Description
The DALY BMS 8S 24V 100A LiFePO4 Battery Management System is designed to protect and manage an 8S LiFePO4 battery pack made from eight 3.2V cells, providing a nominal 24V battery configuration.
This is a fixed 8S BMS and is designed exclusively for LiFePO4 batteries. It should not be used with Li-ion, Li-Metal, or LTO battery packs.
The BMS provides essential battery protection functions, including overcharge, over-discharge, over-current, short-circuit, and temperature protection. Its built-in balancing function helps maintain better voltage consistency between individual cells during charging.
With a 100A continuous discharge rating, this DALY BMS is suitable for high-current 24V LiFePO4 battery applications such as electric bikes, solar power systems, RVs, power tools, and energy storage systems.
