## Description

The Adafruit Mini Lipo with Mini-B USB Jack is a compact charger for single-cell 3.7V/4.2V lithium polymer and lithium ion rechargeable batteries. Plug in any Mini USB cable to a USB power source and connect your battery via the JST connector — two LEDs show status at a glance (red = charging, green = complete). For a USB-C version, see the Micro-Lipo Charger with USB-C. Charging uses a three-stage process: preconditioning, constant-current fast charge, then constant-voltage trickle charge. The default 100 mA charge rate works safely with any battery size. For larger batteries (500 mAh+), solder the jumper on the front to increase the charge current to 500 mA. Key Features Mini-B USB Input – 5V charging from any Mini USB cable and power source Three-Stage Charging – Preconditioning, constant-current, and trickle charge 100 mA Default Charge Rate – Safe for all battery sizes; adjustable to 500 mA via solder jumper Dual Status LEDs – Red (charging) and green (complete) JST Battery Connector – Standard 2-pin JST for LiPo/LiIon batteries Compact Size – Small enough for desk use or permanent project mounting Ideal For Charging LiPo/LiIon batteries for portable projects Wearable electronics with rechargeable batteries Embedding in project enclosures for built-in charging Quick battery top-ups from any USB port Package Contents 1× Adafruit Mini Lipo Charger with Mini-B USB (assembled and tested) 1× 2-pin JST cable (bonus) Warning: For use with single-cell 3.7V/4.2V LiPo/LiIon batteries only.
