Using the ADS1115 with Hall effect current sensors and to measure voltage practically isolated from the live 12/24V system.
I have make short addition to my documentation about my Yacht computer project, https://sites.google.com/site/olewsaa/ya...-raspberry about using a Hall effect current sensor with the ADS1115 in differential mode : https://sites.google.com/site/olewsaa/ya...all-sensor
Specially when using a sensor that yield the output as a voltage difference, zero voltage for zero signal end negative for one direction and positive for the opposite direction. This is exact what one want to monitor the battery bank. A nice benefit is that there is no danger in overloading a Hall effect sensor. The current only go through it's normal wire. The sensor will just be saturated.
As for voltage, I have updated a page that show how I suggest doing to to minise the problems in case of some short circuit or other stray currents.
