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

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

A compact lithium-ion polymer battery custom-sized to fit perfectly between the headers on Adafruit Feather boards. With 400mAh capacity and a short 25mm JST-PH lead, it can even be sandwiched between a Feather and FeatherWing.

Features a genuine 2-pin JST-PH connector with built-in protection circuitry against overcharging, overdischarge (cuts out at 3.0V), and output shorts. All Adafruit Feathers charge this battery at a safe rate.

Key Features

  • Feather-Optimised Size – Fits perfectly between Feather headers
  • 400mAh Capacity – ~1.5Wh total energy
  • 3.7V Nominal – Standard LiPo voltage (4.2V max)
  • Short 25mm Lead – Tidy fit in compact builds
  • Genuine JST-PH Connector – Reliable, smooth connection
  • Built-in Protection – Overcharge, overdischarge, and short circuit

Specifications

  • Capacity: 400mAh
  • Nominal Voltage: 3.7V
  • Charge Cut-Off: 4.2V
  • Max Charge Rate: 400mA or less
  • Lead Length: 25mm
  • Connector: 2-pin JST-PH

Ideal For

  • Adafruit Feather projects
  • Feather + FeatherWing stacks
  • Compact IoT devices
  • Wearable electronics

Package Contents

  • 1× Lithium Ion Polymer Battery 3.7V 400mAh
Tip: Use normal-height female headers (not short ones) when sandwiching this battery between a Feather and FeatherWing.
Safety Warning: Only use a LiIon/LiPoly constant-voltage/constant-current charger at 400mA or less. Do not use NiMH/NiCad/lead-acid chargers. Do not short, bend, crush, or puncture. Never charge or use unattended.
