Hi,
Using an LifePO4 12v, 20 ah and a SparkFun Buck-Boost Converter I am powering an arduino with a Lorawan connected sensor in a rural hard to reach area.
My question is: How can I measure the battery status and capacity so I can be able to read it from home? sending the status and measurement through Lorawan is not an issue.
Earlier I used a Li-Po battery with a baby sitter and using the battery gauge chip on the babysitter and I2C I would be able to check the status of the battery but no longer as now I am using a bigger LifePO4 12v, 20 ah battery.
