Improved Waterproof Sensor Interface
One of the most important changes in the MAX10 G2 is the redesigned sensored system. Hobbywing uses an improved waterproof sensor-cable interface together with upgraded sensored control to improve response while protecting the connection from the wet, dusty and dirty conditions commonly encountered by 1/10 trucks and monster trucks.
When paired with matching EZRun 3652SD / 3665SD G3 sensored motors, the ESC can operate as a complete sensored power system for smoother startup, more predictable low-speed control and stronger throttle connection.
Motor temperature protection note: Motor thermal protection requires a supported Hobbywing sensored motor such as the EZRun 3652SD or 3665SD G3. Do not assume motor-temperature protection is available with every third-party sensored motor.
140A Power for 3S and 4S 1/10 Builds
With a 140A continuous and 880A peak current rating, the MAX10 G2 140A sits well above ordinary sport-level 1/10 ESCs. It is intended for heavier tires, stronger motors and higher-load applications where acceleration and repeated throttle transitions place significant demand on the power system.
On 3S, Hobbywing recommends up to a 4000KV 3665-size motor under its standard application conditions. On 4S, the published guidance moves to a larger 4268-size motor at up to 2600KV.
These are application recommendations rather than a guarantee that every motor, gearing and tire combination within those numbers will operate safely. Vehicle weight, gearing, tire diameter, surface grip, ambient temperature and driving style can all change ESC and motor load.
Turbo Timing Up to 32 Degrees
The MAX10 G2 140A supports up to 32° of Turbo Timing. Turbo Timing adds electronic timing when the throttle reaches the configured condition, allowing additional motor RPM at the upper end of the throttle range.
When the MAX10 G2 is paired with the matched Hobbywing EZRun 3652SD / 3665SD G3 power system, Hobbywing promotes up to approximately 25% higher maximum speed under its referenced test and setup conditions.
That figure should not be treated as a guaranteed 25% vehicle-speed increase for every RC car. Actual speed depends on motor KV, gearing, battery voltage, battery voltage sag, tire diameter, vehicle load and aerodynamic drag. Higher Turbo Timing also increases current and temperature, so timing should be increased progressively rather than simply set to maximum.
Intelligent Freewheeling for Higher Efficiency
Hobbywing's intelligent freewheeling technology is designed to improve driving efficiency during partial-throttle operation. Compared with the previous MAX10, Hobbywing states that the G2 platform can operate at temperatures approximately 25°C lower under its referenced comparison conditions.
Lower operating temperature creates more thermal headroom during long bash sessions, repeated acceleration and high-load driving. It also reduces how much of the ESC's performance envelope is consumed simply dealing with heat.
74% Larger Capacitor Capacity
The MAX10 G2 also upgrades the power-conditioning side of the ESC. Hobbywing states that total capacitor capacity has increased by approximately 74% compared with the previous MAX10 generation.
A larger capacitor system helps handle rapid current changes between the battery and ESC during hard launches and repeated acceleration. The capacitor system also includes thermal protection, adding another layer of protection when the ESC is operated under demanding conditions.
Temperature-Controlled Frameless Cooling Fan
The MAX10 G2 uses Hobbywing's frameless fan design to move cooling air across the ESC's integrated heat-dissipation structure. The fan is temperature controlled rather than running continuously.
When ESC temperature is low, the fan remains off to reduce noise and electrical consumption. Once temperature reaches the programmed control threshold, the fan automatically operates to increase airflow.
IP67 Protection for Real RC Conditions
The MAX10 G2 power system is designed around an IP67-rated waterproof and dust-resistant architecture, making it suitable for the mixed conditions commonly encountered by trucks and monster trucks: wet pavement, mud, dust, sand, snow and water splash.
The upgraded sensor interface is especially important here because the sensor connection is traditionally one of the more exposed points in a sensored brushless system.
Waterproof use: Waterproof protection is intended to improve reliability during normal RC operation in wet and dirty environments. After wet running, inspect and dry the vehicle and connectors appropriately. Waterproof does not mean the complete power system should be left submerged for extended periods.
6V / 7.4V Adjustable 5A BEC
The built-in switch-mode BEC provides 5A continuous output with selectable 6V or 7.4V voltage.
This allows the MAX10 G2 to support both conventional receiver-side electronics and compatible high-voltage steering servos without automatically requiring an external BEC.
Always check the maximum operating voltage of the receiver, servo and other receiver-powered accessories before selecting 7.4V BEC output. Do not select 7.4V simply because the ESC supports it.
Real-Time Data Logging with Optional OTA Bluetooth
The MAX10 G2 140A supports Hobbywing HW LINK data monitoring, but unlike some newer Hobbywing ESCs, Bluetooth is not built directly into this ESC. An optional Hobbywing OTA Bluetooth module must be connected to the independent programming port.
Once connected, the HW LINK app can display operating information such as throttle position, ESC voltage, current, ESC temperature, motor temperature and RPM when supported by the connected system. Historical running data can also be reviewed through the data-log interface.

Battery Selection for 2S, 3S and 4S
The MAX10 G2 140A supports 2S through 4S LiPo. Battery selection should be based on the complete vehicle rather than ESC voltage support alone. Check the vehicle's battery tray, motor KV, gearing, connector system, battery wire routing, installed weight and expected current before choosing a pack.
For 4S builds, browse CNHL 4S LiPo Batteries. A higher-voltage battery should only be used when the motor, gearing and complete vehicle setup are appropriate for 4S operation.

Installation Notice
Before installation, confirm battery polarity, LiPo cell count, motor KV, motor size, gearing, tire diameter, receiver connection, BEC voltage, cooling, sensor-cable orientation and wire routing. When using a sensored motor, connect the A/B/C motor phases to the corresponding A/B/C ESC outputs and connect the sensor cable correctly.
Recalibrate the throttle range when the ESC is first installed, when changing transmitters, or after significant throttle-channel setting changes. Set the transmitter failsafe so the throttle returns to neutral or output is disabled if the radio signal is lost.
Always disconnect the LiPo battery after use. Do not select maximum Turbo, Punch or gearing simply because the ESC supports the setting; motor temperature, ESC temperature, battery load and drivetrain stress should be checked after setup changes.
