Designed for hobbyists, makers, and electronic project developers, it eliminates the need for separate charging and protection circuits by integrating both into one compact unit. Simply connect a standard 5V USB power source, and the board handles the controlled charging process up to a 1000mA current while actively monitoring for hazardous conditions like over-discharge and excessive current draw from the load. Its ready-to-use design saves time on circuit design and component sourcing, offering a reliable foundation for powering portable devices, prototypes, or custom electronics.\u003c\/p\u003e\n\u003ch2\u003eFeatures and Construction\u003c\/h2\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"Blue lithium battery charging and protection circuit board measuring 2.6 by 1.7 centimetres\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US14\/29\/2025-09-28\/original-image\/153334228791.webp\"\u003e\u003c\/div\u003e\n\u003cp\u003eThe board's primary value lies in its integration of multiple critical battery management functions onto a single, small printed circuit board. This consolidation simplifies wiring and assembly in final products. The construction is focused on providing these specified electrical characteristics within a minimal physical footprint.\u003c\/p\u003e\n\u003ch3\u003eMaterial and Build\u003c\/h3\u003e\n\u003cp\u003eThe module is built on a standard printed circuit board (PCB) which hosts all the necessary integrated circuits, resistors, capacitors, and connectors. The PCB serves as both the structural base and the electrical pathway connecting the components to realise the charging and protection algorithm. The board is supplied in a blue colour, which is a standard PCB solder mask option and aids in visual identification.\u003c\/p\u003e\n\u003ch3\u003eSize and Practical Fit\u003c\/h3\u003e\n\u003cp\u003eWith dimensions of just 26mm by 17mm, this board is designed for space-conscious applications. Its compact size allows it to be embedded into small enclosures or tucked into tight spaces within a larger assembly, such as inside a custom flashlight, a portable speaker, or a handheld gaming device. The small footprint is a key differentiator for projects where internal space is at a premium.\u003c\/p\u003e\n\u003ch2\u003eUses and Placement\u003c\/h2\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"Blue lithium battery charging and protection circuit board measuring 2.6 by 1.7 centimetres\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US14\/29\/2025-09-28\/original-image\/1759240881925.webp\"\u003e\u003c\/div\u003e\n\u003cp\u003eThis module is versatile, serving as the power management core for a wide range of battery-operated projects.
