Description [Hide]

This is a Lithium Ion and Lithium Polymer battery charger based on the MCP73833. It uses a USB mini-B for connection to any computer or 'USB wall adapter'. 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.

This board is great 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!

For use with Lion / LiPo 3.7/4.2V batteries ONLY! Other batteries may have different voltage, chemistry, polarity or pinout.
 

  • Comes assembled and tested, includes a JST cable!
  • 5V input via mini-B USB connector
  • For charging single Lithium Ion/Lithium Polymer 3.7/4.2v batteries (not for older 3.6/4.1v cells)
  • 500mA charge current, adjustable from 100mA to 1000mA by soldering in a resistor
  • Separate JST connectors for battery and load system so batteries don't have to be removed for charging
  • Chip supports a 10K NTC thermistor which we have stuffed as a plain 10K. For people who require temperature monitors (using high charge rates), remove the 10K and solder in the thermistor in its place
  • 0.1" (2.54mm) breakouts for the battery, DC, and status LEDs
  • Free 2-pin JST cable included!
  • Batteries and USB cable not included.
  • Dimensions: 33mm x 35mm x 7mm (1.3in x 1.4in x 0.3in)
  • Weight: 5.7g ( 0.2oz)
