MakerFocus 2pcs 3.7V 3000mAh LiPo Battery with Protection Board for ESP32 Mesh Node T114

Compact Power for ESP32 and Mesh Node Projects

Meet the MakerFocus 2 pack of 1S LiPo batteries built for compact electronics. Each cell delivers a steady 3.7V nominal voltage with a robust 3000mAh capacity, offering a reliable power source for prototyping and small deployments. The kit includes a protection board, insulated rubber tape, and a JST 1.25 plug to simplify integration with ESP32 development boards and mesh nodes like the T114. The design emphasizes a clean, secure fit in tight enclosures, while the included essentials make setup smoother for quick testing and iteration.

Designed with real world use in mind, these batteries can power microcontrollers, sensors, and wireless modules during early development stages. The dual pack format supports convenient swapping in field tests or weekend tinkering, and the JST plug helps make clean connections without awkward wiring. The materials and assembly are chosen to support durable, repeatable testing across multiple sessions, whether you are sketching ideas or refining firmware and network topology.

Key Benefits at a Glance

• Two 1S LiPo cells deliver a compact power solution suitable for ESP32 boards and small nodes.
• Protection board provides safety features that help prevent common battery mishaps during development.
• Preinstalled insulating tape offers a tidy setup and reduces bare contact risks in crowded enclosures.
• JST 1.25 plug enables straightforward, reliable connections to your development board or project harness.

As you prototype and iterate, the combination of a 3000mAh capacity and a protective circuit can keep prototypes running longer between charges, while the compact footprint helps you preserve space inside compact enclosures. It is a practical choice for hobbyists and professionals exploring ESP32 based sensors, actuators, or mesh networking experiments.

• Install the pack into ESP32 development environments to sustain continuous testing of firmware and network behavior.
• Use in mesh node projects where a light yet dependable power source is beneficial for field trials and parameter tuning.
• Pair with insulated tape and the JST connector for clean assemblies in compact enclosures or prototyping hatches.

Charging method and limits are provided to support safe and predictable behavior during testing. The recommended charging current is 0.6A, with a maximum not to exceed 1.5A. For discharging, aim for a 0.6A rate with a hard maximum of 1.5A. These ranges are designed to balance performance with protection while you iterate ideas and test code.

Important safety notes ensure responsible use. The protection board automatically stops charging when the battery reaches 4.2V and halts discharging when the cell voltage drops to 3.0V. In the event of a short circuit, the board responds within milliseconds to cut power. The overcurrent protection is not a catchall, so avoid sustained currents beyond the specified range to prevent board damage.
