Skip to product information
This battery protection board is designed for 4-string lithium iron phosphate (LiFePO4) battery systems, providing essential safeguards like overcharge, over-discharge, and short-circuit protection. Available in continuous current ratings from 15A to 500A, it includes models with built-in cell balancing to maintain voltage equality across cells, which helps prevent capacity fade and extends overall battery lifespan. Optional integrated cooling fans on higher-current variants (80A to 500A) manage heat dissipation during operation, ensuring reliable performance under load.
The board offers a range of configurations to suit different applications, from low-power setups to high-current demands. Key aspects include the same-port design for simplified wiring and the inclusion of cell balancing, which addresses common issues in multi-cell battery packs.
This protection board is suited for various scenarios where lithium iron phosphate batteries are used, from renewable energy systems to electric vehicles. Its configurations allow tailoring to specific power needs and environmental conditions.

Features and Technical Specifications
Current Ratings and Model Options
Models are categorised by their continuous current capacity, starting at 12V15A and increasing through increments like 20A, 30A, 40A, 50A, 60A, 80A, 100A, 120A, 150A, 200A, 250A, 300A, 400A, and up to 500A. Each variant is available with cell balancing, and those from 80A to 500A also come in fan-cooled versions, such as 12V80A with fan or 12V500A with fan, to handle higher thermal loads.Cell Balancing and Protection Functions
The built-in balancing function works by monitoring and adjusting the voltage of each cell in the 4-string setup, typically keeping them within a narrow range (e.g., ±0.05V). This prevents individual cells from overcharging or over-discharging, which can lead to reduced capacity or failure. Protection features include voltage cut-offs for overcharge (around 3.65V per cell) and over-discharge (around 2.5V per cell), along with current limiting based on the rated amperage.Construction and Cooling Design
Constructed on a printed circuit board with electronic components like MOSFETs for switching and a microcontroller for logic control, the board uses copper traces sized for the current rating. Fan-cooled models incorporate an aluminium heat sink and a DC fan to actively dissipate heat, which is crucial for maintaining efficiency and preventing thermal shutdown in high-amperage applications, such as those drawing 100A or more.Applications and Use Cases
Professional and Industrial Use
In solar power storage systems, the board can manage 12V battery banks with currents up to 500A, ensuring safe operation during peak charging or discharging. For electric vehicles or marine applications, fan-cooled models like the 12V200A with fan provide reliable thermal management under continuous high loads, reducing the risk of overheating in confined spaces.Everyday Consumer Use
For home energy storage or caravan setups, lower-current models such as 12V30A with balancing offer protection without complex cooling, giving users confidence in battery safety. The same-port design simplifies installation, making it accessible for DIY enthusiasts who value straightforward wiring and the assurance of balanced cells for consistent power delivery.Versatility Across Power Ranges
Benefits and Value Proposition Investing in this protection board brings measurable advantages in battery management and longevity, supported by its specific features and configurations.Long-Term Value and Cost Savings
By preventing overcharge and over-discharge, the board can extend the lifespan of lithium iron phosphate batteries, which might otherwise degrade faster without protection. Cell balancing further enhances this by ensuring all cells age uniformly, potentially delaying the need for battery replacement and offering cost savings over time compared to unprotected setups.User Satisfaction and Reliability
Users gain peace of mind from the board's protection mechanisms, such as the precise voltage cut-offs that prevent damage during extreme conditions. In fan-cooled models, the active cooling provides confidence during sustained high-current use, reducing worries about thermal failure and ensuring consistent performance in demanding applications like powering tools or vehicles.Reason to Purchase
Choose this board for its specific current ratings and balancing features, which cater to exact power requirements and improve battery efficiency. Whether you need a 12V50A model for a small system or a 12V300A with fan for industrial use, it offers tailored solutions with measurable benefits in safety and longevity, making it a practical addition to any lithium iron phosphate battery setup.
