The flaw detector is a portable industrial non-destructive flaw detection instrument, which can quickly, conveniently, non-destructively and accurately detect, locate, evaluate and diagnose various defects (welds, cracks, inclusions, folds, pores, sand holes, etc.) inside the workpiece , can be used both in the laboratory and on the engineering site. The instrument can be widely used in manufacturing, iron and steel metallurgy, metal processing, chemical industry and other fields that require defect detection and quality control. Life assessment, which is a must for the non-destructive testing industry. Portable flaw detectors have become an important tool for on-site testing in modern society, and providing efficient, portable, light, and sufficient backup power solutions for portable flaw detectors is an important guarantee for testers to carry out long-term on-site work. Because of its own unique advantages, 18650 lithium battery pack has become the first choice for the backup power solution of such high-tech testing instruments.

  The lithium battery of ultrasonic flaw detector is a 14.8V lithium battery pack made of a single 18650 battery cell combined with 4 strings and 2 parallels and then packaged with green plastic. After long-term experimental application, this aluminum shell lithium battery represents the portable lithium battery advanced level.

  So how do we choose the ultrasonic flaw detector battery? Here I recommend TEFOO ENERGY‘s smart lithium battery pack, which is convenient and simple and has passed multiple certifications, so you can use it with confidence.
