Datasheet

The Yellow LED is next to the microUSB connector and indicates when the battery is

being charged

The Green LED is also next to the microUSB connector and indicates when the

battery is done charging (all full)

Battery and USB connection

You can connect a battery to the breakout strip or to the JST connector. All of Adafruit

batteries come with JST cables that will plug in nicely so we strongly suggest that. Watch

the polarity of the cable!

The USB connector can be soldered on to create a portable 'USB power pack'. The two

data lines on USB have resistor dividers that match Apple charger values for 1A charge

rate so that you can plug any iOS device in to charge. 99% of other phones, devices and

tables are totally cool with these resistors as well. You can always short the D+ and D- lines

if you happen to have a phone that wants shorted data lines.
