Description
The DALY BMS LFP LiFePO4 8S 24V 30A is a fixed-configuration Battery Management System designed specifically for 24V LiFePO4 battery packs made from 8 series-connected 3.2V cells. It includes a balance/sense cable for monitoring individual cell voltages and maintaining better balance during charging.
This BMS is strictly designed for LiFePO4 battery chemistry and cannot be used with Li-ion, Li-Metal, or LTO batteries. It helps protect the battery pack from overcharging, over-discharging, excessive temperature, and short circuits.
The BMS is suitable for cylindrical and prismatic LiFePO4 cells, including commonly used 18650, 21700, and 36500 cell formats. It can be used in custom battery packs for electric mobility, solar power, energy storage, and other applications.
