Aundhegrtt As Shown T469 Internal Resistance Tester Dc 5V 4-Wire 18650 Battery Voltage Meter Detector For Lithium Battery Detection
Aundhegrtt
The instrument adopts an AC 4-wire measurement structure to accurately test very low internal resistance values. This significantly improves measurement accuracy compared with traditional 2-wire testers and helps you quickly identify aging or poor-quality cells. This high- T469 DC 5V internal resistance tester is specially designed for 18650 and other lithium batteries. Using a professional 4-wire (Kelvin) measurement method, it effectively reduces line loss and ensures accurate measurement of internal resistance and voltage, ideal for battery screening, maintenance, and quality control. Optimized for 18650 lithium batteries, the tester can also be used with a wide range of cylindrical and pouch lithium cells within its voltage range. It measures both internal resistance and voltage in real time, making it suitable for DIY battery packs, electric tools, e-bikes, power and more. Built-in wireless communication allows you to connect to a dedicated mobile APP. View internal resistance, voltage and status remotely, record and analyze battery performance without standing next to the device, improving testing efficiency and safety. Powered by a standard DC 5V source, the tester is convenient to use with USB adapters, power or common 5V power modules. Stable low-voltage power input helps reliable measurement results while maintaining low consumption., Manufacturer: Aundhegrtt
