SparkFun will be closed Nov 26th and 27th for the Thanksgiving holiday. Orders placed after 2:00pm MT on the 25th will ship out Monday the 30th.
Description: LiPo 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 (and at the worst time). Don’t be caught by surprise next time your board suddenly powers-down! The SparkFun LiPo Fuel Gauge connects your battery to your project and uses a sophisticated algorithm to detect relative state of charge and direct A/D measurement of battery voltage. In other words, it tells your microcontroller how much ‘fuel’ is left in the tank. The LiPo Fuel Gauge communicates with your project over I2C and an alert pin also tells you when the charge has dropped below a certain percentage.

I’ve received my new fuel gauge in the mail just days after ordering. I am thrilled to say that it works great. I had previously purchased five of these from ebay and none of them worked. DO NOT BUY THESE FROM EBAY!! I can darn near guarantee that they will not work. All I did to make this work was connect the SDA, SCL, B+ & B-. Uploaded the same code I had used previously recommended by Arduino and written by Luca Dentella; http://www.lucadentella.it/max17043-libreria-per-arduino/
I will try the spark fun code some other time. I did this in just 3 minutes an am in a hurry to get back to other projects. Thank you Spark Fun!
