Seboar BL_S 4-8S 100A 4-in-1 ESC

The Seboar BL_S 4-8S 100A 4-in-1 ESC is a high-performance electronic speed controller designed for FPV drones and multirotor UAV platforms.

By integrating four ESC channels on a single board, the system simplifies wiring and improves overall reliability in drone builds.

Running BLHeli_S firmware, the ESC provides fast throttle response, smooth motor operation, and stable flight performance.
Its high current capacity and wide voltage range allow it to power demanding drone setups using large motors and high-capacity batteries.

The compact design and standard mounting hole pattern make it compatible with most modern flight controllers and FPV stacks.

Typical applications include:

FPV racing drones

freestyle drones

long-range FPV platforms

industrial multirotor UAVs

Key Features

High-Current 100A Output

Each ESC channel supports 100A continuous current, enabling powerful drone propulsion systems.

BLHeli_S Firmware

The ESC runs BLHeli_S firmware, providing smooth throttle response and reliable motor control.

Compact 4-in-1 ESC Design

Four ESC channels are integrated into a single board, reducing wiring complexity and improving drone assembly efficiency.

Wide Voltage Compatibility

Supports 4–8S LiPo battery input, making it suitable for high-performance drone power systems.

Flight Stack Compatibility

The ESC uses the widely adopted 30.5 mm mounting pattern, ensuring compatibility with most flight controllers.
