Thanks again for the speedy reply! Super glad you turned on your machine!
Thanks for all the information it is really appreciated. I think this could be a really neat project. But, I would like to keep with your original idea of a simple BMS with keeping the costs as low as possible.
I am going to work on the voltage divider first, then the shunting. Just an FYI, I am jumping into the deep end. I have done a bit of simple circuit design. But, I love the idea of a challenge!
I was thinking it would be good to be able to shunt 1-2 amps max like your original design. Seems like that would be some serious heat at 15v which like you mentioned would need a complete rework of the shunting approach which most likely would include some sort of heat sink.
I took a look at the wiki, you don't happen to have a copy of the schematic file I could muck with do you? Or, maybe if you don't mind providing an editable file to Mark for the wiki?
