{"product_id":"kitronik-battery-tester-project-kit","title":"Kitronik Battery Tester Project Kit","description":"\u003cp\u003eThis kit uses a single AA battery holder into which the user places a battery. LEDs then illuminate to show the remaining capacity of the battery. The circuit uses a quad operational amplifier to provide a reference voltage and comparators to determine which LEDs should go on. This makes it a great kit for studying operational amplifiers.\u003c\/p\u003e\n\u003cp\u003eTesting of the kit can be performed using an adjustable power supply or with our\u003cspan\u003e \u003c\/span\u003ecircuit tester\u003cspan\u003e \u003c\/span\u003e(consisting of an AA battery holder, variable resistor \u0026amp; crocodile clips).\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eDisplays battery charge level with 4 LEDs.\u003c\/li\u003e\n\u003cli\u003eGreat for showing how operational amplifiers work.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eContents:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e1 x\u003cspan\u003e \u003c\/span\u003ePP3 Battery Clip Lead (Heavy Duty)\u003c\/li\u003e\n\u003cli\u003e1 x\u003cspan\u003e \u003c\/span\u003e3xAA Battery Cage with Clip\u003c\/li\u003e\n\u003cli\u003e1 x\u003cspan\u003e \u003c\/span\u003eLM324 Quad Op Amp\u003c\/li\u003e\n\u003cli\u003e1 x\u003cspan\u003e \u003c\/span\u003eIC Socket 14 Pin\u003c\/li\u003e\n\u003cli\u003e1 x\u003cspan\u003e \u003c\/span\u003e1N4001 Diode\u003c\/li\u003e\n\u003cli\u003e4 x\u003cspan\u003e \u003c\/span\u003eRed 5mm Diffused LED – 275mCd\u003c\/li\u003e\n\u003cli\u003e1 x\u003cspan\u003e \u003c\/span\u003e680Ω Resistor\u003c\/li\u003e\n\u003cli\u003e5 x\u003cspan\u003e \u003c\/span\u003e220Ω Resistor\u003c\/li\u003e\n\u003cli\u003e4 x\u003cspan\u003e \u003c\/span\u003e22KΩ Resistor\u003c\/li\u003e\n\u003cli\u003e1 x\u003cspan\u003e \u003c\/span\u003e100KΩ Resistor\u003c\/li\u003e\n\u003cli\u003e1 x\u003cspan\u003e \u003c\/span\u003e1xAA Battery Cage with Leads\u003c\/li\u003e\n\u003cli\u003e1 x Battery Tester PCB\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eDimensions:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003ePCB Length: 68.5mm\u003c\/li\u003e\n\u003cli\u003ePCB Width: 38mm\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Kitronic","offers":[{"title":"Default Title","offer_id":48634245513444,"sku":"32KT2102","price":5.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0268\/7746\/0673\/files\/2102_additional_battery_tester_kit_parts.webp?v=1774990298","url":"https:\/\/www.elexp.com\/products\/kitronik-battery-tester-project-kit","provider":"Electronix Express","version":"1.0","type":"link"}
