YD3563 Battery Internal Resistance TesterDetailed product description：

The YD3563 series battery internal resistance tester is a measuring instrument designed specifically for new energy lithium battery packs. It can simultaneously measure the internal resistance (AC-IR) and open circuit voltage (OCV) of the battery, effectively evaluating its performance and safety. This series of equipment has fast and highly repeatable measurement capabilities, making it particularly suitable for in/out inspection of battery cells and battery modules.
