Firma 130A 2-4S Black Edition Sensored Brushless Smart ESC V2 (SPMXSE2130)

Spektrum Firma 130A Smart ESC is a sensor-enabled, waterproof electronic speed control designed for 1/10-scale RC cars running on 2S–4S LiPo packs. It combines power regulation with one-wire telemetry to your radio, delivering real-time RPM, voltage, temperature, and battery data without extra sensors or wires. With a fast 32-bit ARM M4 processor and multi-point protection—over-current, automatic LiPo low-voltage cutoff, thermal protection, and failsafe—it's built to keep electronics performing at their best and lets tuning happen on the fly via button programming, the Smart ESC Programming Box, or USB updating.

Designed for 2WD and 4WD 1/10-scale surface vehicles, this ESC features a rugged plastic case with mounting tabs, an aluminum heat sink, and a cooling fan for efficient heat management. Ready to install—no soldering required. It includes an adjustable high-current BEC (6V or 7.4V at up to 4A) and uses IC-series connectors, with backward compatibility to EC connectors. It supports firmware updates and, when used with Spektrum Smart LiPo batteries, transmits battery telemetry to the transmitter in real time—offering visibility into cycles, remaining capacity, and per-cell voltage as you drive.
