ZTW BX 80A 4-in-1 AM32 ESC 4S-8S 7kg Payload for 10–13The ZTW BX-80A 4-in-1 AM32 ESC

High-Current 4-8S for 10–13 Inch Builds

The 80A 4-in-1 steps up to 4-8S LiPo support and 80A continuous (100A burst) per channel, making it ideal for 7–10 inch long-range, cinematic, and heavy-lift freestyle quads. It comfortably drives 2810–3115 class motors on 6S–8S for extended flight times and high payload capacity.

7kg Payload Rating

Rated for multirotor platforms up to 7kg total weight, the 80A transitions seamlessly from hobby long-range flying to light commercial applications — aerial photography, surveying, and small cargo delivery. The 30.5×30.5mm/M4 footprint is the industry standard for mid-to-large flight controllers.

120MHz Processor with Bidirectional DSHOT

The AT32F421 at 120MHz delivers bidirectional DSHOT300/600 with zero latency, unlocking Betaflight RPM filtering for buttery-smooth flight even on large, high-inertia props. Stable RPM telemetry is especially valuable on 8-10 inch frames where motor noise can otherwise degrade gyro performance.

Dual Capacitors for Clean 8S Power

Two 2200µF low-ESR capacitors keep voltage rails stable under 8S full-throttle loads, preventing brownouts and reducing ESC heat. 10AWG power leads with an Amass XT90 plug handle the higher current without voltage drop.

AM32 Open-Source Firmware

Running AM32 with web-based configuration, the 80A is tunable for any motor/prop combination — from efficient long-range cruising to aggressive freestyle. At 27g and 57×54×6.5mm, it remains compact enough for 7-inch builds while delivering 10-inch capability.
