4S-60A LiFePO₄ (LFP) BMS — DALY Model

Overview

The DALY 4S-60A BMS is designed for 4-series LiFePO₄ battery packs, supporting continuous currents up to 60A. It provides essential protection and balancing features to ensure safe operation and maximize battery lifespan.

Specifications

• Cell Configuration: 4S (4 cells in series)

• Battery Chemistry: LiFePO₄ (LFP)

• Nominal Voltage: ~12.8V (3.2V nominal per cell × 4)

• Maximum Continuous Current: 60A

• Peak Current: Usually higher for short bursts (e.g., 80A – 100A, model dependent)

• Balancing: Passive balancing of individual cells

• Balance Current: Typically around 30mA to 100mA

• Protections:

  • Over-voltage protection

  • Under-voltage protection

  • Over-current protection

  • Short-circuit protection

  • Over-temperature and under-temperature protection

• Communication:

  • Some DALY BMS models include optional Bluetooth or CAN interfaces (model dependent)

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

Features

• Real-time monitoring of individual cell voltages

• Automatic passive cell balancing

• Safety cutoffs to prevent damage or hazards

• Robust, compact design suitable for various applications

• Optional communication modules for monitoring and control (check model specs)

Applications

• Electric bikes and scooters

• Solar battery storage systems

• Portable power banks and stations

• DIY LiFePO₄ battery pack projects

Important Notes

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

• Ensure proper wiring and balance lead connections for safety and function.

• Cooling or ventilation may be needed under continuous high load.

• Verify your charger and load do not exceed the 60A continuous rating.

• DALY BMS units sometimes support firmware upgrades and app monitoring—confirm for your model.
