The 3.7V lithium batteries are commonly used in many projects. These batteries are a great way to power your projects. They're small, lightweight, and pack a pretty good punch for their size. Unfortunately, even the best batteries eventually run low on power, and when they do it's often unexpected. The remaining power and voltage of the lithium battery are highly nonlinear. We can only roughly judge whether the battery is full or almost empty according to its voltage.
The voltage of Li-ion or LiPo batteries doesnโt drop linearly. This is the reason why we need an accurate method to measure the battery percentage linearly. The MAX17043 LiPo Fuel Gauge connects your battery to your project and uses a sophisticated algorithm to detect the relative state of charge and direct the A-to-D measurement of battery voltage. In other words, it tells your microcontroller how much โfuelโ is left in the tank. The MAX17043 LiPo Fuel Gauge IC communicates with Arduino over I2C & tells Battery percentage and an alert pin also tells you when the charge has dropped below a certain percentage.
In this tutorial, we will interface MAX17043 LiPo fuel gauge Module from Sparkfun & Maxim Integrated with Arduino Pro Mini to measure the correct battery voltage & percentage of the State of Charge. We will display SOC & Voltage level on a 0.96" I2C OLED Display & use TP4056 to charge the battery.
