Description
The DALY BMS LFP LiFePO4 8S 24V 80A is a fixed-configuration Battery Management System designed for 24V LiFePO4 battery packs using 8 series-connected 3.2V cells. It features a balance/sense cable for monitoring individual cells and supporting balanced charging.
This BMS is designed specifically for LiFePO4 battery packs and is suitable for applications requiring higher continuous discharge current. It provides protection against overcharging, over-discharging, excessive temperature, and short circuits while helping maintain balanced cell voltages.
The BMS is compatible with commonly used cylindrical and prismatic lithium battery cells, including 18650, 21700, and 36500 formats. It can be used in electric mobility, solar energy storage, RV systems, power tools, and other custom battery pack applications.
