4in1 ESC (45A and 60A variants) for 26S LiPo, DShot600 Compact, performance 4in1 ESC module designed for multirotor aircraft that require a small footprint, straightforward installation, and support for fast digital protocols. Available in a 45A continuous current version and a highercapacity 60A continuous version with a 5second burst rating of 70A. Key benefits Space and wiring savings: Integrates four ESC channels into a single board to reduce wiring complexity and save stack height and weight in compact builds. Stable power delivery: Builtin filter capacitor reduces back EMF, stabilizes battery voltage, and protects sensitive ESC components for improved reliability under variable load. Fast, precise control: Supports DShot600 digital protocol for lowlatency, reliable communication with compatible flight controllers. Flexible mounting: Standard 30.5 x 30.5 mm mounting hole spacing with M4 holes and support for M3 shockabsorbing posts, making it easy to fit into common frame layouts. Specifications Variants: 45A continuous 4in1 ESC; 60A continuous 4in1 ESC (5second burst 70A) Input voltage: 2S to 6S LiPo Protocol: DShot600 Dimensions: 39 x 41 mm Mounting hole spacing: 30.5 x 30.5 mm Mounting hardware: M4 mounting holes; supports M3 shockabsorbing post mounting Onboard components: Filter capacitor included to suppress reverse electromotive force and stabilize battery voltage No galvanometer: No builtin current sensor No BEC: No onboard regulated power output; external power source required for flight controller and peripherals Firmware: J_H_30_REV16_7 Practical use scenarios 5inch racing or freestyle quad built for agility and low stack height: Use the 45A or 60A variant depending on motor and prop selection to achieve compact, reliable power delivery. Midsize longflight or heavypayload builds operating on 4S to 6S: Select the 60A variant to provide higher continuous current and shortterm burst capacity for heavy throttle demands. Replacement or upgrade in compact stacks: Swap a bulky multiboard setup for a single 4in1 unit to simplify wiring and improve system neatness while maintaining DShot600 compatibility. Notes for installation and setup Confirm required external power for flight controller and peripherals since there is no onboard BEC. Verify motor and prop combinations do not exceed the continuous current rating of the chosen variant. Use the 30.5 x 30.5 mm M4 mounting pattern or M3 shockabsorbing posts as appropriate for your frame. This 4in1 ESC provides a balance of compact size, digital control performance, and stable power conditioning suitable for a wide range of multirotor designs.
