{"product_id":"pl4-prt-12885","title":"Sunny Buddy - MPPT Solar Charger","description":"\u003cp\u003eThis is the Sunny Buddy, a maximum power point tracking (MPPT) solar charger for single-cell LiPo batteries. This MPPT solar charger provide you with the ability to get the most possible power out of your solar panel or other photovoltaic device and into a rechargable LiPo battery. Set-up is easy as well, just plug your solar panel into one side of the Sunny Buddy and your battery into the other and you are good to start charging!\u003c\/p\u003e\n\n \u003cp\u003eThe output of the Sunny Buddy is intended to charge a single polymer lithium ion cell. The load should be connected in parallel with the battery. By default, the Sunny Buddy comes set to a maximum charge current of 450mA with a maximum recommended input of 20V (minimum 6V). Its recommended that batteries not be charged at greater than their capacity rating; thus, the smallest battery that should be charged with the Sunny Buddy is 450mAh.\u003c\/p\u003e\n\n \u003cp\u003eEach Sunny Buddy comes equipped with a LT3652 power tracking 2A battery charging circuit and pre-installed barrel jack and 2-pin JST connectors with unpopulated areas to install your own personal 3.5mm screw terminals for added input\/output options. This revision also adds a potentiometer to the input to set the holding voltage for MPPT and we've also tweeked the feedback resistors on the output to change the float voltage.\u003c\/p\u003e\n\n\u003cp\u003e**Documents:**\u003c\/p\u003e\n\n\u003cp\u003e* [Schematic](https:\/\/cdn.sparkfun.com\/datasheets\/Prototyping\/SunnyBuddy-v13a.pdf)\u003cbr\u003e\n* [Eagle Files](https:\/\/cdn.sparkfun.com\/datasheets\/Prototyping\/SunnyBuddy-v13.zip)\u003cbr\u003e\n* [Datasheet](http:\/\/cdn.sparkfun.com\/datasheets\/Prototyping\/LT3652.pdf) (LT3652)\u003cbr\u003e\n* [Hookup Guide](https:\/\/learn.sparkfun.com\/tutorials\/sunny-buddy-solar-charger-v13-hookup-guide-)\u003cbr\u003e\n* [Weather Station Tutorial](https:\/\/learn.sparkfun.com\/tutorials\/weather-station-wirelessly-connected-to-wunderground)\u003cbr\u003e\n* [GitHub](https:\/\/github.com\/sparkfun\/SunnyBuddy\/tree\/v13) (Design Files)\u003c\/p\u003e","brand":"SparkFun","offers":[{"title":"Default Title","offer_id":39690116399285,"sku":"PL4-PRT-12885","price":58.99,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0526\/9553\/1701\/products\/12885-01.jpg?v=1618121826","url":"https:\/\/getcahits.com\/zh\/products\/pl4-prt-12885","provider":"PuriLite","version":"1.0","type":"link"}
