DALY Smart Truck Starts BMS 150A 4S 8S UART & CAN/RS485 Protection Board with Bluetooth Module for LFP Lithium Battery Pack

Peak Overcurrent: Up to 2000A, ensuring powerful and reliable truck starts.This high peak current enables the BMS to handle the intense surges required for starting heavy-duty vehicles without risking damage to the battery system.  Ideal for trucks, buses, and industrial vehicles with high power demands.
One-Button Forced Start: A single button initiates a forced start, bypassing the need for traditional towing or jump-start methods. Provides a quick and reliable solution in emergency situations, reducing downtime and eliminating dependency on external assistance.  With this feature, vehicle operators can restart the engine effortlessly, even when the battery voltage is critically low.
Four Times Capacitance:  Features 4x capacitance for improved energy handling, effectively stabilizing power delivery.  Solves issues like screen flickering in central control systems and ensures compatibility with high-power truck electronics. Smooth operation of sensitive onboard systems, even under peak loads or startup conditions.
Three Heating Modes:  Integrated heating with three adjustable modes for optimal performance in cold environments.  Prevents battery performance degradation in sub-zero temperatures, ensuring reliable starts and prolonged battery life.
With powerful communication capabilities, the BMS allows users to view and configure parameters via mobile app, PC software, or IoT platforms, while its dual UART, CAN, and DO/I interfaces enable flexible integration across diverse applications.

3. BMS Wiring and Removal Instructions
Wiring the BMS:
1. Connect the B- Cable:
   - Begin by connecting the B- cable of the BMS to the total negative pole of the battery pack.

2. Cell Wiring:
   - Start from the thin black cable connected to B-.
   - The second wire connects to the positive terminal of the first battery cell.
   - Continue connecting each cell’s positive terminal in sequence.
   - Finally, insert the B+ cable into the BMS and connect it to the positive terminal of the last cell.

3. Verify the Setup:
   - After completing the wiring, check if the green indicator light is on.
   - Use the Bluetooth app or PC software to check for any fault alarms.
   - Measure the voltages at B+ and B-. They should match the voltages of P+ and P-. If the voltages match, the BMS is functioning properly. If not, recheck and rewire according to the steps above.
Removing the BMS:
1. Turn Off the Load Power:
   - Turn off the load power switch to prevent any electrical issues during disconnection.

2. Disconnect the Cables:
   - If there are two cables, start by pulling out the high-voltage cable first, followed by the low-voltage cable.
   - Then remove the P- cable from the BMS.

3. Final Removal of B- Cable:
   - Finally, disconnect the power line B- to complete the BMS removal process.
