Product Description
Conditioning charger for a 14.4V 2600 maH LI-ION/LI-POLYMER battery. Removed from new equipment.

The parts on the board including a 100uh, 4.3A inductor, CTX100-2-52M, are well worth the price. 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.

CAT# EX-57

Reviewer: from Atlanta, GA

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....

Tiny Gold Mine for less than a Big Mac!

Reviewer: from DENVER, CO USA

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

Bountiful Recovery

Reviewer: from COLTON, SD USA

My first disassemble wasn't as good as my recent ones. If you'd like to recover ALL the parts, I've some tips. I use a Triton soldering tool to remove the inductor and small heatsink. It gets red hot to melt the soldered board joints quickly so you can get these off...a tiny screwdriver gets it started. Take out the 330uf capacitors and be sure to remove the mounting screw that holds the N MOSFET and Switching regulator.
Then remove the white plastic headers working them straight up and off.
Now hot air is all you'll need to take everything off. It was my discovery TO220 devices come off quickly if you heat the pins from the top of the board instead of below it. I've programmed the 16f873 with the SUPER PROBE software (Mondo) though haven't made boards yet.

Reviewer: from La Habra Heights, Ca.

I’ve provided 24 volts to pin 1. The pins out close to pin 1 has constant power. There are 7 pins. Starting at left closest to oin2: pin 1 is negative. Pin 2 4.8 volts. Pin 3 2.3 volts. Pin 4 4.8 volts. Pin 5 4.8 volts. Pin 6 4.8 volts. Pin 7 0
(Zero) volts. I’m not sure how to hook this up as a battery charger and I’ve contacted the manufacture but they don’t want to discuss anything about anything it might have to do with her proprietary information. Do you guys think it might be possible To add up several of the pens and run them in series and use them as either a LED driver or a power supply? Is anybody got any information yet on how to use this thing is a battery charger and wish pens you use to charge a battery?
