Sinyiin Intelligent Lithiums Diagnostic Equipment 8-Channel Thermals Management System — 8x 18650, ± 1% Accuracy

Designed for rapid batch testing, this Sinyiin unit inspects 8 separate 18650 cells at once, delivering a measurement accuracy of ± 1% to greatly speed up battery evaluation compared with single-cell testing. It is targeted at battery manufacturers and maintenance technicians who need quick status checks for multiple cells. The built-in internal resistance detection function measures from 0.1mΩ to 10Ω, allowing precise assessment of battery health and early identification of faults to help prevent equipment damage from battery failure—especially useful for electric vehicles and energy storage systems. A high-definition LCD provides real-time readouts of cell voltages, capacity and internal resistance for easy monitoring. The device also includes onboard storage that can save up to 100 set of detection data for convenient historical review. Compatible across a range of uses—electric vehicles, battery packs, residential systems and more—it can increase compatibility by up to 30% and is well suited for maintenance, performance evaluation and scientific research testing.
