Step 1: Solder the P-line to the P-pad of the protection board without connecting the charger and load;
Step 2: Connect the negative pole of the battery pack to B- of the protection board;
Step 3: Connect the positive terminal of the battery pack to B+ of the protection board;
Step 4: Connect the battery pack and battery rows to J1 of the protection board;
Step 5: Connect the battery pack and battery rows to J2 of the protection board;
Step 6: Charge and activate.
Steps to remove the protective plate:
Step 1: Disconnect all chargers\loads
Step 2: Unplug the battery pack and battery strip connector J2;
Step 3: Unplug J1 of the battery pack battery strip;
Step 4: Remove the connecting wire connecting the positive electrode of the battery pack from the B+ pad of the protective plate
Step 5: Remove the connecting wire connecting the negative electrode of the battery pack from the B- pad of the protective plate
Additional notes: Please pay attention to electrostatic protection during production operations.

2 Protection board model - (This protection board model is Fish20S008, other types of protection boards are marked, there is no limit to the number of characters in this item)
3. The number of battery strings supported by the required protection board - (this model of protection board is suitable for 20S battery packs);
4 Charging current value - 20A means the maximum support for continuous charging is 20A;
5 Discharge current value - 35A means maximum support for continuous 35A charging;
6 Balance resistance size - fill in the value directly, for example, 100R, then the balance resistance is 100 ohms;

9 Hardware version - V1.0 means the hardware version is version 1.0.
10 The model number of this protection board is: WH-Fish20S008-20S-40A-40A-100R-4-R-V1.4. Please place the order according to this model number when placing bulk orders.
1. When performing charge and discharge tests on the battery pack with the protective board installed, please do not use a battery aging cabinet to measure the voltage of each cell in the battery pack, otherwise the protective board and battery may be damaged. .
2. This protection board does not have a 0V charging function. Once the battery reaches 0V, the battery performance will be severely degraded and may even be damaged. In order not to damage the battery, the user should not charge the battery for a long time (the battery pack capacity is greater than 15AH, and the storage exceeds 1 Months) When not in use, it needs to be charged regularly to replenish the battery; when in use, it must be charged in time within 12 hours after being discharged to prevent the battery from being discharged to 0V due to self-consumption. Customers are required to have an obvious sign on the battery casing that the user regularly maintains the battery.
3. This protection board does not have reverse charging protection function. If the polarity of the charger is reversed, the protection board may be damaged.
4. This protective board shall not be used in medical products or products that may affect personal safety.
5. Our company will not be responsible for any accidents caused by the above reasons during the production, storage, transportation and use of the product.
6. This specification is a performance confirmation standard. If the performance required by this specification is met, our company will change the model or brand of some materials according to the order materials without further notification.
7. The short-circuit protection function of this management system is suitable for a variety of application scenarios, but it does not guarantee that it can be short-circuited under any conditions. When the total internal resistance of the battery pack and short-circuit loop is less than 40mΩ, the battery pack capacity exceeds the rated value by 20%, the short-circuit current exceeds 1500A, the inductance of the short-circuit loop is very large, or the total length of the short-circuited wire is very long, please test by yourself to determine whether This management system can be used.
8. When welding battery leads, there must be no wrong connection or reverse connection. If it is indeed connected incorrectly, the circuit board may be damaged and needs to be retested before it can be used.
9. During assembly, the management system should not directly contact the surface of the battery core to avoid damaging the circuit board. The assembly must be firm and reliable.
10. During use, be careful not to touch the lead tips, soldering iron, solder, etc. on the components on the circuit board, otherwise the circuit board may be damaged.
Pay attention to anti-static, moisture-proof, waterproof, etc. during use.
11. Please follow the design parameters and usage conditions during use, and the values in this specification must not be exceeded, otherwise the management system may be damaged. After assembling the battery pack and management system, if you find no voltage output or failure to charge when you power on for the first time, please check whether the wiring is correct.
