Fuel gauge is a special type of accessory for lithium batteries that very precisely measures the state of the battery. This includes current voltage [mV], state of charge [%] and probably most interestingly: remaining capacity in the battery [mAh]. It is used with 1S batteries, and provides all this information via the I2C interface. On our board you can find qwiic connectors which allow I2C communication with microcontroller. Also, there is a JST input for any pouch battery you can find in our offer, as well as quick connect terminal connector for input if your source doesn't have JST connector. * For 1S batteries (4.2V) * Communication: I2C * Measures: voltage, state of charge, capacity * Dimensions: 38 x 22 mm / 1.5 x 0.9 inch https://elecena.pl/product/25316944/fuel-gauge-bq27441-breakout 2024-02-16
