Description

Power your DIY builds easily with this Single 18650 Battery Holder Case. It’s a simple and reliable way to mount and connect a single 18650 Li-ion battery (3.7V nominal) in electronics projects. The holder features strong spring contacts for a secure fit and includes pre-attached lead wires—a red positive (+) wire and black negative (–) wire—so you can connect it quickly to your circuit, switch, or power module.

This battery holder is ideal for portable projects such as Arduino/ESP32 sensor nodes, small robots, LED lighting, test rigs, and IoT devices. Use it with a proper charging/protection circuit (recommended for Li-ion safety) when building rechargeable systems.
