0.1uΩ-3.1kΩ AC Four-Terminal Battery Internal Resistance Test Product Overview This equipment uses a 1kHz AC constant current source and a four-terminal method to measure the AC internal resistance (ACIR) and open-circuit voltage (OCV) of lithium batteries. It boasts an AC impedance resolution as low as 0.1uΩ and excellent anti-interference capabilities. This equipment is widely used in processes such as cell formation and capacity testing, battery screening for modules/packs
