Description

Description

The Adafruit USB Li-Ion/Li-Po Charger is a smart single cell LiPo battery charger based on the MCP73833 chipset. Charging can be done from any computer USB port or USB wall adapter using a USB mini-B Cable. Charging is performed in three stages: first a preconditioning charge, then a constant-current fast charge and finally a constant-voltage trickle charge to keep the battery topped-up. The fast-charge current is 500mA by default, but is easily adjustable from 100mA up to 1000mA by soldering a through-hole resistor on-board. For people who require temperature monitors (using high charge rates), remove the 10K and solder in a thermistor in its place.

This board works well for DIY projects because it has 3 indicator LEDs – one for power, one for charging status and a third that indicates when charging is complete. Keep the battery connected to the charger and pass power through the additional JST connector using the included cable!

Please Note: For use with batteries we stock only! Other batteries may have different voltage, chemistry, polarity or pinout.


Features

  • 5V input via mini-B USB connector
  • Separate JST connectors for battery and load system so batteries don't have to be removed for charging
  • 500mA charge current, adjustable from 100mA to 1000mA by soldering in a resistor
  • 0.1″ (2.54mm) breakouts for the battery, DC, and status LEDs
