• Балансирање на клетките: Helps maintain equal voltage across all cells in the pack for optimal performance.

3. Поставување и поврзување

Proper wiring is crucial for the safe and correct operation of the BMS module. Refer to the diagram below for connection details. Always ensure power is disconnected before making any connections.

1. Connect B- to the negative terminal of the first battery cell (B1-).
2. Поврзете го B1 to the positive terminal of the first cell and the negative terminal of the second cell.
3. Поврзете го B2 to the positive terminal of the second cell and the negative terminal of the third cell.
4. Поврзете го B3 to the positive terminal of the third cell and the negative terminal of the fourth cell.
5. Connect B+ to the positive terminal of the fourth battery cell (B4+).
6. Connect P- to the negative terminal of your load/charger.
7. Connect P+ to the positive terminal of your load/charger.

Забелешка: Ensure all connections are secure and insulated to prevent short circuits. Incorrect wiring can damage the BMS, batteries, or connected devices.

4. Упатства за работа

Once properly wired, the BMS module will automatically manage the charging and discharging of your 4S Li-ion battery pack. It provides protection against common battery issues.

• Полнење: Connect a compatible 14.8V (or slightly higher, up to 16.8V for full charge) Li-ion charger to the P+ and P- terminals. The BMS will manage the charging process, preventing overcharge.
• Испуштање: Connect your load to the P+ and P- terminals. The BMS will monitor the discharge, preventing over-discharge and overcurrent.
• Активирање на заштита: If any protection threshold (overcharge, over-discharge, overcurrent, short circuit) is met, the BMS will temporarily cut off the output to protect the batteries.
• Обнова: Most protection states will automatically reset once the fault condition is removed (e.g., removing the short circuit, connecting a charger after over-discharge).

5. Одржување

The Electronic Spices BMS module is designed for low maintenance. However, following these guidelines can help ensure optimal performance and longevity:

• Редовна инспекција: Периодично проверувајте ги сите жичени врски за лабавост или корозија.
• Чистота: Keep the module free from dust, dirt, and moisture. Use a soft, dry cloth for cleaning.
• Еколошки услови: Operate the module within its specified temperature and humidity ranges. Avoid extreme temperatures.
• Здравје на батеријата: Ensure the individual 18650 cells used with the BMS are in good condition and are of similar capacity and internal resistance for best performance.
