Overview

Product Overview

4 x 18650 battery holder box with wire is a compact 4-cell battery carrier for securely mounting 18650 lithium-ion batteries and bringing power out through attached leads for DIY electronics projects. Designed as an easy power solution for portable builds, it lets you connect removable cells to prototyping boards, LED lighting, robotics, home automation devices, sensor nodes, and other embedded systems. This wire-lead battery case is useful for custom battery packs, bench testing, repair work, and Arduino, Raspberry Pi, or ESP32 power experiments where a replaceable battery holder is preferred, while the no-cover design keeps cells accessible for quick swaps, inspection, and maintenance.

Questions & answers

Frequently asked questions

It can be used in Arduino, Raspberry Pi, and ESP32 power experiments, but it is only a battery holder with output leads. Use the correct power regulation, protection, and connection method required by your board.
Yes. The holder includes attached wire leads, so the battery pack output can be connected to a prototype circuit, terminal block, switch, or converter without soldering directly to the cells. You may still need a connector.
This is a passive 4-cell 18650 carrier with positive and negative wire leads. It does not function as a charger, voltage regulator, or battery management system, so add appropriate external circuitry for your project.
It suits portable electronics where removable cells are useful, including LED lighting, robotics, home automation devices, sensor nodes, bench testing, and repair work. The open design makes cell swaps, inspection, and maintenance easier.
Check that all 18650 cells are inserted in the correct orientation, charged, and making firm contact. Also verify wire polarity and confirm your circuit or converter accepts the holder’s battery output before connecting sensitive boards.
