High-performance 60A brushless ESC with BLHeli firmware. Optimized for 5-7" drones, supporting 3-6S LiPo and advanced digital protocols like DShot600.
Master high-power flight with total authority. The BLHeli Series 60A Brushless ESC is engineered for pilots who demand reliability under heavy loads. Whether pushing a 5-inch racing quad at full throttle or cruising a 7-inch long-range platform through the mountains, this ESC’s 60A continuous rating ensures your power system remains stable without thermal runaway.
Probots™ ProSpec Grade Reliability This ESC is Probots™ ProSpec Grade, featuring oversized MOSFETs and a multi-layer copper PCB to dissipate heat efficiently during sustained high-current draws. The 4-in-1 design integrates four individual ESCs into a single compact footprint, significantly reducing wiring clutter and overall build weight. Advanced digital signal support, including DShot600, allows the flight controller to communicate with the motors with microsecond precision, virtually eliminating desync issues.
Continuous Current: 60A
Burst Current (5-10s): 65A - 70A
Input Voltage (LiPo): 3S to 6S
Firmware: BLHeli_S or BLHeli_32 (Model Dependent)
Supported Protocols: DShot150/300/600, MultiShot, OneShot
Mounting Pattern: Standard 30.5mm x 30.5mm (M3/M4)
Integrated Sensors: Galvanometer (Current Sensor) and Battery Telemetry
5-7" Long-Range Drones: Perfect for platforms using large low-KV motors like 2806.5 or 3115.
FPV Freestyle & Racing: Provides the explosive punch and rapid recovery required for technical acrobatic flight.
Heavy-Lift Micro-UAVs: Reliable lift for drones carrying gimbals or specialised cinema cameras.
Unlock New Capabilities (Project Evolution)
Feature Upgrade: The integrated current sensor allows for real-time monitoring of "mAh consumed" in your FPV goggles, helping you land with precision every time.
Effort Level: Intermediate. Requires precise soldering for the main power leads and 12 individual motor phase wires.
Package Includes:
1 x 60A 4-in-1 Brushless ESC
What is the maximum battery cell count? It is fully compatible with 3S to 6S LiPo batteries.
Does it have an integrated BEC? Most 4-in-1 60A ESCs do not have a BEC to keep noise low; ensure your Flight Controller has an integrated BEC to power your electronics.
Why do I need to solder the included capacitor? It suppresses voltage spikes from the motors, protecting your ESC and Flight Controller from electrical noise.
What motor size is best for this 60A ESC? It is ideal for 2207, 2306, 2806.5, and 3110 brushless motors.
Does it support the DShot600 protocol? Yes, it supports DShot150/300/600 for high-speed digital communication.
How do I reverse the motor direction? You can change motor direction digitally via the BLHeliSuite software or the Betaflight configurator passthrough.
What is the burst current rating? It can handle 65A–70A for short 5–10 second bursts.
Is it waterproof? No, it is a bare PCB unit. Use a silicone conformal coating if you plan to fly in damp conditions.
What mounting size does it use? It uses the standard 30.5mm x 30.5mm mounting pattern.
Does it include a current sensor? Yes, it typically includes an onboard galvanometer for live current telemetry.
Why use a 4-in-1 ESC instead of 4 individual ESCs? It reduces weight, simplifies wiring, and centers the mass of the drone for better flight dynamics.
Can I use this on a 2S setup? Most 60A models require at least 3S to power the onboard circuitry.
How do I calibrate the throttle? If using digital protocols like DShot, throttle calibration is disabled and unnecessary; for analog protocols, use the Betaflight motor tab.
What is the weight of the unit? Approximately 13 to 15 grams.
Does it support telemetry? Yes, it provides battery voltage and current sensor data to the Flight Controller.
Is it compatible with 32-bit firmware? Depending on the model, it may run BLHeli_S (8-bit) or BLHeli_32 (32-bit).
What happens if I connect the battery backward? The unit has no reverse polarity protection; connecting it backward will cause instant and permanent damage.
Can I use this for a 7-inch long-range build? Yes, it is one of the most reliable choices for 7-inch platforms.
What gauge wire should I use for the battery? We recommend 12AWG or 14AWG high-quality silicone wire.
Can I update the firmware? Yes, firmware can be updated using BLHeliSuite32 or the BLHeli Configurator via the Flight Controller.
