Make your projects to go green this summer with our specialized USB/Solar Lithium Ion Polymer Battery charger! This charger is a very unique design, perfect for outdoor projects, or DIY iPod chargers. We've spent over a year testing and tinkering with this charger to come up with a plug and play solution to charging batteries with the sun and we're really plearnsed with what we ended up with.
Easy to use! Pick up any of our many 3.7V/4.2V LiIon batteries, and a 6V solar panel. Plug the battery into theBATTport using a 2-pin JST cable and the solar panel into the DC jack using a 2.1mm adapter cable Put the solar panel outside (and keep the battery out of the sun, it needs to be kept cool!) to start charging. You can power another project like a Mintyboost at the same time by connecting to theLOADoutput port
Our carefully designed charger is designed specifically for solar charging, and will automatically draw the most current possible from the panel in any light condition! Even thought it isn't a 'true' MPPT (max power point tracker), it has near-identical performance without the additional cost of a buck-converter. Other batteries may have different voltage, chemistry, polarity or pinout.
Comes with an assembled charger board, and a large stabilization capacitor that must be installed in your finished project.Does not come with a Lipoly battery or solar panelbut we do have tons available in the shop that work quite well. We have updated the design to be a little more compact, have nicer mounting holes,

• 3.7V/4.2V Lithium Ion or Lithium Polymer battery chargernt

• 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 Donent

• 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 sharingautomatically uses the input power when available, to keep battery from constantly charging/discharging

• Temperature monitoringof battery by soldering in a 10K NTC thermistor (not included) – suggested for outdoor projects where the battery may get hot (50u00b0C) or cold (0u00b0C).
