Overview
The DALY 10S-30A BMS is designed for 10-cell LiFePO₄ battery packs in series. It supports continuous current up to 30A and offers protection, passive balancing, and optional communication features for safe and reliable operation.

Specifications

• Cell Configuration: 10S (10 cells in series)

• Battery Chemistry: LiFePO₄ (LFP)

• Nominal Voltage: 32V (3.2V × 10)

• Maximum Continuous Current: 30A

• Peak Current: Usually up to 40A (short bursts)

• Balancing Type: Passive balancing

• Balance Current: Approximately 30mA to 80mA

• Protection Features:

  • Over-voltage protection

  • Under-voltage protection

  • Over-current protection

  • Short-circuit protection

  • Over-temperature protection

  • Under-temperature protection

• Communication (model dependent):

  • Bluetooth

  • UART

  • CAN

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

Features

• Real-time monitoring of each cell voltage

• Automatic passive cell balancing during charging

• Comprehensive safety protections for charge and discharge

• Optional Bluetooth monitoring via DALY app (model specific)

• Compact design suitable for medium power LiFePO₄ packs

Applications

• 32V LiFePO₄ battery systems

• Electric bikes, scooters, and light electric vehicles

• Solar and backup energy storage

• Portable power supplies

• DIY 10S battery pack projects

Important Notes

• For LiFePO₄ cells only (3.2V nominal per cell)

• Correct wiring of balance leads and main terminals is essential

• Charger and load current should stay within 30A continuous rating

• Bluetooth and smart features depend on BMS model

• Cooling may be needed under continuous high load
