18650 Battery Holder 3-Slot – Product Description

For anyone working with rechargeable lithium-ion batteries, having a reliable battery holder is essential. The 18650 Battery Holder 3-Slot is designed to safely house and connect three 18650 lithium-ion cells, providing stable electrical connections for your projects. Compact, durable, and versatile, this battery holder is perfect for electronics hobbyists, students, engineers, and makers who use 18650 batteries in DIY projects, Arduino boards, robotics, and portable devices.

What Is an 18650 Battery Holder?

An 18650 battery holder is a casing designed to securely hold cylindrical 18650 lithium-ion cells while providing reliable electrical contacts. Instead of soldering directly to the batteries, which can be dangerous, a battery holder allows easy insertion and removal of cells.

The 3-slot version can accommodate three 18650 cells side by side, offering the flexibility to wire them in series (increasing voltage) or parallel (increasing capacity), depending on the requirements of your project.

Key Features of the 18650 Battery Holder 3-Slot

• 🔋 Three-Slot Design – Holds 3 × 18650 rechargeable lithium-ion batteries.

• ⚡ Flexible Wiring Options – Supports series (for 11.1V nominal) or parallel (3.7V nominal with triple capacity).

• 🔒 High-Quality Construction – Durable ABS plastic body with nickel-plated spring steel contacts ensures solid connections.

• 🔌 Easy Integration – Comes with solder lugs or wire leads for quick and secure connections.

• 🔧 Compact and Portable – Ideal for DIY electronics projects where space is limited.

• ♻️ Safe and Reusable – Batteries can be swapped without soldering, reducing risks and improving safety.
