ZTW BX-100A Drone 4 In 1 ESC BLHeli-S 3S-8S DShot600 X8 10kg Payload Multirotor ESC

ZTW BX-100A 4in1 ESC BLHeli-S 3-8S DShot600 with 8-Layer 4oz Copper PCB for 15 Inch Heavy-Lift, X8 and 10kg Payload Multirotor

100A Per Channel for 15 Inch & 10kg Payloads

The BX-100A 4in1 is the most powerful BLHeli-S ESC in the BX lineup, delivering 100A continuous and 120A burst per channel — built for 15 inch heavy-lift multirotors, X8 coaxial platforms, and large professional aerial systems carrying up to 10kg payload.

Upgraded 8-Layer 4oz Copper PCB

The board is upgraded to an 8-layer, 4-ounce thick copper PCB — beyond the 6-layer 3oz construction of the 60A/80A — maximizing current delivery and heat dissipation under extreme sustained loads when four motors draw up to 480A combined.

Same Footprint as 80A, 50% More Current

Shares the identical 57×54×6.5mm, 25g footprint as the BX-80A but uses upgraded power MOSFETs and the heavier 8-layer 4oz board to deliver 120A — a direct high-current drop-in upgrade for airframes already running the 80A without mechanical redesign.

3-8S High-Voltage Operation

Handles 3S to 8S LiPo, supporting high-voltage heavy-lift setups that benefit from reduced current draw and improved efficiency at the 10kg payload level.

BLHeli-S & DShot600

BLHeli-S firmware with damped-light braking provides smooth, reliable motor control. Full DShot150/300/600, Oneshot, Multishot, and PWM compatibility works with any modern flight controller and protocol stack.

Pre-Soldered XT90 & Dual FC Cables

Amass XT90 connector and dual SH1.0 8-pin FC cables come pre-soldered, reducing assembly time and ensuring high-reliability connections on high-current professional builds.

Built for Demanding Missions

The combination of class-leading current density, 8-layer 4oz copper construction, wide voltage range, and extended temperature tolerance makes the 120A suited for professional and industrial multirotor platforms operating in challenging environments where downtime is not an option.
