This compact 2×2 AA battery holder connects four AA batteries in series, providing a nominal 6 V DC output (alkaline) or 4.8 V DC (rechargeable NiMH). The premium jumper header wires plug directly into a breadboard — no stripping or soldering required for prototyping.
The square 2×2 configuration keeps the holder compact. Using rechargeable NiMH batteries gives approximately 5.2 V fully charged to 4.4 V discharged, making it a convenient match for 5 V projects. With alkaline batteries (6.4 V fresh), a 1N4001 diode in series can drop the voltage to approximately 5.3 V.
Key Features
- Breadboard-Ready – Premium jumper header wires plug directly into breadboards
- Compact 2×2 Layout – Four AA batteries in a square configuration
- Series Connection – Nominal 6 V (alkaline) or 4.8 V (NiMH rechargeable)
- Solderable – Wires can also be soldered to a PCB
Voltage Output
- Alkaline – 6.4 V (fresh) to 4.0 V (depleted)
- NiMH Rechargeable – 5.2 V (fully charged) to 4.4 V (discharged)
Ideal For
- Breadboard prototyping with battery power
- 5 V Arduino and microcontroller projects (with NiMH batteries)
- Portable electronics projects
Package Contents
- 1× 2×2 AA battery holder with premium jumper header wires
Jargon buster
Plain-language definitions for the technical terms used above.
- microcontroller
- A microcontroller is a small computer on a chip that runs your program and controls connected inputs and outputs. For this product, it is the part that reads buttons and sensors, drives the display and speaker, and communicates over Bluetooth.
- PCB
- A printed circuit board is a rigid board with copper tracks that connect electronic parts without loose wires. For this kit, the PCBs also form the airplane shape, so they are both the circuit base and part of the finished model.
