Hi,
The scenario i am working on is I have a car in storage that has 2 lithium-ion batteries. I have dedicated chargers (one for each)but the manufacturer recommends that the chargers not be left on despite it having what i believe is adequate voltage monitoring.
My plan is to purchase these ac outlets that have relay inputs: https://www.adafruit.com/product/2935?g ... CYQAvD_BwE
one for each battery.
I would like to monitor the voltage of each battery, and then if it drops below a certain value (around 12.8v in my case) I would turn the external surge strip on for that battery charger for 30 minutes and then re-evaluate. The code shouldnt be too bad but I am having trouble identifying the correct hardware to use. I have seen some devices such as an ina260 that I think would work, however, i need something more compact. I dont want to have project boards and several devices/boards all over the place. I would prefer a single gpio mounted board that can facilitate both the inputs and outputs required for this project. Does anything like that exist?
