High-Accurate Fast Lithium Battery Internal Resistance Test Instrument 100V Electric Vehicle Group 18650

Features:
True 4-wire AC sinusoidal measurements effectively refrain the effects of test leads and contact resistance.
With two function interfaces, support battery sorting function.
Built-in battery, cellphone chargepal charging function, low power consumption and multiple power saving options.
Support tests up to 200 ohms with a minimum resolution of 0.01 milliohms and less than 5 milliohms.
Press HOLD to enable the ZR function to measure small internal resistance as low as 0.30-0.50 milliohms.
True four-wire 1KHz AC sinusoidal battery internal resistance meter 0.00001 ohms-200 ranges.
It can measure plumbic acid, lithium ion, lithium polymer, lithium iron phosphate, alkaline, nickel hydrogen, nickel cadmium, button battery, etc.
The ZR function measures below 5 ohms, and the internal resistance is more accurate.
