15S-50A LiFePO₄ (LFP) BMS — DALY Model

Overview

The DALY 15S-50A BMS is designed for 15-series LiFePO₄ battery packs, supporting continuous current up to 50A. It provides essential protections and cell balancing to keep your battery pack safe, efficient, and long-lasting.

Specifications

• Cell Configuration: 15S (15 cells in series)

• Battery Chemistry: LiFePO₄ (LFP)

• Nominal Voltage: ~48V (3.2V nominal per cell × 15)

• Maximum Continuous Current: 50A

• Peak Current: Higher for short bursts (typically 70A or more)

• Balancing: Passive balancing

• Balance Current: Approximately 30mA to 100mA

• Protections:

  • Over-voltage protection

  • Under-voltage protection

  • Over-current protection

  • Short-circuit protection

  • Temperature protection (over and under)

• Communication:

  • Optional Bluetooth or CAN interfaces (model dependent)

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

Features

• Real-time monitoring of individual cell voltages

• Automatic passive cell balancing

• Safety cutoffs to prevent battery damage or hazards

• Compact, robust DALY design suitable for mid-high power applications

• Optional communication modules for remote monitoring and firmware updates

Applications

• 48V electric vehicles and e-bikes

• Solar energy storage and backup systems

• Portable power stations

• DIY LiFePO₄ battery pack projects

Important Notes

• Use only with LiFePO₄ battery chemistry.

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

• Cooling or ventilation may be required at high continuous current.

• Verify compatibility with your charger and load specifications relative to the 50A continuous rating.

• DALY BMS units may support Bluetooth app monitoring and firmware upgrades—refer to your model’s documentation.
