T-Motor Velox F7 SE 8S + V70A SE 8S 4IN1 ESC Stack
Extreme power and stability in every second of flight thanks to T-Motor Velox F7 SE 8S + V70A SE 8S 4IN1 ESC Stack
The T-Motor Velox F7 SE 8S + V70A SE 8S 4IN1 ESC Stack is a professional power and control solution designed with modern FPV drones in mind. With full support for up to 8S voltage, the stack provides an incredible power reserve and operational stability even at maximum throttle opening. The multi-layer PCB power-layer design reduces the board's current-carrying limitations. A built-in Bluetooth module and a modern ICM-42688P gyroscope guarantee lightning-fast configuration and remarkably smooth drone responses to stick movements, and the flight controller also carries a DPS310 barometer.
Intuitive Plug-in signal installation in
T-Motor Velox F7 SE 8S + V70A SE 8S 4IN1 ESC Stack
Assembly and servicing of the electronics become extremely simple thanks to the use of a Full Plug-in Design for all signal connections in the T-Motor Velox F7 SE 8S + V70A SE 8S 4IN1 ESC Stack. All wiring connecting the flight controller (FC) to the electronic speed controller (ESC) strictly follows plug standards compatible with Betaflight. This eliminates the need for complicated and time-consuming soldering of tiny signal wires, drastically reducing the risk of error and keeping platform build time to a minimum.

Optimized 70A Multi-Layer PCB
The ESC features an optimized multi-layer PCB designed to handle 70A continuous current. Its power-layer design reduces the board's current-carrying limitations, so high current flows with fewer bottlenecks under sustained heavy loads.
Unmatched 8S Power Reserve
The innovative design of the T-Motor Velox F7 SE 8S + V70A SE 8S 4IN1 ESC Stack officially supports 8S battery packs. This upgrade raises maximum power for stronger thrust by up to 50%, radically transforming freestyle flight dynamics. Additionally, the higher voltage headroom guarantees safe and stable electronics operation during extreme throttle inputs.
Upgraded 3rd Gen BEC System
The integrated 3rd generation BEC power system reduces ripple voltage by 50% compared with the previous generation. Cleaner power means less electrical interference reaching the gyro, for more precise sensor readings and better noise filtering by the flight controller.
T-Motor Velox F7 SE 8S + V70A SE 8S 4IN1 ESC Stack Key Features
- Up to 8S power supply support: Provides a massive power reserve and stable operation under heavy loads
- 70A continuous current: A reliable 4-in-1 ESC based on modern AM32 firmware handles the most demanding motors.
- Multi-layer PCB: An optimized power-layer layout reduces the board's current-carrying limitations.
- Advanced 3rd generation BEC: Reduces voltage ripple by up to 50%, delivering a clean signal to sensitive components such as the flight controller or video system.
- Bluetooth wireless connectivity: Allows for convenient tuning, blackbox analysis, and full Betaflight configuration directly from a smartphone.
