BLS 90A 4-in-1 ESC – The Sweet Spot for 8S High‑Power Builds

Engineered for pilots who need serious current headroom without stepping up to the full 100A rating, this 90A 4-in-1 ESC delivers exceptional 8S performance in a compact 30.5×30.5mm stack. It’s the ideal choice for aggressive 7‑inch to 10‑inch long‑range rigs, X‑class racers, and heavy‑lift cinema drones.

Key advantages:

• 8S LiPo ready (3‑8S) – Harness the full potential of high‑voltage setups for blistering speed, extended flight times, or heavy payloads.
• Substantial current capacity – 90A continuous and 100A burst (10 sec) per channel confidently drives large motors like 2812, 3115, or 4010 with 7‑10″ props.
• Compact & lightweight – At just 57×56mm and 28g, it fits standard 30.5×30.5mm stacks while offering nearly double the rating of many 50‑60A ESCs in the same form factor.
• Proven EFM8BB21 MCU – Fast, reliable 8‑bit processor ensures crisp DShot signal handling and smooth throttle response.
• Supports DShot300/600 – Digital protocols provide low latency, easy configuration, and clean motor control with F4/F7/H7 flight controllers.
• Pre‑tuned BLHeli_S firmware – Ships with Q_H_40_24_v0.19.2, known for excellent motor synchronisation and rock‑solid performance at high RPM.
• Built‑in current sensor – Scale 200 delivers accurate real‑time amp draw and consumed mAh data directly to your OSD (ESC telemetry not available, but sensor output works via flight controller).
• Robust 4mm mounting holes – Standard pattern with larger holes for easy installation on thick frame plates.

Whether you’re building a no‑compromise 8S long‑range cruiser or a high‑thrust freestyle monster, the BLS 90A ESC gives you the perfect balance of power, weight, and thermal margin – without over‑specifying or overspending.
