• Comes assembled & tested with a free bonus JST cable!•5V input via PCB-style USB (Universal Serial Bus) connector• For charging single Lithium Ion/ Lithium Polymer 3.7/4.2v batteries (not for older 3.6/4.1v cells)•100m A charge current, adjustable to 500m A by soldering a jumper closed• Free 2-pin JST cable included!• For more details please click here for the datasheet Oh so adorable, this is the tiniest little lipo charger, so handy you can keep it any project box! Its also easy to use. Simply plug in the gold plated contacts into any USB (Universal Serial Bus) port & a 3.7V/4.2V lithium polymer or lithium ion rechargeable battery into the JST plug on the other end. There are two LEDs
- one red & one green. While charging, the red LED is lit. When the battery is fully charged & ready for use, the green LED turns on. Seriously, it could not get more easy. Charging is performed in three stages: first a preconditioning charge, then a constant-current fast charge & finally a constant-voltage trickle charge to keep the battery topped-up. The charge current is 100m A by default, so it will work with any size battery & USB (Universal Serial Bus) port. If you want you can easily change it over to 500m A mode by soldering closed the jumper on the back, for when you'll only be charging batteries with 500m Ah size or larger. For use with Adafruit Li Poly/ Li Ion batteries only! Other batteries may have different voltage, chemistry, polarity or pinout.
