It accepts a standard 5V input to safely charge a single-cell lithium battery at up to 1000mA, while its integrated protection circuit guards against over-discharge and overcurrent conditions. By precisely terminating charge at 4.2V (±1%) and cutting off power if voltage falls to 2.5V, it directly tackles the issues that compromise battery lifespan and safety. This board is engineered for makers, hobbyists, and developers needing a reliable, ready-to-use solution for powering portable electronics, DIY gadgets, and small-scale embedded systems without designing complex circuitry from scratch.\n\n\u003ch2\u003eFeatures and Technical Specifications\u003c\/h2\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"Small blue lithium battery charging and protection circuit board with solder pads, measuring 2.6cm by 1.7cm.\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US14\/29\/2025-09-28\/original-image\/153334228791.webp\"\u003e\u003c\/div\u003e\nThis section details the measurable performance data and construction of the lithium battery management board. We cover the specific electrical parameters that define its operation, the compact design that enables easy integration, and the materials that ensure reliable function in your projects.\n\n\u003ch3\u003eElectrical Performance and Protection\u003c\/h3\u003e\nThe board's core functionality is defined by its specific voltage and current ratings. It requires a 5V DC input, making it compatible with ubiquitous USB power sources and wall adapters. The charging circuit delivers a maximum current of 1000mA (1A) to the connected battery, with charging automatically stopping when the battery voltage reaches the precise threshold of 4.2 volts, within a 1% tolerance. For protection, the circuit monitors the battery voltage during discharge and will disconnect the load if voltage drops to 2.5V to prevent harmful deep discharge. Furthermore, it incorporates overcurrent protection that triggers at 3A, providing a critical safety barrier against short circuits or excessive load demands.\n\n\u003ch3\u003eCompact Design and Dimensions\u003c\/h3\u003eConstruction and Board QualityPractical Applications and Use Cases\nThe integrated design of this board solves specific power management challenges across various fields. From professional prototyping to hobbyist projects, its set of features supports reliable operation in numerous scenarios where a safe, rechargeable lithium battery source is needed.\n\n\u003ch3\u003eProfessional Prototyping and Development\u003c\/h3\u003eFor engineers and product developers creating prototypes for IoT devices, portable medical sensors, or handheld test equipment, this board offers a ready-made battery management solution. It allows developers to focus on their core application circuitry without dedicating design time to the charging and protection subsystems. The 3A overcurrent protection provides a built-in safety feature during the prototyping phase, where wiring errors or faulty components could otherwise lead to battery damage or safety concerns. Its 5V input compatibility simplifies power supply design, often allowing direct connection to a development board's USB port for charging during testing.\n\n\u003ch3\u003eEveryday DIY Electronics and Hobby Projects\u003c\/h3\u003eFor the electronics hobbyist, this module brings professional-grade battery safety to the workbench. The satisfaction of building a portable Bluetooth speaker or a remote-controlled model is enhanced by the confidence that the lithium battery inside is being managed correctly. The physical experience of integrating the board is straightforward due to its clear terminals for battery, input, and output. The solid feel of the FR-4 board and the secure solder joints provide tangible reassurance of a job well done, turning a complex electrical safety requirement into a simple, plug-and-play component that just works.\n\n\u003ch3\u003eVersatility in Custom Power Solutions\u003c\/h3\u003eBeyond typical battery packs, this board's specifications enable several alternative uses. It can serve as a dedicated charging module for a bank of batteries managed in parallel. Its 2.5V cut-off can be utilised in low-power sensor nodes to guarantee a minimum operational voltage, ensuring data integrity before sleep mode is engaged. For educational purposes, it provides a clear, tangible example of voltage monitoring and protection circuitry, with test points that allow students to measure the 4.2V cut-off and 3A protection trigger in a lab setting. Its small size also makes it suitable for retrofitting into existing devices to upgrade them from disposable to rechargeable battery power safely.\n\n\u003ch2\u003eBenefits and Long-Term Value\u003c\/h2\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"Small blue lithium battery charging and protection circuit board with solder pads, measuring 2.6cm by 1.7cm.\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US14\/29\/2025-09-28\/original-image\/1759240881925.webp\"\u003e\u003c\/div\u003e\nChoosing this integrated board provides concrete advantages over sourcing and wiring separate components. The benefits extend from immediate project simplification to long-term reliability and cost savings, rooted in its specific technical specifications and integrated design.\n\n\u003ch3\u003eValue Through Integration and Reliability\u003c\/h3\u003eThe primary value proposition is the consolidation of two critical circuits—charging and protection—onto one pre-tested board. Sourcing a separate charging IC, protection IC, and all necessary passive components would incur higher individual costs and require additional PCB space. This module eliminates that complexity. The specified 4.2V ±1% charging accuracy helps maximise the usable cycles from a lithium battery, which directly translates to longer periods between battery replacements. For a small business producing a low-volume electronic product, using this reliable, off-the-shelf module can reduce engineering time, minimise warranty issues related to battery failure, and streamline the bill of materials.\n\n\u003ch3\u003eUser Satisfaction and Confidence\u003c\/h3\u003eThe user experience is fundamentally one of confidence and reduced risk. Knowing that a battery is protected by a 3A cut-off provides peace of mind, especially in projects left unattended or used by others. This confidence is directly linked to the board's technical specification: the knowledge that if a motor stalls or a wire shorts, the protection will activate within milliseconds. For a hobbyist, this means being able to experiment more freely without fear of destroying an expensive battery or causing a safety incident. The reliable operation afforded by the precise voltage thresholds allows users to focus on the creativity of their project rather than worrying about power management fundamentals.\n\n\u003ch3\u003eA Practical Choice for Your Project\u003c\/h3\u003eIf your project requires a single-cell lithium battery to be charged safely from a USB port and protected during use, this board provides a complete, measurable solution. Its 2.6cm x 1.7cm size defines how easily it will fit, its 5V input specifies what power source you need, and its 3A\/2.5V protections define the safety envelope for your design. Incorporating this module is a definitive step towards a more robust and user-friendly final product, turning a potential vulnerability into a managed and reliable subsystem. It represents a small investment in components that delivers a significant return in project safety, simplicity, and professional finish.\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"Small blue lithium battery charging and protection circuit board with solder pads, measuring 2.6cm by 1.7cm.\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US14\/29\/2025-09-28\/original-image\/34161336961108.webp\"\u003e\u003c\/div\u003e","brand":"v4asb1-mb","offers":[{"title":"Blue","offer_id":57037237420363,"sku":"CJJSCCYD00044-Blue","price":5.98,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1034\/5109\/9467\/files\/153334228791.webp?v=1776241920","url":"https:\/\/haverique.com\/products\/lithium-battery-charging-and-protection-integrated-circuit-board-in-blue-featuring-5v-input-1000ma-charging-current-and-3a-overcurrent-protection-for-safe-battery-management","provider":"HaveRique","version":"1.0","type":"link"}
