The 1S 18650 Lithium Battery Holder is a high-quality, single-slot enclosure designed to house a standard 3.7V 18650 Li-ion cell. At Electrapac, we recommend this holder as the essential "foundation" for portable projects, allowing you to easily add or swap power sources without soldering directly to the battery.

Product Overview

This battery case is made from impact-resistant black ABS plastic and features high-tension spring contacts. These springs ensure a secure electrical connection even in high-vibration environments, such as RC vehicles or portable hand-held devices. The holder comes with pre-tinned wire leads (Red for Positive, Black for Negative) for immediate integration into your circuit.

Key Features for Electrapac Customers

• Safe Battery Handling: Soldering directly to Lithium batteries is dangerous due to heat sensitivity. This holder provides a professional and safe alternative.

• Universal Fit: Designed to accommodate both "Flat-top" and "Button-top" 18650 cells.

• Flexible Mounting: The base includes small pre-drilled holes, allowing you to screw the holder directly onto a 3D-printed chassis or a wooden project board.

• Durable Construction: The thick-walled plastic prevents the battery from shifting or popping out during movement.

• Polarity Marked: Clear "+" and "-" markings inside the case help prevent reverse-polarity errors during battery insertion.

Installation & Usage Tips

To get the most out of your Electrapac battery holder:

1. Series vs. Parallel: To create a 7.4V (2S) pack, you can wire two of these 1-slot holders in series. To increase capacity (1S2P), wire them in parallel.

2. Secure the Wires: Use a small dab of hot glue or a cable tie at the wire exit point to provide strain relief if your project involves frequent movement.

3. Protection Circuits: Because 18650 cells are powerful, we recommend pairing this holder with a BMS (Battery Management System) or a TP4056 charging module to prevent over-discharging.

Primary Applications

• Arduino & ESP32 Power: Providing long-lasting mobile power for IoT sensors and microcontrollers.

• Portable LED Torches: Building or repairing high-intensity flashlights.

• RC Toys & Robotics: Powering small motors and servos in DIY robots.

• Emergency Lighting: Creating backup light sources that can be easily recharged.

• Power Bank Modules: Connecting to a USB 5V boost converter for a DIY phone charger.
