Rechargeable 502018 LIPO Battery Cell 3.7V 600mAh Wire Solder (Actual Capacity 160mAh)

Product Description

The 502018 3.7V Rechargeable LiPo Battery is a compact lithium-polymer battery cell designed to provide portable DC power for small electronic devices, embedded systems, and DIY electronics projects. Its lightweight pouch-cell construction makes it suitable for applications where limited installation space and low battery weight are important.

The battery operates at a nominal voltage of 3.7V DC and features pre-attached solder wires for convenient integration into electronic circuits. These wires allow the battery to be connected to compatible charging modules, battery-management circuits, and electronic devices without requiring a separate battery holder.

Although the product title advertises a capacity of 600mAh, the actual stated capacity is 160mAh. This is the capacity that should be used when estimating battery runtime, selecting a charging current, and designing the power system. The advertised 600mAh value should not be treated as the usable capacity.

The 502018 model designation commonly indicates approximate cell dimensions of 5 × 20 × 18mm (thickness × width × length). These compact dimensions make the battery suitable for small enclosures and space-constrained electronic assemblies. Actual dimensions should be checked before designing a battery compartment or mounting arrangement.

This rechargeable LiPo cell can be used in portable sensors, small wireless devices, microcontroller-based systems, compact IoT products, and other low-power electronics. Its solder-wire connection and compact format make it convenient for prototypes and custom-built electronic devices.

For safe operation, the battery must be charged using a dedicated single-cell lithium-polymer charging circuit with the correct charging voltage and current. A standard 3.7V LiPo cell typically requires a maximum charging voltage of 4.2V. It must not be connected directly to a 5V power supply, and correct polarity must be maintained during installation.
