This is a super mini Solar Lipo charger based on the CN3065 - a single lithium battery charge management chip. This 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 Solar charger and your battery into the other and you are good to start charging! The output of the Solar Charger is intended to charge a single polymer lithium ion cell. The load should be connected in parallel with the battery. By default, the Solar charge comes set to a maximum charge current of 500mA with a maximum recommended input of 6V (minimum 4.4V). It's recommended that batteries not be charged at greater than their capacity rating.<br><br>color: blue Material: PC + metal Solar panel input: 4.4-6V Max charge current: 500mA Interface: 2-pin JST connectors(or PH2.0) Short circuit protection Continuous Charge Current Up to 500mA Battery status indication ( Red : Charging , Green: Charged ) Support USB Charge (Micro-USB Connector) Size:2cm x 4cm<br><br>Package Contents:1 x module<br><br>Only the above package content, other products are not included.
