3.7V Rechargeable Lithium-Ion Battery Cell 25mAh to 10000mAh – Li-Ion Battery for Arduino, ESP32, DIY Projects, RC Toys & Power Bank by Electrica in Pakistan

The 3.7V Rechargeable Lithium-Ion Battery Cell is a compact and lightweight rechargeable power source available in a wide range of capacities for electronics, embedded systems, DIY projects, Arduino, ESP32, RC toys, portable devices, power banks, Bluetooth projects, IoT devices, and other battery-powered applications.

These batteries are available in multiple capacity options ranging from 25mAh up to 10000mAh, allowing you to select a suitable battery according to your required runtime, physical size, and available installation space. Different capacity variants have different physical dimensions, so please check the selected variant carefully before ordering.

The battery provides a 3.7V nominal voltage and uses a rechargeable lithium-based cell construction. The pouch-style cells are particularly useful for compact electronic products where a slim and lightweight battery is preferred. Some variants may include wires, JST-style connectors, or solder tabs depending on the selected option.

The battery capacity determines the approximate amount of energy available and therefore the potential operating time of your device. Higher-capacity batteries generally provide longer runtime but may also have larger physical dimensions.

Important: Battery capacity, dimensions, connector type, wire configuration, and appearance vary between available variants. Please select the required capacity and verify its physical dimensions before placing your order.
