The JKBMS B2A8S30P is a high-performance, smart battery management system designed to provide reliable protection and advanced features for lithium-ion battery packs configured from 4S to 8S. Ideal for applications such as electric vehicles, energy storage systems, and solar power setups, this Battery Management System ensures optimal safety, longevity, and performance of your battery pack.

Key Features:

• Battery String Support: Compatible with 3S to 8S lithium-ion battery configurations.
• 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.
• Standby Power: Consumes less than 2mA when in standby mode.
• Operational & Storage Temperature: Functions reliably from -40°C to 85°C during operation, and from -40°C to 95°C when stored.

This advanced BMS combines active balancing, robust protection features, and smart communication capabilities, making it an excellent choice for ensuring safety, efficiency, and longevity of your lithium battery systems.
