🔧 Market Background & Demand

With the rapid growth of automotive repair, construction, steel structure assembly, and electrical installation, the global power tool market is expanding significantly. Among these tools, impact wrenches are indispensable for their high torque, portability, and efficiency, widely used in:

• 🚗 Automotive workshops (tire replacement, chassis maintenance)
• 🏗️ Construction sites (steel bolt fastening)
• ⚡ Electrical installations (high-altitude operations, distribution equipment assembly)
• 🏭 Industrial assembly lines (large-scale fastening tasks)

The battery is the heart of an impact wrench. It determines the instant torque, working duration, reliability, and safety of the tool.

⚡ Technical Challenges of Impact Wrench Batteries

• High Discharge Current: Instant demand often exceeds 20–40A. Standard cells may overheat or suffer voltage drop.
• Long Endurance & Fast Charging: Professionals require continuous, all-day operation with minimal downtime.
• Safety & Durability: Tools operate in dusty, high-temperature, vibration-prone environments, requiring robust protection systems.
• Lightweight & Compatibility: Batteries must be compact and ergonomic, fitting slide-in or snap-on housings.
