A compact 3.7 V 350 mAh lithium-ion polymer (LiPo) battery with a short cable and genuine 2-pin JST-PH connector. The slim, lightweight form factor makes it ideal for wearables, IoT devices, and portable electronics projects.

The battery includes built-in protection circuitry that guards against overcharging (above 4.2 V), over-discharge (below 3.0 V), and output short circuits. The genuine JST connector clicks smoothly in and out of matching jacks without snagging.

Key Features

  • 350 mAh Capacity – Approximately 1.3 Wh of energy
  • 3.7 V Nominal – Output ranges from 4.2 V (fully charged) to 3.0 V (cutoff)
  • Built-in Protection – Overcharge, over-discharge, and short circuit protection
  • Genuine JST-PH Connector – 2-pin connector with short cable
  • Lightweight – Thin LiPo form factor

Specifications

  • Chemistry – Lithium-ion polymer (LiPo)
  • Nominal Voltage – 3.7 V
  • Capacity – 350 mAh
  • Connector – 2-pin JST-PH
  • Protection – Overcharge, over-discharge, short circuit

Ideal For

  • Wearable electronics and small IoT devices
  • Arduino, Feather, and microcontroller projects
  • Portable gadgets and prototypes
Safety Warning: Only use a LiIon/LiPo constant-voltage/constant-current charger at 350 mA or less (100–350 mA recommended). Do not use NiMH, NiCad, or lead-acid chargers. Do not short, bend, crush, or puncture the battery. Never charge or use unattended. Always check that your charger's JST polarity matches before connecting — reversed polarity can destroy the battery.

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.
microcontroller
A microcontroller is a small computer on a single chip that runs a stored program and controls connected inputs and outputs such as buttons, sensors, displays and communication interfaces. In a device built around one, it is the part that executes the code and coordinates the device's behaviour.
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.
Short circuit protection
A safety feature that helps protect the device if its output or wiring is accidentally connected in a way that causes excessive current flow. This matters in automation wiring because mistakes or damaged cables can otherwise destroy the sensor or power supply.
