High - Performance Lithium Battery Protection Circuit Board with Balance Charging Capability (100A) (5pcs 4S 12V 100A)

🛡️ Product Name: 3S/4S/5S Lithium Battery Protection Circuit Board (Model: QS-B305ABL-50A)

🧩 Product Overview: The QS-B305ABL-50A is a sophisticated lithium battery protection circuit board designed specifically for a range of lithium battery chemistries, including lithium phosphate, ternary lithium (LMO), lithium cobalt oxide, and lithium manganese oxide batteries. This board is engineered to enhance the safety and performance of battery systems by providing comprehensive protection features. The design includes configurations for three, four, and five series connections, allowing for flexible application across various battery types. It integrates a robust protection circuit, utilizing high-quality integrated circuits (ICs) and advanced disconnection protection mechanisms to prevent overcurrent and short-circuits.

🧩 Key Functional Features:

• This versatile protection board allows users to customize their setup based on 3, 4, or 5 series connections, simplifying the transition based on individual requirements. The default configuration is based on the selection made during purchase, and users can effortlessly refer to the provided wiring diagrams for installation.
• The QS-B305ABL-50A employs 15 premium ultra-low internal resistance MOSFETs, comprising 8 for discharging and 7 for charging, ensuring high-performance operation. Capable of supporting a discharge current of up to 60A and charge current of 60A in the same port mode, the board can handle even greater capacities with separate port configurations, reaching 80A for discharging and 60A for charging. The ultra-low internal resistance—around 3 milliohm per MOSFET—guarantees efficient and stable performance, minimizing energy loss and heat generation during operation.
• Designed with effective cell balancing capabilities, the board maintains hardware balance across cells, managing appropriate balance currents to ensure optimal performance without compromising the battery pack's functionality or lifespan.

💎 This protection board is an ideal choice for individuals and businesses looking to enhance their lithium battery systems with a reliable and efficient management solution.
