WebJun 3, 2024 · When a device wants to query the battery data, which it does quite regularly, it pulls the line low in a specific pattern. The Gas Gauge IC then does the same, responding with the requested data. The communication is therefore bidirectional, and relies on the line being high in an idle state. WebNov 4, 2024 · If you put a voltmeter in parallel with the ammeter you'll see that the voltage is very depressed. What you need to do in order to measure maximum current available is to measure it through a variable resistor while also measuring voltage across the battery. i swapped my brother on the internet reviews
