Arduino Uno R3

When a single cell isn’t enough to push your motors to the limit, the 2-Cell 18650 Battery Holder steps in to deliver the heavy current you need. Engineered to securely house two high-capacity 18650 lithium-ion cells in series, this holder provides a nominal 7.4V to 8.4V output—the absolute sweet spot for powering the Arduino’s VIN pin or driving high-torque DC motors through an L298N driver.

As an IIT Bhubaneswar-incubated startup, we rigorously test our hardware to ensure it survives the dynamic environment of advanced PM Shri Labs and intense B.Tech robotics competitions. Whether you are building an all-terrain 4WD rover or a multi-servo robotic arm, this holder ensures your components never suffer from voltage drops. Complete with pre-stripped wire leads for rapid prototyping, it is the ultimate solution for untethering Uno bots and bringing your composite skill lab designs to life.
