  • Weight: Not Specified

Detail

The FETtec 4in1 ESC 45A is a 4-in-1 ESC based on the STM32G071 (64MHz), built with high-quality 40V MOSFETs and featuring active current limiting. It supports a 3S-6S LiPo input voltage. It comes with proprietary FETtec firmware and supports KISS and Betaflight passthrough (from Betaflight 4.1 onward). The integrated current and voltage sensor provides serial telemetry through the TLM pad. An additional capacitor is required for 5S and 6S operation; the board provides up to five additional capacitor soldering points, and the required capacitor (50V, ESR<1ohm) is included in the package. Note: Regarding the mounting hole spacing, the official product page states "30.5x30.5mm", while the official manual specifies "30x30mm"; there is a minor discrepancy between the two official sources, so both are listed. Weight information is not provided by any official source.
