3.7v 2500mAh Li-battery

A 3.7 V lithium-ion polymer (LiPo) battery with a generous 2500 mAh capacity (~10 Wh). Thin, lightweight, and fitted with a 2-pin JST-XH connector for reliable connections to compatible chargers and development boards.

Includes built-in protection circuitry to guard against overcharging, over-discharging (cuts off at ~2.8 V), and short circuits. Output voltage ranges from 4.2 V when fully charged to a nominal 3.7 V.

Key Features

  • 2500 mAh Capacity – Approximately 10 Wh of energy storage
  • JST-XH Connector – 2-pin JST-XH (not JST-PH)
  • Built-In Protection – Overcharge, over-discharge, and short-circuit protection
  • No Thermistor – Charge at ½C or less (1200 mA max, 500 mA recommended)

Specifications

  • Voltage: 3.7 V nominal (4.2 V max, ~2.8 V cutoff)
  • Capacity: 2500 mAh (~10 Wh)
  • Connector: 2-pin JST-XH
  • Max Charge Rate: 1200 mA

Ideal For

  • Portable electronics and IoT projects requiring extended runtime
  • Powering single-board computers, microcontrollers, and sensor nodes
  • Any project needing a rechargeable, high-capacity power source

Package Contents

  • 1× 3.7 V 2500 mAh LiPo Battery with JST-XH connector
Warning: Only charge with a LiIon/LiPoly constant-voltage/constant-current charger at 1200 mA or less. Do not use NiMH, NiCad, or lead-acid chargers. Do not short, bend, crush, or puncture. Never charge or use unattended.
