20S 60V 50A Lifepo4 73v Daly BMS

Daly BMS (Battery Management System) for a LiFePO4 (Lithium Iron Phosphate) battery pack with specific specifications.

The information you’ve provided includes the following specifications:

  1. Battery Chemistry: LiFePO4 (Lithium Iron Phosphate)
  2. Configuration: 20S (20 series-connected cells)
  3. Voltage: 60V (20 cells * 3.2V per cell)
  4. Discharge Current: 50A
  5. Charge Current: 25A

The Daly BMS you mentioned seems to be designed for a 20S LiFePO4 battery pack, providing protection and monitoring for the cells within the pack. The common port on a BMS is typically used for balancing and monitoring the state of charge and health of the battery pack. The discharge current of 50A means the BMS can handle up to a 50A load on the battery, and the charge current of 25A means it can safely charge the battery at up to 25A.

Remember to ensure that the BMS you choose is compatible with your specific LiFePO4 cells and that it’s installed correctly to provide the necessary protection and management for your battery pack. Always follow the manufacturer’s guidelines and recommendations for safety and proper operation

A Daly BMS (Battery Management System) commonly used for LiFePO4 (Lithium Iron Phosphate) battery packs, especially for electric vehicles, typically has various ports and features. The specific port you are referring to as the “common port” might vary depending on the specific model and version of the Daly BMS. However, I can provide some general information about a common port in a Daly BMS for a 20S (20-series) 50A LiFePO4 battery setup.

  1. Common Port (COM): The common port, often labeled as “COM,” is a connection point that typically serves as a reference or ground point for the battery management system. It is used for monitoring and balancing the individual cells within the LiFePO4 battery pack.

Here’s what you might find when looking at a Daly BMS common port for a 20S 50A LiFePO4 setup:

  • Voltage Sensing: The common port might be connected to the negative terminal of the battery pack or to a dedicated reference point for voltage sensing. This allows the BMS to measure the voltage of each cell in the battery pack relative to the common reference point.
  • Balancing: The BMS may use the common port to discharge excess energy from higher voltage cells to lower voltage cells during the balancing process. Balancing helps ensure that all cells in the pack stay at a similar voltage level, improving overall pack longevity and performance.
  • Temperature Sensing: Some BMS units integrate temperature sensing as well. The common port could be connected to a temperature sensor to monitor the battery pack’s temperature.
  • Communication: Depending on the BMS model, the common port may also be used for communication with external devices or systems, such as a battery charger or an electric vehicle controller.

Please note that the specific wiring and connections can vary between different BMS models and manufacturers. Always refer to the user manual or documentation provided with your specific Daly BMS to ensure accurate and safe installation. Additionally, the specifications you provided (20S 50A) indicate that this BMS is designed for a 20-series LiFePO4 battery configuration with a maximum continuous discharge current of 50A
