Always match the voltage setting to the receiver and servo specifications.\u003c\/p\u003e\n\n\u003ch3 style=\"font-size:16px;font-weight:bold;color:#111;margin:18px 0 6px;\"\u003eCan Freewheeling be disabled on the SeaKing 200A V4?\u003c\/h3\u003e\n\u003cp style=\"margin:0 0 12px;\"\u003eYes. Freewheeling can be enabled or disabled through the HW LINK V2 app. The 300A HV V4 differs because its Freewheeling setting cannot be disabled.\u003c\/p\u003e\n\n\u003ch3 style=\"font-size:16px;font-weight:bold;color:#111;margin:18px 0 6px;\"\u003eDoes the SeaKing 200A V4 support reverse?\u003c\/h3\u003e\n\u003cp style=\"margin:0 0 12px;\"\u003eYes. The ESC supports Forward Only and Forward and Reverse running modes. Maximum Reverse Force can be adjusted, and the AUX channel can be assigned to modify reverse force through a compatible transmitter.\u003c\/p\u003e\n\n\u003ch3 style=\"font-size:16px;font-weight:bold;color:#111;margin:18px 0 6px;\"\u003eDoes the SeaKing 200A HV V4 include battery connectors?\u003c\/h3\u003e\n\u003cp style=\"margin:0 0 12px;\"\u003eNo. The ESC has red and black 8AWG battery input leads without a preinstalled connector. A suitable high-current connector must be installed for the intended battery system.\u003c\/p\u003e\n\n\u003ch3 style=\"font-size:16px;font-weight:bold;color:#111;margin:18px 0 6px;\"\u003eWhat motor connectors does the SeaKing 200A V4 use?\u003c\/h3\u003e\n\u003cp style=\"margin:0 0 12px;\"\u003eIt is supplied with three 10AWG motor output wires fitted with 6.5mm gold female bullet connectors.

Use matched, compatible batteries and properly rated wiring and connectors. Series wiring increases voltage rather than mAh capacity.\u003c\/p\u003e\n\n\u003ch3 style=\"font-size:16px;font-weight:bold;color:#111;margin:18px 0 6px;\"\u003eCan one SeaKing 200A V4 control two brushless motors?\u003c\/h3\u003e\n\u003cp style=\"margin:0 0 12px;\"\u003eNo. The ESC is designed for one compatible sensorless brushless motor.
