Firma 160A Smart Brushless Marine ESC (SPMXSE1160M)

The Firma 160A Smart Brushless Marine Electronic Speed Controller is a high-performance ESC built for demanding RC boat setups. It regulates power to brushless motors with a 160A continuous rating and supports up to 8S LiPo input, delivering precise throttle control and reliable operation under load. As part of the Firma Smart ecosystem, it communicates telemetry directly to a compatible transmitter, providing real-time data such as RPM, voltage, temperature, and battery capacity to optimize performance on the fly. The unit is designed for marine use with a waterproof seal and proactive heat management, including support for water cooling to keep temperatures in check during long, high-speed runs; saltwater use is not recommended.

For straightforward installation, the ESC comes in a compact case with mounting tabs and an aluminum heat sink, plus multiple water-cooling inlets and outlets for efficient cooling at high current. Programming is flexible—button programming on the unit, the Smart ESC Programming Box, and a PC programmer app make tuning quick at the dock or in the shop. Robust protections—including over-current, LiPo low-voltage cutoff, thermal protection, and a failsafe—help prevent damage in fault conditions. It uses high-heat IC5 connectors that are backward compatible with EC3/EC5, includes a high-current 6V BEC, and firmware updates keep features current. A limited one-year warranty accompanies the unit.
