Waterproof ZTW Beast 120A G2 32 Bit Sensorless ESC 4S With XT90 For 1:10 RC SCT
The ZTW Beast SL 120A G2 is a 32-bit waterproof sensorless ESC delivering 120A continuous and 760A burst on 2-4S LiPo. At 56×38×33mm and 128g with 12-gauge wiring, XT90, 4.0mm bullets, 6V/3A BEC, and cooling fan for high-power 1:10 RC.
ZTW Beast SL 120A G2 32-Bit Waterproof Sensorless ESC 2-4S with XT90 for 1:10 RC SCT, Monster Truck and Drag
120A High-Power ESC for Hard-Hitting 1:10 Rigs
The Beast SL 120A G2 is the most powerful 1:10 ESC in the SL lineup, delivering 120A continuous for heavy monster trucks, high-power SCT builds, and 4S speed runs where 80A is not enough.
120A Continuous / 760A Burst on 2-4S
With 120A sustained and 760A peak on 2-4S LiPo, this ESC drives 3665/3674-size motors with brutal acceleration and sustained high-speed power — massive headroom for big jumps, wheelies, and drag-style launches.
Wider 56mm Case with XT90 Connector
The larger 56×38×33mm housing provides extra surface area for heat dissipation, while the pre-installed Amass XT90 battery connector (up from XT60) handles the higher current of 120A operation.
12-Gauge Wiring & 4.0mm Bullets
Heavy-duty 12AWG power and motor wires with pre-soldered 4.0mm gold bullet connectors deliver current efficiently and install without soldering on most 1:10 setups.
32-Bit Processor & Smooth Delivery
The 32-bit MCU with new software provides accurate throttle output and excellent linearity, keeping high-power rigs controllable on loose surfaces while delivering explosive acceleration on demand.
Completely Waterproof & Dustproof
The fully sealed design handles the harshest bashing conditions — mud, snow, water, and dust — for year-round running.
Cooling Fan, BEC & Protections
Integrated cooling fan, 6V/3A BEC, and full protection suite. Program via LED card or optional Bluetooth APP with adjustable throttle/brake curves and drag brake.
