Re: 14 Cell 12F1822 Slave Board for A123 28S3P Packs

Yes there is one at each end of pack.

Size is very close to the 16 cell slaves we did ages ago.

I'm using through hole parts.

14 Cell 12F1822 Slave Board for A123 28S3P Packs

Just a heads up. I have just finished a schematic for a special slave board to fit onto four OEM A123 28S3P pouch cell packs I bought recently. These fine 60Ah packs are about 100V each fully charged and comprise 20Ah A123 pouch cells in 3 parallel 28 series groups. http://endless-sphere.com/forums/...

Re: Maximite Master

Hardware creep :roll: and never ending project.

I bought a MM but am not going to buy another when we haven't used the original one yet.

Re: LTC6802 based 12 cell slave.

It basically works but i blew my 16x2 serial lcd while fiddling with my pack and haven't done any more.

I think the charger control side was the remaining part that needed tweaking. :?

Re: LTC6802 based 12 cell slave.

Good jobs the pics are tough :wink: Adapter is a nice easy solition. I think the issue with that JAL language is it's not well developed enough yet. With a BMS program you might never know if it was your program or the compilier/langauge which was causing a bug/crash/issue. Very frustrating and diff...

Re: Multi-Cell Slave-Version 2

I suspect they are unlikely to regard our BMS as suitable for there warranty terms but you never know. I would get it in writing in triplicate that they are happy if they agree. Good luck.
