Description
Product Specifications
Key Features
-
Rugged 3-Cell Configuration: Designed to house three standard 18650 cylindrical lithium-ion cells securely in a space-efficient, side-by-side array.
-
Pre-Stripped Wire Leads: Comes with flexible, color-coded red (positive) and black (negative) wire leads pre-soldered and stripped at the ends, ensuring fast and seamless integration into custom circuits.
-
Reliable Series Connection: Utilizes high-tension steel coil springs to bridge all three cells in a series configuration, ensuring a stable, low-resistance electrical connection.
-
Impact-Resistant Chassis: Molded from rigid, durable black ABS plastic to provide structural protection for the cells against mechanical shock, vibration, and accidental impact.
-
Versatile Mounting Design: Built with integrated through-hole mounting points in the base, allowing for clean, fixed installation onto prototyping boards, robotics chassis, or industrial enclosures.

Primary Applications
Ideally optimized for powering portable electronics, robotics, and custom power bank assemblies:
-
Robotics & RC Platforms: Supplies a robust 11.1V power rail suitable for driving DC motor controllers, robotic servo arms, and custom motorized chassis.
-
DIY Prototyping & Arduino: Acts as a solid, semi-permanent power source for breadboard projects, IoT sensor nodes, and micro-controller rigs requiring higher voltage thresholds.
-
Portable LED Lighting: Perfect for building custom high-output LED arrays, portable shop lights, or off-grid emergency illumination systems.
-
Field Instrumentation: Ideal for field-use electronic test equipment, remote measurement sensors, and specialized diagnostic benches that require a portable battery pack.
Handling and Safety
⚠️ Usage Note: This holder is configured for a series connection. Ensure that all three cells are of the same brand, capacity, and charge level before insertion. Use only with high-quality cells; if utilizing unprotected cells, ensure your circuit has an appropriate Battery Management System (BMS) to protect against over-discharge or short-circuit conditions.
