Key Advantages of This 4S BMS:
Enhanced Thermal Management with Aluminum Substrate: The integrated aluminum substrate ensures superior heat dissipation, critical for maintaining stable performance during high-current operation (up to 200A continuous charge/discharge). This thermal efficiency extends the BMS’s lifespan and reliability, even in harsh environments—ideal for outdoor or industrial applications.
Comprehensive Protection Suite: Equipped with hardware-level safeguards, including overvoltage, undervoltage, overcurrent, high/low temperature, and short-circuit protection, this 4S BMS acts as a robust shield for your LiFePO4 battery packs, preventing damage and ensuring operational safety.
Intelligent Cell Balancing: Supports customizable balancing parameters (starting voltage, voltage difference) with options for charge balancing or static balancing. This feature ensures uniform cell voltage across the 4-series pack, maximizing capacity utilization and extending battery cycle life.
Multi-Communication Capabilities: Standard support for Bluetooth, RS485, and CAN communication enables real-time monitoring and data logging. Optional UART communication further enhances integration flexibility for smart systems.
Low Power Consumption: Automatically enters sleep mode during inactivity, reducing power draw to ≤300µA—perfect for energy-sensitive applications like street lights or backup storage.
Flexible Scalability: Supports series and parallel connection of battery packs, allowing easy expansion to meet varying power demands.
Ideal Applications for YKN-BMS4S:
This 4S BMS is tailored for:
Small energy storage batteries (residential or commercial mini-ESS).
LED street lights and outdoor lighting systems.
12V lead-acid replacement lithium batteries (for mobility scooters, UPS, etc.).
Portable power stations and backup power units.
Low-voltage industrial equipment requiring stable battery management.
