DALY Li-ion NMC 6S 24V 15A Waterproof Battery Management System - BMS Protection Board is a 6-series DALY Battery Management System designed for NMC (ternary lithium) battery packs in the 24V class. The unit shown is rated for 15A charging and 15A discharging and uses a common-port architecture with B- and P- connections. It provides protection against overcharge, over-discharge, over-current, short circuit, and abnormal temperature conditions, while its integrated passive balancing function helps maintain cell-voltage consistency during charging. The waterproof-style enclosed construction provides additional protection for battery-pack applications. DALY documentation lists passive balancing as a standard BMS function and identifies the J13G3 family as supporting Li-ion/LiFePO4 configurations, with the exact chemistry selected according to the BMS version.
