Radiolink CL9030 90A (2S-4S) Brushed ESC Waterproof Built-in 5A BEC Selectable 5.5V/7.5V Electronic Speed Controller for RC Crawlers Tanks Cars Boats (XT60 Plug)

Features

• 【90A Brushed ESC】– Supports continuous current of 90A and peak current of 100A, ensuring powerful and reliable motor control for cars and boats. Designed for 1/10 RC crawlers/trucks/buggies/tanks/boats/bait boats.
• 【High Performance】– With a 32-bit high-speed chip, high-frequency switch-mode chip MP9943 from MPS, and over 20 years of circuit design experience, it makes CL9030's throttle sensitivity is up to 2000, linear and smooth control forward and reverse running.
• 【Precise PWM Control 】– Features a 2KHz PWM frequency, and it can be accurately adjusted to control the forward power of motors. The advanced rectifier technology provides the more outstanding experience of remote control.
• 【Wide Voltage Compatibility】– Operates smoothly within a 6V to 18V input range; supports both lithium and non-lithium batteries (NI-MH, Ni-Cd, or lead-acid battery) with jumper cap configuration for safe and optimized battery usage. Insert Jumper cap 3 when using a lithium battery, and remove Jumper cap 3 when using a non-lithium battery. Wrong state of Jumper cap 3 may cause serious over-discharge of the battery and damage the battery. Be sure to check Jumper cap 3 to confirm the battery type of the ESC before use.
• 【Smart Protection Features】– Equipped with under-voltage, abnormal voltage input, and over-temperature to prevent battery damage and extend ESC lifespan; CL9030 brushed ESC with Nano Coating to have a water-proof (IP66) and dust-proof design, allowing CL9030 to have reliable performance on different terrains running.
• 【Low Self-heating】– The CL9030 ESC's innovative NMOS H-Bridge design, an internal resistance that is much lower than that of the PMOS design. No need for water-cooled components even in enclosed boat applications. It saves space in the boat's body and also avoids the risk of short circuits due to water-cooled failures.
• 【Easy to Set Up】– Working mode switch (Training Mode, Racing Mode, and Crawler Mode), lithium battery protection, 5V or 7V BEC selection setting by jump caps, especially applicable to new beginners.
