3. Podešavanje i ožičenje

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. Connect B1 to the positive terminal of the first cell and the negative terminal of the second cell.
3. Connect B2 to the positive terminal of the second cell and the negative terminal of the third cell.
4. Connect 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.

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

4. Uputstvo za upotrebu

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.

• Punjenje: 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.
• Pražnjenje: Connect your load to the P+ and P- terminals. The BMS will monitor the discharge, preventing over-discharge and overcurrent.
• Aktivacija zaštite: If any protection threshold (overcharge, over-discharge, overcurrent, short circuit) is met, the BMS will temporarily cut off the output to protect the batteries.
• oporavak: 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. Održavanje

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

• Redovni pregled: Povremeno provjeravajte sve spojeve ožičenja na labavost ili koroziju.
• čistoća: Keep the module free from dust, dirt, and moisture. Use a soft, dry cloth for cleaning.
• Uslovi okoline: Operate the module within its specified temperature and humidity ranges. Avoid extreme temperatures.
• Zdravlje baterije: Ensure the individual 18650 cells used with the BMS are in good condition and are of similar capacity and internal resistance for best performance.
