Description
Product Specifications
Key Features
-
Individual Cell Security: Designed to securely house a single 18650 cylindrical lithium-ion cell, providing a stable, organized power source for compact electronic projects.
-
Pre-Stripped Wire Leads: Features flexible, color-coded red (positive) and black (negative) wire leads pre-soldered and stripped at the ends, allowing for instant and reliable connections to your circuit or breadboard.
-
Robust Retention Design: Built with high-tension nickel-plated steel coil springs that exert firm pressure on the cell, ensuring a continuous, low-resistance electrical contact even under movement.
-
Impact-Resistant ABS Body: Molded from durable, high-impact black ABS plastic, providing essential structural protection against mechanical shock, stress, and accidental damage to the cell.
-
Versatile Mounting Hardware: Integrated with base countersink through-holes, facilitating clean, permanent mounting onto custom robotic chassis, electronics housings, or project prototypes using standard hardware.

Primary Applications
Ideally optimized for single-cell power requirements in portable electronic builds, DIY prototypes, and sensor networks:
-
Micro-Prototyping: Provides a reliable power base for Arduino, ESP32, or Raspberry Pi Pico projects that operate on a 3.7V – 4.2V lithium-ion supply.
-
Portable Sensors: Perfect for powering remote IoT wireless sensors, environmental data loggers, or low-power telemetry nodes in off-grid setups.
-
Compact LED Drivers: Supplies a dedicated, high-capacity power source for standalone LED indicator arrays, portable flashlights, or small customized beacon modules.
-
Educational Robotics: Serves as a modular power brick for small-scale educational robotic kits, allowing for easy battery swaps during long testing sessions.
Understanding Battery Orientation
When integrating this holder into a design, it is essential to ensure the battery is oriented correctly. The positive terminal (usually the end with the slightly raised nub or flat top) must align with the corresponding positive terminal marker on the holder. Incorrect installation can result in a short circuit if your device does not have reverse-polarity protection.
Is there a specific project you are planning to use these 18650 holders for, and would you like assistance with calculating power requirements?
