could someone please post a pic of how to implement a kelvin connection to measure battery voltage directly at a 12v lead acid battery and connect that to a pic18f4523 controllers a/d?
I've attached my charge section and bvolts is from my battery but the voltage drop while charging is causing me to not accurately sense the real battery voltage.
should the a/d vref+ and vref- be connected at the battery terminals
via a 5v regulator?
I would really appreciate any help.
Thanks
Jamie
