3.7V 600mAh 14500 Lithium-Ion Battery

The 14500 3.7V 600mAh Lithium-Ion Battery is a compact, rechargeable cylindrical cell designed for a wide range of electronic devices. With the same physical size as a standard AA battery, the 14500 Li-ion cell provides significantly higher voltage (3.7V vs. 1.5V for alkaline), making it ideal for high-performance, space-constrained applications.

This battery is commonly used in LED flashlights, portable electronics, DIY electronics projects, RC toys, and IoT devices. It often includes built-in protection circuitry (in protected versions) to prevent overcharge, over-discharge, and short circuits
