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
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 LiPo (lithium polymer) battery is a rechargeable lithium battery widely used in portable projects because it is light and compact. LiPo cells need correct charging circuitry and careful handling to stay safe, so equipment that supports LiPo generally includes charging or protection hardware suited to 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.
