120A BL Marine ESC 2-6S Single Connector

The Dynamite 120A BL Marine ESC (DYNM3878) is a robust brushless speed controller designed for RC boats. Supporting 2–6S LiPo or 6–18 cell NiMH power, it features an IC5 battery connector and 5.5mm bullet motor outputs for straightforward, high-current connections. A switching BEC delivers a stable 6V at 5A continuous (10A burst) to reliably power receivers and servos, while forward, reverse and brakes give flexible control on the water.

Safety and tuning functions include programmable low-voltage cutoff, auto cutoff, overload protection and a time-delay brake. Low internal resistance (0.0005Ω) promotes efficient power delivery, and heavy-gauge 12 AWG battery leads help handle high current draw. Rated for 120A with up to 720A burst, this ESC is built for confident performance in demanding marine setups.
