1X 18650 1S Battery Holder Case Box with 6" Wire Leads ~4V

📋 Overview

This plastic battery holder case holds one (1) 18650 lithium-ion battery, providing approximately 3.7V–4.2V of output depending on the battery's charge state. It includes approximately 6-inch color-coded wire leads (red for positive, black for negative) for easy soldering or direct connection to your circuit. A simple, reliable way to add rechargeable lithium-ion battery power to your electronics projects, prototypes, or DIY builds.

💡 Tip: Use only 18650 cells that are ~65 mm in length. Some protected 18650 cells are longer (68–70 mm) and may not fit properly.

💡 Tips

• Always observe correct polarity when inserting the battery — match the + and − markings inside the holder.
• Use only 18650 cells that are ~65 mm in length. Some protected 18650 cells are longer (68–70 mm) and may not fit properly.
• Strip and tin the wire leads before soldering for a clean, reliable connection.
• Multiple single-cell holders can be wired in series or parallel to create custom voltage or capacity packs.
• Always use a proper lithium-ion charger to charge 18650 batteries — do not overcharge or over-discharge.
• Remove the battery when the holder will not be used for an extended period.
• Consider adding a battery protection circuit (BMS) when using Li-Ion cells in your projects to prevent over-discharge and short circuits.
