Good news is coming. Testing is complete and boards have been ordered. :) I'm in the middle of creating a new thread. I'll post a link here.

The new version can be expanded to any number of cells, has a universal charge control circuit, balances at 5 amps, is about the size of a cigarette pack and will cost about $20 for a 16s board fully assembled.

Seriously, I think I've finally got it worked out good enough to get my official seal of approval.
It only took about 2 years and left a long stinky trail of burned components, blood, and enough circuit boards to reach half way around the world if placed end to end.

We'll start a new thread describing it soon.

His site went down a while back. I suggest sending him a pm.

Ok I know this thread has been put to rest for a while, but I'm just about to hook up a goodrum fechter v2.5 to my headway 24s pack, but I lost the paper sheet with instructions Andy sent me. Does anyone have the wiring instructions for my BMS?

Thanks

Increasing battery voltage and controller current limit will result in a non linear experience

Thanks for the PDF Icewrench. I've posted it online in case anyone else wants it: http://www.mediafire.com/?zvtlesx2cotuzb1

My BMS is slightly different, here's what the PDF has:

and my BMS:

more of mine:

The question I have is of the thin charger negative connection. Does my BMS board have that point somewhere or do I have a version that doesn't need it?

Yes, you need a jumper from the SW pad to charger negative when you are charging.

I am interested in building a 30 cell BMS
Could you provide me with a schematic for your 16 cell board.
And where can I buy a raw PCB
any info will help.
