Hi harlequin2!

This is great work on a simple BMS. Also a big thanks to you and sawickm (Mark) for putting this all on the Wiki!

I am woking on a project using 12v AGM 15ah batteries for a little scooter. I would love to use this design and see it added to the Wiki for a 12v lead AGM option. Seems that this application could be scaled up to any AGM / SLA (ah amount) series string amount.

You mentioned in one of your posts that all would need to be done is modifying the software in the PIC. Am I wrong but would you not also need a voltage divider on the input to scale from lets say 20v down to 5v to protect the PIC? The charts I have checked out for charging AGM's their CV is around 14.5 - 14.8 volts while the charging amps taper off.

I would love to be apart of making this happen if I can. You all have done some awesome work!

Doug
