Wow! Thanks for the quick reply. Okay, this makes sense in regards to dividing the input voltage and the shunt resistors. I am thinking dividing the input voltage by 4. Most AGM's operating range including charging is from 11v to 15v. So, this gives a range once divide of 2.75 to 3.75. Perfect for the operating range of the pic on your BMS!
The shunt resistors are two in series and then parallel? Looks like 1 amp per series string of resistors as the board has ~2 amps of shunting capability? I might be looking at that wrong....
What program are you using to make the schematics. They are *.gbr files on the wiki. I have some time right now so thought I could work on this.
