For many wearable projects we recommend a lithium-
polymer battery (http://adafru.it/328). These deliver 3.7
Volts — perfect for directly feeding low-power
microcontrollers such as the Adafruit Flora, yet enough
voltage to run a short length of NeoPixels.
Three alkaline cells (such as AA batteries) can be
installed in a battery holder (http://adafru.it/771) to
provide 4.5 Volts. Though larger and heaver than the
fancy lithium-polymer pack, they’re inexpensive and
readily available.
Four nickel-metal hydride (NiMH) rechargeable cells can
similarly be used in a 4-cell battery
holder (http://adafru.it/830) to provide 4.8 Volts.
Make sure you only use NiMH cells in this
configuration. Four alkaline cells (the disposable type)
will output 6V total — that’s too high for some
NeoPixels, and definitely too much for the
microcontroller!
Battery-operated LED project planning is discussed in greater detail in Battery Power for LED Pixels and
Strips (https://adafru.it/cDU).
