Description

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.

Technical Specifications

For 1S batteries (4.2V)
Communication: I2C
Measures: voltage, state of charge, capacity

Super happy with this BQ27441 fuel gauge breakout! Knowing the exact state of charge (%) and remaining capacity in mAh for my 1S lithium battery projects makes power management so much easier. The Qwiic connectors made hooking it up over I2C a breeze with my microcontroller—literally plug and play. Plus, having both the JST input and the quick connect terminal block on the same board gives me awesome flexibility for different battery sources. Voltage readings in mV are spot on. Couldn't ask for a better battery monitor!
