BLS 80A 4-in-1 ESC – High‑Voltage Monster for 8S Rigs

Designed for extreme power systems, this 80A 4-in-1 ESC brings 8S capability and massive current headroom to large FPV drones, X-class racers, and heavy‑lift long‑range builds. With a rugged 30.5×30.5mm mounting format and high‑performance MOSFETs, it delivers relentless thrust without compromise.

Key advantages:

• 8S LiPo ready (3‑8S) – Unlock insane power for 7‑inch, 8‑inch, or even 10‑inch builds. Perfect for high‑speed long‑range or heavy payloads.
• Huge current capacity – 80A continuous and 90A burst (10 sec) per channel confidently drives massive motors like 2812, 3115, or 4215 without overheating.
• Compact yet powerful – At just 57×56mm and 28g, it fits standard 30.5×30.5mm stacks while handling serious amp draw – excellent power‑to‑weight ratio.
• Reliable EFM8BB21 MCU – Fast, proven processor with clean DShot signal handling for crisp throttle response.
• Supports DShot300/600 – Digital signal compatibility ensures low latency and easy setup with F4, F7, and H7 flight controllers.
• Pre‑tuned firmware – Ships with Q_H_40_24_v0.19.2 (BLHeli_S based), known for smooth motor synchronisation and reliable performance at high RPM.
• Built‑in current sensing – Scale 200 provides accurate real‑time amp and mAh readings in your OSD (telemetry output not available, but sensor data works via flight controller).
• Robust 4mm mounting holes – Standard pattern with larger holes for easy installation on thick frames.

Whether you’re building an 8S speed demon, a heavy‑lift cinema rig, or an unstoppable long‑range cruiser, this ESC gives you the voltage headroom and thermal margin you need to push harder.
