## Overview

The HOBBYWING SEAKING 300A HV V4 ESC is a high-performance, IP67 waterproof electronic speed controller designed for remote control boats up to 180cm. It delivers a continuous 300A current (peak 1600A), supports 5-14S LiPo batteries, and features a built-in Bluetooth module for seamless app-based programming and data logging. With a robust built-in BEC providing up to 25A at selectable voltages, this ESC ensures reliable power for high-torque servos while maintaining optimal cooling in a compact, durable package.

## Description

Excellent waterproof performance (IP67). Users can use it directly without any waterproof treatment. Note: If water enters during use, please blow-dry each plug to prevent rusting. The integrated Bluetooth function (built into the switch) allows for ESC settings and upgrades via the mobile app, without requiring additional devices, making it simpler and more convenient. Data logging functionality enables viewing of various running data through the HW LINK app. Supports firmware upgrades for the ESC, allowing access to the latest features.

Review: Absolute beast! - This thing is an absolute beast, purpose-built for handling those massive propellers that would melt lesser speed controllers. It delivers smooth, consistent, and brutal power. Do NOT skimp on your batteries. The 300A current draw means you absolutely must pair this ESC with top-quality LiPo packs that have a genuinely high C-rating (discharge capability). If you use mediocre or aged batteries, the SEAKING will draw so much current that it will rapidly stress and cook the battery, leading to puffing, failure, and potential safety issues. Bottom line: If you're ready for high voltage and huge props, this ESC delivers, but ensure your power source is just as capable!
Review: Its amazing - It’s a cool esc meaning it stays cool 11000 mah packs only last 6 minutes btw but it will stay cool no voltage cuts the whole time.
