Restore the full electronic intelligence of your Husqvarna battery-powered professional tool with the genuine OEM BLDC Control Unit (Part #582054101). This is the genuine Husqvarna Control Unit BLDC (Mid spec) — the electronic brain that manages power delivery, motor speed, and operational modes in Husqvarna’s 36V professional battery series.

What Does the BLDC Control Unit Do? The Brushless DC (BLDC) Control Unit is the electronic motor controller that regulates battery input, manages cutting speed, handles load sensing, and enables advanced power modes like savE™. Without a properly functioning control unit, the brushless motor cannot receive accurate power signals — resulting in loss of cutting performance, failure to start, or unresponsive controls. This is a high-value, high-criticality component that must be replaced with a genuine OEM part to maintain the full safety and performance profile of your tool.

Why These Tools Demand Genuine OEM Parts: The 536LiHE3 is a battery pole hedge trimmer that combines petrol performance with zero emissions and extremely quiet operation, giving pro-level productivity and results — quiet and clean enough for use even in residential areas, hotels, hospitals and other noise-sensitive environments. The 536LiP4 is a battery pole saw for professionals with long 4m reach and performance that surpasses petrol equivalents. Both tools depend on their BLDC control unit to deliver that gas-equivalent performance — only a genuine OEM replacement can maintain that standard.
