2S-4S Battery Supported, Constant Current 90A
2S-4S lithium battery or 5-12 NIMH batteries of power supply with constant 90A current output. Low voltage protection warning tone of lithium battery is in factory default setting.
Built-in Switching Regulator BEC, Efficient and Cool
The built-in switch BEC works with max output current 3A. No matter it is 2S or 4S battery with instant strong current, the output voltage will remain stable as 5.2V. No inefficient heating as linear battery nor output voltage jitter from sudden loading of ordinary switch power, COOL9030 can easily drive all kinds of standard and high-voltage servos and other external electrical equipment.
Compatible with All Model Cars/Boats
COOL9030 is a two-way (Forward/Reversal Rotating) ESC intelligently controlled by 32bits high-speed chip with control accuracy determined by 2000 throttle sensitivity. Working with linear brake and the mixed control function of Radiolink 6-CH radio for car RC6GS, COOL9030 is perfectly compatible with all model cars/boats including twin-engine models such as crawlers, drifting cars, tractor trucks and fishing boats.
High Efficiency & Low Temperature, Durable with Great Adaptability
Component of low resistance power and optimal driving voltage minimize the internal resistance and massively reduce the heat during operation.
The integrated net-shaped radiator cut with aluminum alloy CNC, assisted with aluminum sheet and fan to lose heat, maximizes the heat radiation effect. The best model performance can be always ensured even after a long time of high-speed driving or repeatedly slam on brakes.
Equipped with the advanced and safe electronic switch, COOL9030 resolves once and for all the problems of traditional mechanical switch including dusting, frequent languette stuck with humidity, contactor corrosion and accidental turn-off because of violent impact.
Brushed ESC for Cars & Boats
2KHz PWM Frequency
PWM frequency is set as 2KHz, meeting drivers’ needs of accurately adjust the forward power of motors. The advanced rectifier technology provides more outstanding experience of remote control.
Three Working Modes
There are three working modes: Car Mode, Racing Mode, Boat & Tank Mode.
Drivers can control models at various speed as wish because of the linear throttle and brake, which is much smoother and more sensitive than traditional ones.
Car Mode (RED):
When the car is forwarding, push the throttle back to center for a short period (0.5 to 1s) to brake. Then push the throttle further for car backward.
Racing Mode (GREEN):
Forward/Brake. NO backward.
Boat &Tank Mode (BLUE):
Forward/Backward and Brake Type is optional. (The brake function can be turned on/ off by itself, and the reverse operation cannot be performed when pushing the throttle back to center)
The indispensable brake function for model cars is the obstacle to boat control so this mode is more suitable for boat. The extreme low heating of both motors and BEC ensures the long dependable use even in sealed environment.
COOL9030 has the protection function of lithium battery over discharge, over temperature and abnormal voltage input.
Battery over discharge protection:
When the battery voltage is lower than 3.7V, the output power will be reduced gradually. When lower than 3.2V, the power will be cut to protect the model battery and prevent lithium battery from over discharge.
Over temperature protection:
When the ESC temperature reaches 100°C, the car/boat speed will decrease to half of the max of normal condition. When the ESC temperature reduces to 60°C， the model speed will be back to normal.
Abnormal voltage input protection:
The max battery input to COOL9030 is 4S lithium. When it’s over 18V, the ESC won’t be activated.
Personalized Lithium Battery Protection Function
Enable low voltage protection function: Long press ESC power button, a Dee sound is heard and the green led flashes twice means low voltage warning is enabled. When the voltage of a single cell is lower than 3.7V, a constant DEE sounds will be heard. When it’s lower than 3.2V, the ESC will be automatically powered off. The Kalman Filter technology applied in COOL9030 can accurately identify in real-time the instant voltage when power on and rotors locked.
