Compact Lithium Battery Charging and Protection Board with 5V Input and 1000mA Charging Current

This integrated charging and protection board combines essential functions for single-cell lithium batteries in a space-efficient design measuring just 2.6 cm by 1.7 cm. With its 5V input voltage compatibility, it connects easily to standard USB power sources or regulated power supplies, eliminating the need for complex voltage conversion circuits. The board's blue colour provides visual identification while its integrated protection circuits offer multiple safety features to preserve battery lifespan and prevent dangerous conditions during charging and discharge cycles.

Features and Construction

The board incorporates both charging management and battery protection circuits on a single printed circuit board, reducing component count and simplifying integration into electronic projects. Its compact dimensions allow installation in space-constrained applications while providing comprehensive lithium battery management.

Material and Build

Constructed as a printed circuit board with surface-mounted electronic components, this integrated solution combines charging circuitry with protection functions. The blue solder mask provides both visual identification and standard PCB protection, with all necessary components factory-installed and configured according to the specified charging and protection parameters for immediate use without additional configuration.

Size and Practical Fit

Measuring 2.6 cm by 1.7 cm, the board offers a compact footprint suitable for integration into various electronic devices and DIY projects where space efficiency matters. This dimensional specification allows designers to allocate minimal board area for battery management functions while still obtaining complete charging and protection capabilities in a single integrated unit.

Uses and Placement

This integrated board serves applications requiring reliable lithium battery charging and protection without dedicating significant design resources to these functions. Its complete functionality in a compact form makes it suitable for both prototype development and production applications where component count and assembly time need minimization.

Event or Professional Use

For event equipment, portable instruments, or professional devices using lithium batteries, this board provides ready-made battery management that meets standard charging and protection requirements. The 5V input compatibility simplifies power system design while the integrated protection circuits offer safety compliance without additional component selection and testing, reducing development time for products requiring battery-powered operation.

Everyday Home Use

In DIY electronics projects, hobbyist creations, or home-built devices incorporating rechargeable lithium batteries, this board eliminates the complexity of designing separate charging and protection circuits. Its factory-configured parameters ensure proper battery handling according to the specified voltage and current limits, providing a reliable solution for makers who want to focus on their core project functionality rather than battery management subsystems.

Benefits and Buying Value

This integrated approach to lithium battery management offers practical advantages for both development efficiency and end-product reliability. By combining multiple functions in one compact unit, it reduces design complexity while maintaining the necessary safety features for proper lithium battery handling.

Reuse and Low Maintenance

The board's complete functionality reduces the need for separate charging circuits and protection modules in multiple projects, offering consistent performance across applications. With its specified protection parameters factory-set, it requires no calibration or adjustment, providing reliable operation that maintains battery health through proper charging termination at 4.2V ±1% and protection against over-discharge at 2.5V.

Why Choose This Product

This integrated board offers a practical solution for adding lithium battery charging and protection to electronic projects without designing these circuits from individual components. The 1000mA maximum charging current supports reasonable charging times while the 3A overcurrent protection provides safety margin for typical applications. With all parameters specified and the compact 2.6 x 1.7 cm dimensions, it delivers a complete battery management subsystem in minimal space with known performance characteristics.
