Simply plug a USB-C cable into any USB power source and connect your battery via the JST connector — two LEDs show charging status at a glance (red = charging, green = complete).\n\nCharging uses a three-stage process: preconditioning, constant-current fast charge, then constant-voltage trickle charge to keep the battery topped up. The default 100 mA charge rate works safely with any battery size and USB port. For larger batteries (500 mAh+), solder the on-board jumper to increase the charge current to 500 mA.\n\nKey Features\n\n\nUSB-C Input – 5V charging from any USB-C cable and power source\n\nThree-Stage Charging – Preconditioning, constant-current, and trickle charge\n\n100 mA Default Charge Rate – Safe for all battery sizes; adjustable to 500 mA via solder jumper\n\nDual Status LEDs – Red (charging) and green (complete)\n\nJST Battery Connector – Standard 2-pin JST PH for LiPo/LiIon batteries\n\nBreakout Pads – 0.1\" pads for 5V, D−, D+, GND, and VBAT\n\nCompact Size – Small enough for desk use or permanent project mounting\n\n\nIdeal For\n\nCharging LiPo/LiIon batteries for portable projects\nWearable electronics with rechargeable batteries\nDesk-side battery charging station\nEmbedding in projects for built-in charging capability\n\n\nPackage Contents\n\n1× Adafruit Micro-Lipo Charger (assembled, ready to use)\n\n\n\nWarning: For use with single-cell 3.7V/4.2V LiPo/LiIon batteries only. Not compatible with older 3.6V/4.1V cells or batteries with different chemistry, voltage, or polarity. Battery not included.\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":4727,"title":"Default Title","sku":"AF-4410","price":12.55,"on_sale":false,"in_stock":true,"available_quantity":102,"option1":"Default Title"}]}
