{"product_id":"sparkfun-battery-babysitter-lipo-battery-manager","title":"SparkFun Battery Babysitter - LiPo Battery Manager","description":"\u003cp\u003eThe SparkFun Battery Babysitter is an all-in-one single-cell Lithium Polymer (LiPo) battery manager. It’s half battery charger, half battery monitor, and all you’ll ever need to keep your battery-powered project running safely and extensively.\u003c\/p\u003e\n\u003cp\u003eThe Battery Babysitter features a pair of Texas Instruments LiPo-management ICs: a BQ24075 battery charger and a BQ27441-G1A fuel gauge. The charger supports adjustable charge rates of up to 1.5A, as well as USB-compliant 100mA and 500mA options. It also features power-path management, guaranteeing power to your project even if the battery has died. The self-calibrating, I\u003csup\u003e2\u003c\/sup\u003eC-based BQ27441-G1A measures your battery’s voltage to estimate its charge percentage and remaining capacity. It’s also hooked up to a current-sensing resistor, which allows it to measure current and power! It’s a handy IC to have, if you ever need to keep an extra eye on your project’s power draw.\u003c\/p\u003e\n\u003cp\u003eGet Started with the Battery Babysitter Guide\u003c\/p\u003e\n\u003cp\u003e\u003ciframe title=\"YouTube video player\" src=\"https:\/\/www.youtube.com\/embed\/u3KjOxiETWU?si=-70fY4zzwHMZZB7c\" height=\"315\" width=\"560\" allowfullscreen=\"\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" frameborder=\"0\"\u003e\u003c\/iframe\u003e\u003c\/p\u003e\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eLiPo Charger and LiPo Fuel Gauge combined into one board\u003c\/li\u003e\n\u003cli\u003eDIP-switch-selectable charge rates of 100mA, 500mA or 1.5A\u003c\/li\u003e\n\u003cli\u003eMicroUSB port for charging, or external options\u003c\/li\u003e\n\u003cli\u003eDynamic power-path management maintains a reliable output supply\u003c\/li\u003e\n\u003cli\u003eOn\/Off switch disconnects the battery for more power saving\u003c\/li\u003e\n\u003cli\u003e5V-tolerant I\u003csup\u003e2\u003c\/sup\u003eC interface to fuel gauge\u003c\/li\u003e\n\u003cli\u003eFuel gauge measures voltage, percentage, and current\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eResources\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eSchematic\u003c\/li\u003e\n\u003cli\u003eEagle Files\u003c\/li\u003e\n\u003cli\u003eHookup Guide\u003c\/li\u003e\n\u003cli\u003e\nDatasheet (BQ24075 Charger)\u003c\/li\u003e\n\u003cli\u003e\nDatasheet (BQ27441-G1 Fuel Gauge)\u003c\/li\u003e\n\u003cli\u003eArduino Library\u003c\/li\u003e\n\u003cli\u003eGitHub\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Sparkfun","offers":[{"title":"Default Title","offer_id":48624140910810,"sku":"ojp1789684416368","price":19.22,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0824\/8318\/3834\/files\/sparkfun-battery-babysitter---lipo-battery-manager_1.jpg?v=1789684420","url":"https:\/\/memoryfoamwear.shop\/products\/sparkfun-battery-babysitter-lipo-battery-manager","provider":"My Store","version":"1.0","type":"link"}
