This board is for single prismatic cells and was designed to fit HiPower cells in the range 40-200ah.
This was the first board designed and is currently in use by myself in my PHEV Honda insight which uses 50 x 40ah cells.
It was originally designed to use the Picaxe 08M chip, but can now be used with Picaxe 08M chips or plain 12F683 pic chips according to your taste. It has on board programming pins for the picaxe chips system but does not support ICSP for pic chips.
Hardware
It can be used/constructed in a digital or analog configuration.
The digital configuration requires a Master Pcb but gives full individual cell voltage reporting and other features.

The analog configuration mimics some other simple lithum cell protectors and provides a high and low cell voltage opto ouput. It is not reccomended but included for completeness only.

Note the above software in blue does not contain or utilise the slave command functions.
The current software text file for the plain pic 12F683 digital pcb layout with commands is http://www.solarvan.co.uk/bms/PicMultiS ... 300510.txt
