16S-30A LiFePO₄ (LFP) BMS — DALY Model

Overview

The DALY 16S-30A BMS is designed for 16-series LiFePO₄ battery packs, supporting continuous current up to 30A. It provides vital protection, cell balancing, and monitoring functions to ensure battery safety and longevity.

Specifications

• Cell Configuration: 16S (16 cells in series)

• Battery Chemistry: LiFePO₄ (LFP)

• Nominal Voltage: ~51.2V (3.2V nominal per cell × 16)

• Maximum Continuous Current: 30A

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

• Balancing: Passive cell 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 available on some models

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

Features

• Real-time monitoring of individual cell voltages

• Automatic passive balancing during charging

• Safety cutoff features for battery and user protection

• Compact and robust design from DALY for reliable performance

• Optional communication modules for remote monitoring and control

Applications

• Electric bikes and scooters with 51.2V LiFePO₄ battery packs

• Solar energy storage and backup systems

• Portable power banks and stations

• DIY LiFePO₄ battery pack projects requiring 16S configuration

Important Notes

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

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

• Cooling or ventilation may be needed during continuous high current operation.

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

• DALY BMS models may support firmware upgrades and Bluetooth app monitoring—refer to your specific model documentation.
