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.

Jargon buster

Plain-language definitions for the technical terms used above.

IoT
Short for Internet of Things, meaning physical devices that connect to networks or the internet to send data or be controlled remotely. It matters if you want projects such as connected sensors, remote controls or classroom data-logging activities.
LiPo
A lithium polymer rechargeable battery commonly used in portable electronics projects. It matters because LiPo batteries need correct charging circuitry and care, and this board includes hardware intended for that battery type.
pH
A measure of how acidic or alkaline a liquid is, on a scale where 7 is neutral. For a water monitoring kit, pH tells you about water chemistry and whether the included probe matches the range and accuracy your project needs.
