Hi Tom George
I have had to place my batteries as is due to space being a factor..
The two banks of (6x 12v batteries) are wired with thick heavy heavy duty welding wire
The two banks sit side by side I've only got 1 wire linking the two banks
I might make additional wire and make it as if battery 1 on bank A and B are connected and battery 6 on bank A and B are connected.
Essentially what you have drawn above..
Anyways. I don't want to spend money on batteries and batteries would be 3 yr old or so.
I just want to build the kit.
So can I get some assistance with coding.
I'd also like to know if Arduino would accept one of the analog inputs being a negative value
I will start researching other projects with similar Arduino uses and see what I need to do
