19S-30A LiFePO₄ (LFP) BMS — DALY Model

Overview

The DALY 19S-30A BMS is designed to manage and protect 19-series LiFePO₄ battery packs. It supports continuous current up to 30A, providing essential cell monitoring, balancing, and safety features to maximize battery lifespan and performance.

Specifications

• Cell Configuration: 19S (19 cells in series)

• Battery Chemistry: LiFePO₄ (LFP)

• Nominal Voltage: ~60.8V (3.2V nominal per cell × 19)

• Maximum Continuous Current: 30A

• Peak Current: Typically higher for short bursts (e.g., 40A – 50A)

• Balancing: Passive balancing of individual cells

• Balance Current: Approximately 30mA to 100mA

• Protections:

  • Over-voltage

  • Under-voltage

  • Over-current

  • Short-circuit

  • Over-temperature and under-temperature

• Communication:

  • Optional Bluetooth or CAN interface (model dependent)

• Operating Temperature Range: -20°C to +60°C (typical)

Features

• Real-time individual cell voltage monitoring

• Automatic passive balancing during charging

• Safety cutoff functions to protect battery and user

• Compact and rugged DALY design for reliable operation

• Optional communication modules for remote monitoring and configuration

Applications

• Electric vehicles with 60V LiFePO₄ battery packs

• Solar energy storage systems

• Portable power stations

• DIY battery pack projects with 19S configuration

Important Notes

• Compatible only with LiFePO₄ chemistry—do not use with other battery types.

• Proper wiring of balance leads and main terminals is critical.

• Cooling or ventilation may be needed during high load or high temperature operation.

• Ensure charger and load currents do not exceed the 30A continuous rating.

• DALY BMS models often support Bluetooth app monitoring and firmware upgrades—check your specific model’s documentation.
