2. 主な特徴

The Electronic Spices 4S 20A BMS Module offers the following protective and management features:

• 充電Voltage: DC14.8V
• 消費電流: 20A
• 過充電検出電圧tage: 3.90V ± 0.25V per cell
• オーバーチャージリリースVol.tage: 3.80V ± 0.05V per cell
• 過放電検出電圧tage範囲： 2.0V ± 0.08V per cell
• 短絡保護: Automatically disconnects output in case of a short circuit.
• 過電流保護： 過剰な電流による損傷を防ぎます。
• セルバランス: Helps maintain equal voltage across all cells in the pack for optimal performance.

3. セットアップと配線

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. B1を接続する to the positive terminal of the first cell and the negative terminal of the second cell.
3. B2を接続する to the positive terminal of the second cell and the negative terminal of the third cell.
4. B3を接続する 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.

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

4. 操作手順

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.

• 充電： 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.
• 放電中: Connect your load to the P+ and P- terminals. The BMS will monitor the discharge, preventing over-discharge and overcurrent.
• 保護の有効化: If any protection threshold (overcharge, over-discharge, overcurrent, short circuit) is met, the BMS will temporarily cut off the output to protect the batteries.
• 回復： 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. メンテナンス

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

• 定期点検: すべての配線接続に緩みや腐食がないか定期的に確認してください。
• 清潔さ: モジュールをほこり、汚れ、湿気から守ってください。清掃には柔らかく乾いた布を使用してください。
• 環境条件: Operate the module within its specified temperature and humidity ranges. Avoid extreme temperatures.
• バッテリーの状態: Ensure the individual 18650 cells used with the BMS are in good condition and are of similar capacity and internal resistance for best performance.

6。 トラブルシューティング

If you encounter issues with your BMS module, consider the following troubleshooting steps:
