Description
The DALY BMS 16S 48V 20A LiFePO4 Battery Management System is a fixed 16S battery protection board designed for 48V LiFePO4 battery packs made from 16 cells rated at 3.2V each.
This BMS is specifically designed for LiFePO4 (LFP) battery chemistry and cannot be used with Li-ion, Li-Metal, or LTO batteries. The fixed 16S configuration makes it suitable for battery packs consisting of 16 LiFePO4 cells connected in series.
It provides essential protection against overcharge, over-discharge, over-current, short circuit, and temperature conditions. The integrated balancing function helps maintain more consistent voltage levels between individual cells during charging.
With a 20A continuous discharge current and 60±10A peak current, this BMS is suitable for low-to-medium current 48V LiFePO4 battery packs used in various power and energy storage projects.
