Introduction
This manual provides detailed instructions for the installation, operation, and maintenance of your DALY Smart BMS (Battery Management System) for LiFePo4 4S 12V 200A battery packs. The BMS features a programmable Bluetooth module for monitoring and parameter adjustment via a mobile application. It is designed to protect lithium batteries from various conditions including over-charge, over-discharge, over-current, and temperature extremes, while also providing cell balancing.

Précautions de sécurité
- Always wear appropriate personal protective equipment (PPE) when working with batteries.
- Ensure all connections are secure and correctly polarized to prevent damage to the BMS or battery.
- Ne court-circuitez pas les bornes de la batterie.
- Avoid exposing the BMS to water or extreme temperatures beyond its operating range.
- Consult a qualified professional if you are unsure about any installation or operation steps.
Installation
Composants inclus :
- Smart BMS unit
- Balance wires
- Bluetooth module (for Mobile APP IOS & Android)
- UART cable (for PC screen)
- English version wiring manual (refer to this for detailed diagrams)
Instructions de câblage:
Follow the wiring diagram carefully. Incorrect wiring can damage the BMS and battery. It is crucial to connect the balance wires correctly to each cell in the battery pack.
Image: Detailed wiring diagram showing connections from the battery cells to the BMS, and then to the motor/load and charger. This diagram is essential for correct installation.
- Préparer le bloc-batterie : Ensure all individual cells in your LiFePo4 4S 12V battery pack are at a similar voltage level before connecting the BMS.
- Connectez les fils d'équilibrage : Connect the balance wires from the BMS to each cell of the battery pack in the correct sequence (B-, B1, B2, B3, B+). Double-check the voltage between adjacent cables using a multimeter to confirm the wiring is normal and matches the nominal voltage d'une seule chaîne.
- Raccordez les câbles d'alimentation principaux : Connect the main negative (B-) and positive (P+) cables from the BMS to the battery pack and the load/charger respectively.
- Activer le BMS : Plug in the NTC (temperature sensor) and Bluetooth module. Press the activation button on the Bluetooth module to activate the smart BMS.
Important: Disconnect balance wires and the BMS connection port before welding black and red balance wires on the battery pack. Keep the red cooling surface side uncovered and use DALY matching balance wires (regular length 450 mm / 17.72 inch).
Connexion à l'application mobile :
- Download the "Smart BMS" application from the Huawei App Store or Apple App Store.
- Open the Smart BMS APP on your mobile phone.
- Connect to the corresponding Bluetooth device number displayed in the app.
- Upon successful connection, you can view battery parameters and adjust settings.

Paramètres des paramètres:
For the first power-on, the battery capacity must be set to the actual capacity of your battery pack. The initial password for parameter settings is 123456. You can adjust various protection parameters such as:
- Surcharge voltagprotection électronique
- Vol de décharge excessivetagprotection électronique
- Over-current protection (charge and discharge)
- Temperature protection (high and low for charge/discharge)
- Voltage balancing settings
Always modify parameters under the guidance of the battery manufacturer or a qualified expert to prevent damage to the battery or BMS.
Fonctions de protection:
The DALY Smart BMS is equipped with multiple protection features to ensure the safety and longevity of your LiFePo4 battery pack:
- Protection contre les surcharges : Stops charging when cell voltage reaches a set limit.
- Protection contre les décharges excessives : Stops discharging when cell voltage drops to a set limit.
- Protection contre les surintensités : Stops charging or discharging if current exceeds programmed limits.
- Protection de court circuit: Protects against short-circuit events.
- Survoltaget Protection: Prevents overall battery voltage from exceeding safe levels.
- Fonction d'équilibrage : Actively balances cell voltages to maintain pack health.
- NTC Temperature Protection: Monitors battery temperature and stops current if limits are reached.

Entretien
- Inspection régulière : Vérifiez périodiquement le serrage de tous les branchements électriques et l'absence de signes de corrosion ou de dommages.
- Propreté: Keep the BMS unit clean and free from dust and debris. Ensure cooling surfaces are not obstructed.
- Mises à jour logicielles : Check the DALY website or app store for any available firmware or app updates to ensure optimal performance and security.
- Conditions environnementales : Operate the BMS within its specified temperature and humidity ranges to prevent premature failure.
- Surveillance de l'état de la batterie : Regularly monitor battery parameters via the app to detect any anomalies early.
