I. Core Advantages: Two-Way Adjustment + Dual Lithium Batteries, Reconstructing Work Efficiency

1. Two-Way Torque Adjustment, Flexible Tightening to Adapt to Diverse Needs
The two-way dual lithium battery torque wrench breaks through the limitations of traditional single-direction operation. Clockwise tightening and counter-clockwise loosening can be switched with a single button. The torque adjustment range covers 50-1200 N·m (slight differences between models). It can handle the high-strength tightening of tire bolts in automotive repair, and also precisely adapt to the torque requirements of mechanical equipment assembly, construction scaffolding installation, etc., avoiding over-tightening that could damage parts or cause loosening.

2. Dual Lithium Battery System, Say Goodbye to Range Anxiety
Adopting a dual lithium battery parallel design, two core advantages are highlighted: First, doubled range, with a single battery capacity of 4.0Ah-6.0Ah. Alternating use of the two batteries can support 8 hours of continuous operation, meeting the needs of long-term outdoor construction; second, intelligent complementarity, when one battery is depleted, the other automatically and seamlessly takes over power, without the need for downtime for replacement, improving work continuity by more than 60%. Some high-end models are also equipped with fast charging technology, capable of charging to 80% in just 30 minutes, further reducing waiting time. II. Technical Highlights: Robust Configuration Builds a Performance Moat

1. Brushless Motor + Precision Transmission, Accurate and Stable Torque

Features a built-in high-performance brushless DC motor, which reduces energy consumption by 30% and extends lifespan by 2 times compared to traditional brushed motors. Combined with a planetary gear transmission structure, torque output error is controlled within ±3%, meeting industrial-grade precision standards. It also features a torque overload protection system that automatically stops the machine when the torque reaches a preset value, preventing equipment damage or safety accidents caused by over-tightening. 2. Intelligent Control + Ergonomic Design, Maximizing Ease of Use
Equipped with an LCD high-definition display screen, it shows real-time information such as remaining battery power, current torque gear, and working mode, making operation intuitive and convenient. The body is made of ABS engineering plastic and anti-slip rubber, with a weight controlled between 3.5-5kg, a balanced center of gravity, and less fatigue during long-term gripping. The trigger-type switch has a force feedback design, providing a comfortable pressing feel and precise control of the start-stop rhythm.
III. Typical Application Scenarios: Covering Multiple Industry Operation Needs

1. Automotive Repair and Maintenance
Suitable for tire removal and installation, engine bolt tightening, chassis component installation, etc., especially suitable for high-frequency operation scenarios such as repair shops and rescue teams. The dual lithium battery range can meet the maintenance needs of 30+ vehicles per day.
2. Industrial Machinery Equipment Installation
In the assembly and debugging of machine tools, motors, pumps, valves, and other equipment, it precisely controls bolt torque to ensure the stability of equipment operation. It is widely used in manufacturing workshops, engineering machinery after-sales service, and other fields. 3. Construction and Decoration Engineering: Used for scaffolding erection, steel structure connection, door and window installation, etc., efficiently completing high-strength bolt tightening, more than 10 times more efficient than manual wrenches, reducing labor costs.
4. Agricultural Machinery and Ship Repair: Designed for outdoor repair of agricultural machinery and ship equipment, featuring a dual lithium battery low-temperature resistant design (operates normally from -10℃ to 45℃), adaptable to complex environmental operating needs.
IV. Purchasing Guide: Choose high-performance products according to your needs
1. Key Parameters to Consider:

Torque Range: Select according to operational needs (50-800N・m for daily maintenance, 800-1200N・m for heavy equipment);
Battery Capacity: Prioritize dual 4.0Ah or higher capacity, fast charging support is preferred;
Accuracy Grade: ±3% accuracy for industrial applications, ±5% can be relaxed for home applications;
Additional Functions: Whether it includes torque memory, gear preset, LED work lights, and other practical functions. 2. Brand and After-Sales Service Recommendations
We recommend choosing well-known brands such as Bosch, Makita, and Dayi, as their product quality is more guaranteed and they offer nationwide warranty and convenient after-sales repair. For less mainstream brands, pay attention to the battery warranty period (prioritize products with a battery warranty of 1 year or more).
V. Usage and Maintenance Tips: Extending Service Life

1. Correct Usage Methods
Before operation, confirm that the torque setting matches the requirements, avoiding setting too high or too low;
When tightening bolts, keep the wrench and bolt coaxial to avoid tilting and torque errors;
When using two batteries alternately, avoid mixing batteries of different capacities or brands.

2. Daily Maintenance Points
Store batteries in a dry and ventilated environment, avoiding high temperatures, humidity, or severe impacts;
Clean the body and output shaft regularly and apply lubricant (every 3 months);
When not in use for a long period, fully charge the battery before storage, and recharge it every 3 months to prevent battery depletion and damage.
