Please read this manual thoroughly before use.
2. د خوندیتوب معلومات
د خوندیتوب مهم خبرداری:
- This protection board is مناسب نه دی for lithium iron phosphate batteries, hernia lamps, hand drill battery packs, electric fish battery packs, electric bicycle battery packs, 775 (4A) motors, or 1W fish eye LED lights.
- Ensure that the battery pack's voltage, capacity, and internal resistance are well-matched for optimal performance and safety.
- د بیټرۍ حجمtage should be approximately 3.7V (rated voltage) for proper operation.
- If the battery pack does not output voltage after assembly, it can be charged with an 8.4V charger to activate the protection board.
- Always observe correct polarity when connecting the board to batteries and charging/discharging circuits. Incorrect wiring can damage the board and batteries.
- Handle with care to avoid electrostatic discharge, which can damage electronic components.

6. عملیاتي لارښوونې
Once the BMS board is correctly wired to your 2S battery pack, it will automatically manage the charging and discharging processes, providing protection against common battery issues.
چارج کول:
- Connect an appropriate 8.4V-9V charger to the P+ and P- terminals.
- The BMS will monitor the individual cell voltages and terminate charging if any cell reaches the overcharge voltage رینج (4.25-4.35V).
- The balance function will work to equalize the voltage between the two cells during charging.
خارجول:
- Connect your load to the P+ and P- terminals.
- The BMS will cut off discharge if any cell reaches the over-discharge voltage range (2.5-3.0V) to prevent battery damage.
- The maximum continuous discharge current is 10A, with an instantaneous peak of 20A. Exceeding these limits may trigger protection.

7. ستونزه حل کول
- د تولید حجم نشتهtage after Assembly:
If the battery pack does not show output voltage after initial assembly, connect an 8.4V charger to the P+ and P- terminals. This will typically activate the protection board and restore output.
- Short Circuit Protection Triggered:
If a short circuit occurs, the board will cut off output. To recover, remove the short circuit and then connect a charger to the P+ and P- terminals to reset the protection.
- Battery Pack Not Charging/Discharging Properly:
Verify all wiring connections, especially B+, B-, BM, P+, and P-. Ensure that the battery cells are healthy and their voltage, capacity, and internal resistance are matched. Check if the charging voltage is within the specified 8.4V-9V range.
- Overcharge/Over-discharge Protection Constantly Triggering:
This could indicate an issue with the battery cells themselves (e.g., unbalanced cells, degraded capacity) or an incorrect charging/discharging setup. Check individual cell voltages and ensure they are within safe operating limits.
8. ساتنه
- Keep the BMS board clean and free from dust and moisture.
- Avoid exposing the board to extreme temperatures outside its operating and storage ranges.
- Regularly inspect wiring for any signs of damage or loose connections.
