Introducere
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.

Componente incluse:
- 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)
Instrucțiuni de cablare:
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.

- Pregătiți pachetul de baterii: Ensure all individual cells in your LiFePo4 4S 12V battery pack are at a similar voltagnivelul e înainte de conectarea BMS-ului.
- Conectați firele de echilibrare: 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 al unui singur șir.
- Conectați cablurile principale de alimentare: Connect the main negative (B-) and positive (P+) cables from the BMS to the battery pack and the load/charger respectively.
- Activate the 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).
Conexiune la aplicația mobilă:
- 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.

Setări parametri:
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:
- Supraîncărcare voltage protectie
- Vol. supradescărcaretage protectie
- 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.
Funcții de protecție:
The DALY Smart BMS is equipped with multiple protection features to ensure the safety and longevity of your LiFePo4 battery pack:
- Protecție la supraîncărcare: Stops charging when cell voltage reaches a set limit.
- Protecție la supradescărcare: Stops discharging when cell voltage drops to a set limit.
- Protecție la supracurent: Stops charging or discharging if current exceeds programmed limits.
- Protecție la scurtcircuit: Protects against short-circuit events.
- Peste voltage Protecție: Prevents overall battery voltage from exceeding safe levels.
- Funcția de echilibru: Actively balances cell voltages to maintain pack health.
- NTC Temperature Protection: Monitors battery temperature and stops current if limits are reached.
