MakerFocus 4x 3.7V 3000mAh LiPo Batteries with Protection Board & JST 1.25 Plug for ESP32 – Mesh Node Kit

Compact, ready-to-use LiPo power for ESP32 and mesh nodes

The MakerFocus 4‑pack brings four 3.7V, 3000mAh LiPo cells paired with a protective board, insulated rubber tape, and a JST 1.25 plug. This kit is designed to streamline power for ESP32 development boards, wireless mesh nodes, and portable prototypes, offering a tidy, compact power solution that fits small enclosures and mobile setups.

With an emphasis on practical usability, the set aims to deliver stable energy for your projects while helping you manage wiring and assembly cleanly. By including insulation materials and a plug for easy connections, it reduces setup time and uncertainty when you’re prototyping or moving from a bench to a field environment.

What’s included

• Four 3.7V 3000mAh LiPo cells
• Protection board integrated for safer charging and discharging
• Insulated rubber tape for secure, tidy insulation
• JST 1.25 plug for simple connections to ESP32 boards and modules

Charging, protection, and safe handling

• Charging Method: The recommended charging current is 0.6A, and the maximum should not exceed 1.5A
• Overcharge Protection: When the battery reaches 4.2V, the protection board automatically powers off to stop charging
• Over-discharge Protection: If voltage drops to around 3.0V, the protection board stops discharging to help preserve the cell
• Short Circuit Protection: In case of a short, the protection board shuts down within milliseconds

Note: Overcurrent protection has limits. Avoid sustained high-current charging or discharging beyond the specified range to reduce stress on the protection system.

Real-world use cases

Ideal for compact ESP32 development setups, battery-powered sensor nodes, and lightweight portable electronics. This kit supports agile prototyping, field testing, and small-scale mesh networks where a dependable, space-conscious power source matters.

Why choose this kit

If you need a ready-made, integrated battery solution with protective features and simple wiring for your ESP32 projects, this MakerFocus kit offers a practical balance of capacity, safety features, and ease of use. Benefits are presented as possibilities to enhance your workflow, not guarantees.
