Intelligent Thermal & Management

The front panel integrates an advanced dual-color LED diagnostics system controlled by an internal MCU for real-time tracking of the smart battery charging profile curve:

• Solid Red (Standby): Power On / No Battery Detected.
• Blinking/Cycling Red to Green (Active): Safe execution of Pre-charge / CC / CV phases.
• Solid Green (Finished): Auto Cut-off active; battery at 100% capacity. Safe for long-term float connection.
• Flashing Alternately (Fault): System Error Latch (Output Short-circuit, Reversed Polarity, or Thermal Overload).
