High Reliability & Durability

Max4 HV is the most durable(hardware) and
advance(software) ESC on the market. The ESC is built
using the highest quality of materials available to withstand
extreme weather /surface conditions. Together with the
most advance software developed by our in-house
engineers, we have created multiple overloading functions
to protect the ESC from damaging.

High Reliability & Durability

Applicable to All Weather Track Conditions

The IP-67 waterproof system guarantees excellent waterproofing and dustproofing protection. The whole power system
is able to drive on a variety of surfaces including muddy, sandy, icy, snowy and water without damaging the power unit.

Capacitor Thermal Protection

Capacitor thermal protection implemented by the ESC will
effectively prevent capacitors from exploding and causing
irreversible damage to the ESC due to overload.

Thermal Protection

Superior Built-in BEC

The ESC has a built-in BEC which can support a maximum output current
of up to 25A and the output voltages are switchable between 6V,
7.4V and 8.4V. This ensures that the ESC is able to support the
demanding high-torque servos in the market.

Built-in spark-proof design

The built-in spark-proof circuitry is able to prevent damaging
the battery connectors as well as physical injury (to finger)
caused by strong electrical sparks upon connecting to a
“high voltage” battery pack (6-12S).

Advanced and Secured Electronic Switch

The all-new advanced and secured electronic switch features a longer lifespan compared
to the standard switch. The dust, dirt, and waterproof switch housing ensures reliable and
longer life and eliminates unwanted damages. Heavy impact or harsh surfaces will no
longer affect and damaged the switch. Users will be able to enjoy bashing their RC cars.

New sensored cable interface

The MAX4 HV ESC is equipped with a new type of
sensored cable interface. It is high recommended to use
the motors from Hobbywing as the waterproof protection
level is at the highest level (IP67).
