KAVAN Smart PRO-85HV SBEC – 80A High-Power Brushless ESC
The KAVAN Smart PRO-85HV SBEC is a high-performance electronic speed controller (ESC) designed exclusively for RC aircraft. Developed for demanding pilots and high-power applications, it delivers up to 80 A of continuous current at voltages up to 51 V (12S LiPo), while its powerful switching BEC provides up to 15 A of continuous output.
Compact, lightweight and highly configurable, the Smart PRO-85HV combines precise motor control, excellent efficiency and advanced telemetry. It is engineered to provide smooth and reliable performance even with high-power, multi-pole motors, making it an excellent choice for aerobatic and performance-oriented RC aircraft.
Why we like it at Aerobertics
At Aerobertics, we appreciate the KAVAN Smart PRO range for its combination of serious power, compact dimensions and intelligent configuration options. The 15 A SBEC, extensive telemetry support and advanced protection functions make the PRO-85HV a particularly versatile choice for demanding 12S setups.

Advanced Functions
The Smart PRO-85HV offers a range of additional functions for pilots looking for even greater control and performance:
- Active Freewheeling (synchronous rectification) can be enabled for improved motor response and reduced ESC heating during demanding aerobatic manoeuvres.
- Supports an optional external ON/OFF switch, push button, Hall sensor, RC switch or Touch Switch.
- Designed for reliable operation with high-power multi-pole motors and a wide range of other motor types.
- Optional backup battery connection without the need for additional adapters.
- Propeller positioning using a Hall sensor.
- Optional external motor identification chip combined with a temperature sensor.
Compact and Powerful
Despite its impressive power capability, the KAVAN Smart PRO-85HV remains remarkably compact at just 80 × 30 × 13.5 mm and weighs only 81 g.
This makes it an excellent solution when you need to combine high power with low weight and limited installation space.
