● 18V/4000 mAh lithium battery wrench, using brushless motor, which saves 40% energy than brush motor, has higher working efficiency and longer service life;

● With reverse self-stop function, the maximum torque reaches 330 Nm, which is especially suitable for screw removal for external frame workers;

● Standard two batteries and one charger, using 4000 mAh high-capacity high-grade battery pack (charging time is about 120 minutes);

● The number of screw removal times of a single battery pack is more than 800 times; the body is short and compact (height 25CM, length 15CM), which is more suitable for narrow spaces, and the handle is small and easier to hold; the honeycomb battery pack structure is sturdy and resistant to falling, and each cell has independent protection, with better overvoltage, overcurrent, overtemperature, anti-short circuit, overcharge and discharge protection, and safer to use;

● The battery pack is designed with a higher and wider buckle, and the connection between the body and the battery is more stable. The connector between the body and the battery is designed to be extra long to avoid loose connection and poor contact;
