▪High Discharge Ceiling: Supports a continuous discharge current of 40A, handling peak loads from heavy-duty motor drivers like the BTS7960 effortlessly.

▪Triple-Layer Defense: Integrated hardware protection against overcharge, over-discharge, and short-circuit scenarios.

▪Low Resistance MOSFETs: Uses high-quality, low-RDS(on) MOS transistors to minimize heat generation during high-current operation.

▪Improved Heat Dissipation: The "Enhanced Version" features a larger copper area and better thermal design compared to standard 20A/30A boards.

▪Automatic Recovery: Automatically restores power to the load once the fault (like a short circuit) is removed, preventing manual resets.
