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

Built-in Switchable BEC90A@18V constant output current, with built-in BEC output voltage selectable 5A@5.5V / 5A@7.5V. Whether it is a 2S or 4S battery, it always maintains stable voltage output even in the case of instantaneous high current. CL9030 can easily drive all kinds of standard and high-voltage servos and other external electrical equipment.

High PerformanceWith a 32-bit high-speed chip, high-frequency switch-mode chip MP9943 from MPS, and over 20 years of circuit design experience, CL9030 makes the throttle sensitivity up to 2000. Linear smooth control both forward and reverse is perfect for RC crawlers, drifting cars, and monster trucks.

Waterproof & Dust-rejected & Multiple ProtectionsAbnormal voltage input & low voltage cut-off protection for battery/Over-heating Protection/Over-input voltage Protection.

Wide Voltage CompatibilityInput voltage range 6-16.8V(for NI-MH, Ni-Cd, or lead-acid battery), 6-18V(for 2S-4S, Lithium Battery).

4 Working ModesBoat Mode, Training Mode, Racing Mode, and Crawler Mode. It can be set up easily through the jumper cap, no need program card. Works with most of RC radios and receivers, like RC6GS V3/RC4GS V3/RC8X/Dumborc X6/X4/DDF/Flysky GT5/Noble 4 and more.

NMOS H-Bridge Drive Design, Low Self-heatingThe CL9030 ESC uses the industry's innovative NMOS H-Bridge drive design, the internal resistance is much lower than that of the PMOS design commonly used in other ESCs, and massively reduces the heat during operation. CL9030 operates with minimal heat, eliminating the need for water cooling even in enclosed boat applications. Avoiding water-cooled components, not only saves space in the boat body (no water pumps or pipes required) but also avoids the risk of short circuits due to water-cooled failures
