Overview

6S LiPo Compatibility

The Hobbywing MAX8 ESC manual notes that the warranty does not extend to issues resulting from 6S LiPo configurations. Please visit the Hobbywing website for information and consult the manual for proper operation guidelines.

The Ezrun MAX4 ESC works best with the included 70125 SD 560kV motor for extra large 1/4 and 1/5 scale models. This fully sensor-controlled combo can be used in many ways in such models, whether it's a heavy-duty off-roader or a truck.

So if you like large models and you want the most fun out of it, the MAX4 combo is high-quality equipment that literally bursts with exploding power. And even with its enormous size, care was taken to use high-quality and, above all, durable materials in the construction. After all, both the ESC and the motor should ensure that driving fun lasts as long as possible. Even the electronic switch is well protected against damage. In addition, the Ezrun MAX4 has a built-in super high-current BEC, which can provide a max. output power of up to 25A. The output voltage can be switched between 6V, 7.4V and 8.4V. The high-current BEC was developed in such a way that it can supply the current high-current servos with sufficient power if required, and thus be able to precisely control the appropriate large models.

Features

  • Full sensored combo
  • Super powerful switch mode BEC with a constant current of 10A, instant 25A and the ability to switch between 6V, 7.4V and 8.4V
