- Ultra-high reliability and durability - The robust hardware foundation, paired with enhanced software optimization, enables the ESC to deliver powerful performance while significantly reducing the risk of damage under high-load conditions. Integrated protection features, including low-voltage protection, over-temperature protection, throtle loss protection, and current overload protection, safeguard the ESC's reliability. These protection strategies are specifically designed for ship models, ensuring they are both practical and user-friendly. - IP67 Fully Waterproof Design - With an IP67 protection rating, this ESC boasts outstanding waterproof and dustproof capabilities. It can be used immediately without any additional waterproofing treatment. Note: The IP67 rating ensures protection against splashes, water, and dust under normal use. It has been tested under controlled lab conditions according to GB/T 4208-2017 (domestic) and IEC 60529 (international) standards. However, the protection is not permanent and may decrease with wear and aging -Capacitor overheating protection - The capacitor overheating protection mitigates the risk of damage to the ESC by preventing capacitor failure caused by overloading, thereby protecting the unit from potential complete failure. Note: SEAKING 30A V4 does not have capacitor overheat protection function.
