High Fast YR1035 Lithium Battery Internal Resistance Test Instrument 100V Electric Vehicle Group 18650 Tester

True 4-wire AC sinusoidal measurements effectively avoid the effects of test leads and contact resistance. Two function interfaces, battery sorting function. Built-in battery, Android phone charger charging, low power consumption + multiple power saving options. The test range is up to 200 ohms with a minimum resolution of 0.01 milliohms and less than 5 milliohms. HOLD to enable the ZR function to measure internal resistance as low as 0.30-0.50 milliohms. Handmade, the appearance of the right side is overly cautious. high-voltage battery internal resistance tester. True four-wire 1Khz AC sinusoidal battery internal resistance meter 0.00001 ohms --- 200 range. It can measure lead acid, lithium ion, lithium polymer, lithium iron phosphate, alkaline, dry battery, hydrogen, , button battery, etc.
