Adafruit USB/DC/Solar Lithium Ion/Polymer Charger
- 3.7V/4.2V Lithium Ion or Lithium Polymer battery charger
- Charge with 5-6V DC, USB or 6V solar panel!
- Too dark out? Use a USB mini-B cable or a 5V DC adapter
- Automatic charging current tracking for high efficiency use of any wattage solar panel
- Use any 6V solar panel
- Three color indicator LEDs - Power good, Charging and Done
- Low Battery Indicator (fixed at 3.1V) with LED output
- Set for 500mA max charge rate, can be adjusted from 50mA up to 1A by soldering in a resistor
- Will always draw the most current possible from a solar cell - up to the max charge rate!
- Smart load sharing automatically uses the input power when available, to keep battery from constantly charging/discharging
- Temperature monitoring of battery by soldering in a 10K NTC thermistor (not included) - suggested for outdoor projects where the battery may get hot (50°C) or cold (0°C).
- Board Dimensions: 41mm x 33mm x 2mm (1.6" x 1.3" x 0.08")
- Thickness with 2.1mm SMT Barrel Jack: 12.6mm / 0.5"
