3.7v 180mAh Li-poly battery

3.7v 180mAh Li-poly battery

A compact lithium polymer battery perfect for small wearables, IoT sensors, and portable electronics projects. The 180mAh capacity delivers reliable power in an ultra-thin form factor, with built-in protection circuitry for safe operation.

Comes pre-attached with a genuine 2-pin JST-PH connector that clicks smoothly into matching jacks—no snagging or sticking like knock-off connectors.

Key Features

  • 180mAh Capacity – Approximately 0.6Wh total energy
  • Genuine JST-PH Connector – Smooth, reliable connection every time
  • Built-in Protection – Over-charge, over-discharge (cuts off at 3.0V), and short-circuit protection
  • Ultra-Compact – Only 4mm thick for space-constrained projects
  • 3.7V Nominal – 4.2V fully charged, 3.7V nominal output

Specifications

  • Capacity: 180mAh
  • Nominal Voltage: 3.7V
  • Charge Voltage: 4.2V
  • Cut-off Voltage: 3.0V
  • Connector: 2-pin JST-PH
  • Dimensions: 4 × 20 × 27mm

Ideal For

  • Wearable electronics
  • IoT sensor nodes
  • Small robotics projects
  • Portable devices
Safety Warning: Only use a LiPo constant-voltage/constant-current charger at 150mA or less. Do not use NiMH/NiCad/lead-acid chargers. Never charge unattended, short, bend, crush, or puncture. Always inspect for damage before use.
