Can tell you this gleaned from reading data sheets and manual this is a little more than just the basic. I wager there is a pic processor and some form of non volatile memory. It handles all the sampling and data storage like a daq system. It is also doing all the math and remaining battery capacity based on known formulas. The app is just downloading that data and displaying in a fancy display. There are parameters that are set with the app writing to the battery monitor. These are battery capacity and shut size if used.This device should be called an intelligent battery state of charge monitor.
Most Bluetooth battery monitors either just monitor voltage or if they do measure current they measure it at 100 amps or less. Yes it is easy and cheap when you are at that level with the chip devices listed earlier. That is the way the RC battery gauges are made. Nothing new there.
Since this for automotive applications I have to measure in the 500-600 amp range for measuring during cranking and being able to ACCURATELY measure battery state of charge. No sense in limiting current measurement range at 100 amps. Everytime your cranked it you pegged out the range for those few seconds with more than 100 amps drawn. You can't determine wattage used without an accurate amperage measurement.
