The EH-AAX4B/DC Battery Holder is a high-efficiency power solution designed for devices that require a standard DC barrel jack connection. Combining a large 4-slot capacity with an integrated On/Off switch, this unit provides a plug-and-play power source for various electronic applications.
Integrated 2.1mm DC Plug: Features a pre-wired 2.1mm x 5.5mm DC male barrel jack, making it directly compatible with most Arduino boards, CCTV cameras, and project enclosures.
Manual On/Off Slide Switch: Built-in switch allows for immediate power control, preserving battery life and adding a layer of safety to your prototypes.
6V High-Capacity Output: Wired in series to hold four AA batteries, providing a nominal 6.0V output (alkaline) or 4.8V (rechargeable NiMH).
Fully Enclosed Protection: The robust snap-lock cover protects the internal cells from environmental dust and prevents batteries from falling out during movement.
Impact-Resistant ABS: Manufactured from durable black ABS plastic to withstand frequent handling and portable use.
Battery Type: 4x AA
Output Voltage: Nominal 6.0V DC.
Connector: 2.1mm x 5.5mm DC Male Plug.
Switch Type: SPST Slide Switch (ON/OFF).
Housing Type: Enclosed with sliding cover.
Microcontroller Power: Perfectly suited for powering development boards like the Arduino Uno through the dedicated DC power jack.
Portable Testing Equipment: Used as a field power source for testing 6V motors, sensors, and actuators.
CCTV & Security: Provides a temporary or emergency power backup for 12V cameras that can operate on lower voltages.
DIY Robotics: Ideal for powering robotic chassis that utilize standardized DC power rails.
What is the polarity of the DC plug? The plug follows the industry-standard Center Positive configuration, which is the most common requirement for modern DC-powered electronics.
Is the cable long enough for most projects? The unit features a flexible insulated cable (approx. 150mm), providing enough slack to mount the battery box conveniently inside or outside your project enclosure.
Can I use Lithium AA batteries? Yes, but be aware that 1.5V Lithium AAs will output a full 6V, while 3.7V 14500 Lithium batteries would output 14.8V, which may damage your equipment. Always match the total voltage to your device's rating.
