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.

Зымдарды орнотуу боюнча көрсөтмөлөр:
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.

- Prepare the Battery Pack: Ensure all individual cells in your LiFePo4 4S 12V battery pack are at a similar voltage level before connecting the BMS.
- Connect Balance Wires: 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 of a single string.
- Негизги электр кабелдерин туташтыруу: 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.
Маанилүү: 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).
Мобилдик колдонмо туташуусу:

Параметр орнотуулары:
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:
- Ашыкча заряддоо тtagд коргоо
- Ашыкча разряд тtagд коргоо
- Over-current protection (charge and discharge)
- Temperature protection (high and low for charge/discharge)
- Тtage balancing settings
Always modify parameters under the guidance of the battery manufacturer or a qualified expert to prevent damage to the battery or BMS.
Коргоо функциялары:
The DALY Smart BMS is equipped with multiple protection features to ensure the safety and longevity of your LiFePo4 battery pack:
- Ашыкча заряддан коргоо: Stops charging when cell voltage reaches a set limit.
- Ашыкча разряддан коргоо: Stops discharging when cell voltage drops to a set limit.
- Ашыкча ток коргоо: Stops charging or discharging if current exceeds programmed limits.
- Кыска туташуулардан коргоо: Protects against short-circuit events.
- Көлөмүtage Коргоо: Prevents overall battery voltage from exceeding safe levels.
- Balance Function: Actively balances cell voltages to maintain pack health.
- NTC Temperature Protection: Monitors battery temperature and stops current if limits are reached.
