DALY LFP 11S 20A 3.6V BMS Hardware Lithium Battery

The DALY LFP 11S 20A 3.6V BMS is a Battery Management System (BMS) designed to manage and protect 11-series lithium iron phosphate (LiFePO4) battery packs. This BMS is ideal for applications requiring a moderate level of current, providing essential protection and monitoring features for lithium battery packs. Below is a detailed description of its hardware and features:

Key Features and Specifications:

1. Battery Configuration:
   • 11S Configuration: The BMS is designed for an 11-series battery pack, meaning it supports 11 individual LiFePO4 cells connected in series.
   • Nominal Voltage: Each LiFePO4 cell has a nominal voltage of 3.6V, which gives the overall pack a nominal voltage of 39.6V (3.6V × 11 cells).
   • Current Rating:
     • 20A Continuous Discharge Current: This BMS can handle a continuous discharge current of up to 20A, making it suitable for low- to medium-power applications where high current draw is not required.
     • Protection Features: The DALY LFP 11S 20A BMS incorporates several essential protection features to ensure safe operation of the battery pack:
       • Overcharge Protection: Protects the battery by disconnecting the charging circuit if any individual cell reaches a voltage above 3.65V, preventing overcharging and potential damage.
       • Overdischarge Protection: Disconnects the load if any cell’s voltage drops below a preset lower limit (typically 2.5V to 2.8V per cell), ensuring the cells are not excessively discharged, which could lead to capacity degradation.
