Lithium Ion Polymer Battery - 3.7V 400mAh Ideal For Feathers

Lithium-ion polymer (LiPo) batteries are thin, light, and powerful energy sources ranging from 4.2V full charge to 3.7V nominal voltage. This battery has a capacity of 400mAh providing approximately 1.9 Wh of energy. It features a genuine 2-pin 25mm JST-PH connector with protection circuitry included for safe use.

This battery is custom sized to tuck perfectly between the headers on Adafruit Feather microcontroller boards and can be sandwiched between a Feather and FeatherWing, such as the Feather Huzzah ESP8266 with an OLED Wing. Use normal-height female or stacking headers (not shorty ones) for optimal fit.

The included protection circuitry prevents over-charging and over-use, cutting off at 3.0V voltage and protecting against shorts. Always use a LiIon/LiPoly constant-voltage/constant-current charger rated at 400mA or less, like Adafruit's Micro Lipo charger.
