SparkFun ESP8266 Thing - Battery fuel gage?

Wireless & IoT Wifi

Hi folks,

I am working on a board that currently uses a Battery Babysitter –

I am intrigued by the ESP8622 Thing –

but I’m wondering if/how I could get the same battery “fuel gage” functionality that the Battery Babysitter gives me. What are my options?

Kind regards,

Ihab Awad

Hi Ihab,

You could use this [LiPo Fuel Gauge in series with your battery connector. In order to keep it removable and easily connect to the battery circuit, I would recommend soldering a wire harness like [this or [this to the battery output pins on the Fuel Gauge and then connect the JST-side of the wiring harness to the battery connector on the ESP8266 Thing. After that, you just need to connect the I2C lines between the Fuel Gauge and the ESP8266 Thing.

We do not have an official SparkFun library for this fuel gauge but [this library could work. We have not tested it with an ESP8266 so there may be some adjustments you need to make to get it working with the Thing.

I hope this helps you find the right parts for this project. Let us know if you have any other questions or issues with the ESP8266 Thing or another SparkFun product in your project and we would be happy to help as much as we can.](Additional-files/TOL-10617 at master · SparkfunTechSupport/Additional-files · GitHub)](https://www.sparkfun.com/products/9914)](Jumper Wire - JST Black Red - PRT-08670 - SparkFun Electronics)](SparkFun LiPo Fuel Gauge - TOL-20680 - SparkFun Electronics)
