SKYBIT PDB500x Power Distribution Board

The SKYBIT PDB500x is a high-current power distribution board built for large-format multirotors, X-Class builds and industrial or agricultural drones that draw well beyond the limits of a standard FPV PDB. Rated for 500A total, it feeds four heavy-duty ESC outputs at up to 125A continuous each with minimal heat build-up.

Key features

• Accepts a wide 12–60V (4–14S) input, covering everything from 6S freestyle rigs to high-voltage 14S industrial power systems.
• Four ESC outputs rated at 125A continuous each keep large stators fed without excess voltage drop.
• Regulated 12V and 5V rails (5A total each) power flight controllers, cameras and accessories without a separate BEC.
• Wide -20°C to +85°C operating range suits outdoor industrial and agricultural use.
• 30.5x30.5mm mounting matches the standard flight-stack pattern for straightforward integration.

Specifications

Built for custom high-draw multicopters where a standard FPV PDB cannot safely carry the sustained current of large motors; match your wire gauge to the ESC's continuous draw before soldering.
