On your phone, there's a little image of a battery cell that tells you the percentage of charge - so you know when you absolutely need to plug it in and when you can stay untethered. The \u003cstrong\u003eAdafruit LC709203F LiPoly \/ LiIon Fuel Gauge and Battery Monitor \u003c\/strong\u003edoes the same thing. Connect it to your Lipoly or LiIon battery and it will let you know the voltage of the cell, it does the annoying math of decoding the non-linear voltage to get you a valid percentage as well!\u003c\/p\u003e\u003cp\u003eSince this nice chip is I2C, it works with any and all microcontroller or microcomputer boards, from the Arduino UNO up to the Raspberry Pi. And you don't have to worry about logic level, as the gauge runs with 3.3V or 5.0V power and logic equally fine. Please note this chip uses I2C clock stretching, on Raspberry Pi Zero\/1\/2\/3 you will need to slow down the I2C port.\u003c\/p\u003e\u003cp\u003eTo use, Lipoly or LiIon battery to one of the JST 2 PH ports (either one). Then use the included JST PH jumper cable to connect to your boost converter, Feather, whatever! Use the I2C interface and our Arduino or CircuitPython\/Python library code to set the pack size (this helps tune the calculation) and read the voltage and percentage whenever you like. If you connect a 10K thermistor to the THERM pin you can also use it to read the battery pack temperature - our packs do not come with a built in thermistor but many do.\u003c\/p\u003e\u003cp\u003eTo get you going fast, we spun up a custom made PCB in the \u003cstrong\u003eSTEMMA QT\u003c\/strong\u003e form factor, making it easy to interface with. The STEMMA QT connectors on either side are compatible with the SparkFun Qwiic I2C connectors. This allows you to make solderless connections between your development board and the LC709203 or to chain it with a wide range of other sensors and accessories using a \u003cstrong\u003ecompatible cable\u003c\/strong\u003e.

Behold! A holder for three (3) AA batteries! It's got a 6\" long genuine JST-PH 2-pin cable connector, an On\/Off switch, and, oh yes, it's in classy Adafruit black.\u003c\/p\u003e\n\u003cp\u003eThis battery holder connects 3 AA batteries together in series for powering all kinds of projects. We spec'd these out because the box is compact, and 3 AA's add up to about 3.3-4.5V, a very similar range to Lithium Ion\/polymer (Li-Ion) batteries, plus it has a nifty on-off switch. That makes them ideal for use with 3.3V projects that have a 2-pin JST connector meant for one of our Li-Ion\/Poly batteries. (Of course, you can't recharge them like Li-Ion\/Polys, so don't try to plug this into one of our Li-Ion\/Poly charger boards!).\u003c\/p\u003e\n\u003cp\u003eFits any standard AA battery. When using rechargeable NiMH the output voltage will range from about 3.7V with charged batteries to 2.7V at the end of life with a nominal voltage of 3.6V. When using alkaline cells, the output will range from 4.5V with new batteries to 3.3V at the end of life with a nominal voltage of about 4.5V.\u003c\/p\u003e\n\u003cp\u003eThe polarity matches that of our 2-pin JST cable and Li-Ion\/Poly batteries.
