DFRobot provides you with a compact and efficient 7.4V lithium battery USB charger, only the size and weight of an ordinary Gravity sensor. With just a mobile phone AC adapter (or power bank) and an Android data cable, you can safely and efficiently charge the 7.4V lithium battery up to 1A, which commonly used in various robots and motor drivers. The light-weight and micro USB interface features make it ideal for outdoor applications. In addition to serve as a charger, it can also be embedded in a variety of 7.4V lithium battery-powered projects, adding a USB charging function to it, eliminating the need for battery swapping and the use of traditional bulky power adapters.Board Overview \n  \n\n\n\nUSB Charger for 7.4V LiPo Battery Board Overview Connection Diagram \n  \nUse a mobile phone AC adapter or power bank to charge lithium battery\n \n\n \n\n\nFEATURES\n\n \n\n \n\n\nHigh efficiency boost type USB charger, designed for 7.4 lithium battery\nCharge input and battery port reserved pads for easy modification and measurement\nAll-round protection of battery and power supply\nMultifunction LED status indicator, system status at a glance\nUSB ESD shell\n\n \n\n \n\n\nAPPLICATIONS\n\n \n\n \n\n\nRobots and motor drivers\nLithium battery charger\n\n \n\n \n\n\nSPECIFICATION\n\n \n\n \n\n\nCharge input voltage (USB IN)：3-6V (5V, typical for USB IN)\nBattery input (BAT IN): 7.4V 2s cells Li-polymer/Li-ion battery\nMaximum charge current: 1A trickle charging, constant current, constant voltage three phases charging\nCharge cutoff voltage: 8.4V±1%\nCharge efficiency: >90%\nProtections BAT IN: over charge/reverse connection protection USB IN: adaptive input current limitation, over heat/reverse connection protection\nOperation temperature: -40℃～85℃\nDimension: 28.0mm*37.0mm/ 1.1 * 1.46 inches\n\n \n\n \n\n\nDOCUMENTS\n\n \n\n \n\n\nProduct wiki\nMore Documents\n\n\n","vendor":"DFRobot","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":5567,"title":"Default Title","sku":"DF-DFR0564","price":8.54,"compare_at_price":0.0,"on_sale":false,"in_stock":true,"available_quantity":180,"option1":"Default Title"}]}
