Hi, I have a large battery pack + controller that indicates the state of charge with a 0-5 volt analog signal.
This is not the common measurement of the cell voltage, it is a calculated SOC from various measurements and it really is supposed to be a linear indication of SOC vs 0-5 volt output.
I am looking for some options to display this 0-5 volt signal. I found some 0-5 and 0-10 volt panel meters, both in analog and digital, but was a little surprised by the $100 - 200/ each price point for a good quality one.
I was thinking that something like a traditional segmented display would be fine, but these seems to use some kind of controller board chip and I am having difficulty figuring that aspect out, and frankly, don't want to build a board for it either.
It really needs something that can stand up to mobile use, not just sit on a bench.
Thanks
Harry
