Firma 150A Brushless Smart ESC V2, 3S - 6S: Dual IC5

Firma 150A Brushless Smart ESC V2 for 3S–6S packs is a high-performance electronic speed controller designed for brushless RC systems. As part of the Firma Smart ecosystem, it provides one-wire telemetry that streams essential data—RPM, voltage, temperature, and battery status—directly to a compatible transmitter, enabling real-time monitoring and on-the-fly tuning of your setup.

Designed for straightforward installation, the ESC arrives ready to drop into most models without soldering. It features a rugged plastic housing with mounting tabs, an aluminum heat sink, and an onboard cooling fan to keep temperatures in check, plus an adjustable high-power BEC to power the receiver and servos. Dual IC5 connectors simplify battery wiring and maintain compatibility with IC3/IC5 cables. Multiple programming options—button programming, the Smart Firma ESC Programming Box, and the PC/Mobile Smart Link USB updater—let settings be tuned at the track or in the workshop. The waterproof design, along with protections for over-current, low-voltage cutoff, thermal events and failsafe, helps protect both the ESC and motor across varied conditions, and a 1-year limited warranty provides added assurance.
