- Continuous Current: Supports up to 300A to accommodate high-power applications.
- Self-powered Operation: The system operates using power supplied by the battery pack itself.
- Cell Voltage Detection: Measures single-cell voltages in the range of 0-5V with an accuracy error less than 10mV across the full operating span, typically within 5mV.
- Active Balance Technology: Implements active balancing with a balance current of 2000mA, ensuring cells remain balanced during full state operation.
- Short Circuit Protection: Equipped with support for short circuit prevention.
- Bluetooth Connectivity: Built-in Bluetooth enables easy monitoring via Android and iOS devices.
- Temperature Monitoring: Detects temperatures from -40°C to 125°C, providing vital safety data.
- Total Voltage Detection: Monitors the total voltage within the range of 0-100V with a measurement accuracy of less than 0.5% FS.
- Current Sense Shunt: Supports current measurement from -150A to 300A with less than 0.5% error.
- State of Charge (SoC) Estimation: Provides accurate capacity estimation with an error margin under 8%.
- Cycle Count & Capacity Tracking: Records cumulative charge/discharge capability, giving insights into battery lifespan.
- Power Consumption: Operates with less than 5mA (without communication) and 15mA when using 485/CAN communication.
