The 8xAA battery holder with DC connector is a high-capacity, portable power solution for electronics projects. It accommodates eight AA batteries in series, providing a nominal 12V output, ideal for microcontrollers, motors, LED strips, and other 12V devices. The integrated 5.5mm × 2.1mm DC barrel jack simplifies connection to standard power inputs, allowing quick setup without additional wiring.
 
Designed for convenience and reliability, the holder features a secure battery compartment with a sliding cover for easy replacement and an on/off switch for immediate control. Its robust construction ensures consistent electrical contact and durability, making it suitable for both prototypes and finished projects.
 
Perfect for robotics, portable sensor nodes, amateur radio setups, and mobile installations, this battery holder offers a flexible, reliable power source. Combine it with your Qwiic-enabled systems or standalone electronics to ensure a stable 12V supply wherever your project goes.
