Battery charge/discharg plot
Got a new 16-bit A/D. I connected it to the battery to measure voltage (blue plot) and to the 100A battery shunt to measure battery current (pink plot). Positive current is going to the loads (out o...

Yeah, both. I think the charge controller dropped down to 13.4V. Hooked up the A/D to a Arduino data logger around noon and turned on about 11A of loads to pull battery down. Once the loads were removed, the solar charged the batteries with 4.2A.
I'm able to measure both charge and discharge current because I'm using the ADS1115 in differential mode.

Why does the battery voltage start out at 13.4? Just completed charging or are you just showing off your new A-D?
