* Battery is included with selected variants. Please check your order specification for details.

⚠️ Safety Note

Brake fluid is corrosive to paint and skin. Always wear protective gloves when testing, and clean any spilled fluid immediately. A moisture content above 4% significantly reduces brake fluid boiling point and can cause brake failure under heavy use, leading to serious accident risk. Always replace contaminated brake fluid immediately when indicated by the tester.
