How Does the JK-B2A24S20P Ensure Battery Safety?
The BMS integrates multiple safety protocols, including over-voltage, under-voltage, over-current, and short-circuit protection. Its 16S cell balancing system maintains voltage uniformity across LiFePO4 cells, preventing thermal runaway. The built-in power switch allows manual cutoff during emergencies, while temperature sensors monitor heat levels to avoid overheating risks.
Advanced multi-stage protection thresholds enable precise response to abnormal conditions. The over-voltage protection triggers at 3.75V±0.05V per cell, while under-voltage cutoff occurs at 2.0V±0.05V. A three-tiered temperature protection system activates cooling protocols when cell temperatures exceed 65°C and completely disconnects the load at 75°C. The short-circuit response time is under 200 microseconds, faster than most industrial circuit breakers.
| Protection Type | Activation Threshold | Response Time |
|---|---|---|
| Over-Voltage | 3.75V/cell | <2 seconds |
| Under-Voltage | 2.0V/cell | <3 seconds |
| Over-Temperature | 65°C | <5 seconds |
What Advanced Monitoring Features Does It Offer?
Via Bluetooth, users access real-time data on cell voltages, temperatures, and charge/discharge cycles through the JKBMS app. RS485 support enables integration with inverters and solar controllers for centralized energy management. The system logs historical performance data, aiding in diagnostics and optimizing battery lifespan.

The monitoring platform provides granular insights through customizable dashboards, including SOC (State of Charge) accuracy within ±3%. Users can set automated alerts for specific parameters like individual cell deviation exceeding 50mV or pack temperature gradients over 15°C. The data export function generates CSV reports detailing 30-day performance trends, particularly useful for solar array optimization.
| Parameter | Monitoring Capability | Update Frequency |
|---|---|---|
| Cell Voltage | 0-5V range | 1-second intervals |
| Pack Temperature | -40°C to +125°C | 5-second intervals |
| Current Flow | ±300A | 0.5-second sampling |
