150A ZTW Beast ESC 32 Bit Waterproof Sensorless 2S-6S ESC Controller

ZTW Beast SL 150A G2 32-Bit Waterproof Sensorless ESC 2-6S with XT90 for 1:8 RC Buggy, Truggy and Monster Truck

150A 6S Waterproof Power for 1:8 RTR

The Beast SL 150A G2 is the flagship of the SL lineup, bringing 6S capability and 150A output to 1:8 buggies, truggies, and monster trucks. A high-value RTR power system with big-scale performance.

150A Continuous / 1080A Burst on 2-6S

150A sustained and 1080A peak across 2-6S LiPo (5-18 NiMH) drives 4068/4074-size motors with massive torque and high-speed capability — from 4S bashing to 6S speed runs.

32-Bit Processor for Accurate Power

The 32-bit microprocessor provides more powerful data processing and more accurate throttle output, with excellent startup, acceleration, and linearity across the full 2-6S voltage range.

6.0/7.4V Adjustable 6A BEC

The adjustable switching BEC delivers 6A at 6.0V or 7.4V — enough to power high-torque 1:8 digital servos for steering and shifting, with selectable voltage to match HV servo specs.

10-Gauge Wiring & 5.0mm Bullets

Heavy-duty 10AWG power and motor wires with pre-soldered Amass XT90 battery connector and 5.0mm gold bullet motor connectors handle extreme 1:8 currents with minimal voltage drop.

Completely Waterproof & Dustproof

The fully sealed ESC handles mud, snow, water, and dust — built for 1:8 bashers and RTR vehicles that see extreme off-road conditions.

Cooling Fan, Programming & Protections

Integrated cooling fan maintains thermal headroom. Program via LED Program Card G2 or optional Bluetooth APP. Low-voltage cutoff, over-temperature, signal-loss, and stall protection included.

FAQ
1. What are the continuous current and peak current of this ESC?

A: The ZTW Beast SL 150A G2 has a continuous current of 150A and a peak (instantaneous) current of up to 1080A. This extremely high peak current capability is designed for the extreme driving scenarios of 1:8 scale off-road vehicles, racing trucks, and monster trucks, providing powerful torque output under instantaneous high-load conditions such as rapid acceleration and landings from steep inclines, driving 4068/4074 brushless motors.

2. How many lithium batteries does it support? What types of vehicles is it suitable for?

A: This ESC supports 2S to 6S lithium batteries (compatible with 5-18 NiMH batteries). Whether it's everyday off-road driving with a 4S battery or high-speed driving with a 6S battery, it can handle it with ease. It is designed for 1:8 scale RC vehicles, including buggies, racing trucks, and monster trucks, and is also suitable for some large 1:10 scale vehicles.

3. What is the output capability of the built-in BEC? Can it power high-voltage servos?

A: This ESC has a built-in 6A switching SBEC, with an output voltage that can switch between 6.0V and 7.4V. The 7.4V output is sufficient to drive the high-torque, high-voltage digital servos required for 1:8 scale vehicles, ensuring crisp and powerful steering and shifting. Even under high-load maneuvers such as sharp turns, the 6A high-current output effectively prevents voltage drops (browout) in the receiver and servos.

4. Is this ESC waterproof? Can it be used in rain or on muddy roads?

A: Information regarding waterproof performance varies slightly depending on the source. Please note:

ZTW's official website states it is "Completely water-proof and dust-proof."

The Amazon product page describes it as "Water-Resistant & Splash-Proof," explicitly stating that the PCB board has a waterproof coating to withstand splashes from puddles, mud, and morning dew. However, immersion in water will cause damage and is not covered under warranty.

Recommendation: This ESC is suitable for off-road driving in wet and harsh conditions such as rain, mud, and snow, but it is not recommended to completely immerse it in water or use it for diving.

5. How do I program and set parameters for this ESC?

A: The ZTW Beast SL 150A G2 supports multiple programming methods, offering great flexibility:

Mobile App Programming: With the optional ZTW Bluetooth module, parameters can be adjusted via a mobile app (supports iOS and Android).

LED Programming Card G2: Parameter settings are made using the dedicated ZTW LED Program Card G2.

Remote Control Joystick Programming: Basic parameter settings can also be made via the remote control throttle joystick.

Please note: The Bluetooth module and LED Programming Card G2 are sold separately and are not included with the product. Furthermore, this ESC does not support firmware upgrades.

6. What safety protection features does this ESC have? What are the cable and connector specifications?

A: This ESC is equipped with a comprehensive 4-layer intelligent protection system:

Low-voltage cutoff
Over-heat/Thermal protection – activates when the temperature reaches 105°C
Locked-rotor detection
Signal-loss protection
Cable and connector specifications:

Power cable: 10AWG diameter
Battery connector: Pre-installed Amass XT90 connector
Motor connector: 5.0mm gold-plated banana plug
Built-in cooling fan: Integrated cooling fan helps maintain thermal management
