need know how to hook it up
I will send All Electronic the photos what and where the hook need to go

The 24 pin part is a Microchip 18F873 controller. This design looks a lot like the Microchip reference design for an intelligent battery charger.

Still looking for spec sheet/hookup info
So I bought two of these along with a 14.8 v Li-Ion battery (LBAT-148) to charge with them... Still waiting for the spec sheet or hook-up information that was vaguely promised in the description. Applying 24v to the jumper and seeing the lights blink is nice, but where do I connect the battery I want to charge???
My real project is still on hold until I can charge that battery.
Can anyone give me more information than what is already here?

Needed a good quality Li-Po charger. Found this to be good for the price. Found a datasheet for this board that should be helpful to those in the comments section. I know it helped me.... https://plus.google.com/+Cadex/posts/YCWwvxtesKK
