Single-cell holder for one 18650 lithium-ion battery, with two 6-inch bare wire leads for power and ground. Embossed polarity marks for correct orientation.
Description (4 lines) This is a plastic holder designed for one standard 18650 rechargeable lithium-ion cell, allowing quick and easy integration of 18650 batteries into robotics, prototyping, and general DIY electronics projects. It’s constructed from high-quality ABS plastic for durability and safety, with embossed polarity marks (+/-) clearly identifying correct orientation to prevent reverse-polarity connection. The holder comes with two 6-inch cables, each terminated with bare wire leads, ready for direct connection to a circuit, charging module, or power management board — no soldering required for the battery itself, though the wire leads will need to be connected to your circuit.
