120A Brushless Sensorless ESC for 2-4S LiPo

A 120A sensorless brushless electronic speed controller for high-power RC models with large brushless motors, running from 2–4S LiPo or 4–8S NiMH packs. It suits single-motor setups whose current draw is well beyond what a small FPV ESC is built for.

Key features

• Current handling: 120A continuous, with a 600A burst rating for peaks of up to 10 seconds.
• LiPo or NiMH: accepts 2–4S LiPo (7.4–14.8V nominal) or 4–8S NiMH (4.8–9.6V nominal).
• Sensorless control: drives standard three-phase brushless motors without a hall-sensor lead.

Specifications

• Continuous current: 120A
• Burst current: 600A (10 s)
• Input: 2–4S LiPo / 4–8S NiMH
• Motor type: Brushless, sensorless
• Size: approx. 52 × 42 × 40 mm

Check that your motor's peak current on the chosen battery and prop or gearing stays under 120A, and fit battery leads and connectors rated for that current. At 52 × 42 × 40 mm it needs a mounting spot with airflow over the case.
