Not suitable for: large trucks, cranes, forklifts and other high-power and high-load vehicles! 12-60V meter universal: 12V, 24V, 36V, 48v, 60V, (not compatible with 72V) 12-72V meter universal: 12V, 24V, 36V, 48v, 72V (not compatible with 60V, 84V) 12-84V meter universal: 12V, 24V, 36V, 48v, 60V, 84V (not compatible with 72V) This fuel gauge is suitable for 12V, 24V, 36V, 48V, 60V, 72V, battery cars (common for batteries below 96V), and can also measure lithium batteries, polymer batteries, and nickel-metal hydride batteries. It can also be used for other power/voltage measurement purposes. Double display battery + voltage at a glance. The display is more intuitive. The upper 8 bars show the battery power (2 red and 6 green). Downlink voltmeter (display battery voltage), voltmeter decimal point automatic shift accuracy is higher. It has a wide range of applications, including lithium battery packs, lead-acid batteries, car batteries, electric car batteries, and many other types of batteries and electric equipment. The calculation of the existing voltage is the same as that of the power display meter of an electric vehicle. The meter head automatically recognizes the voltage and electricity, and has a reverse connection protection function (reverse connection will not burn). Instructions for use: The two-wire system of the meter head can directly test the battery. Parameter: Voltage tolerance: 1-2%; 8 levels of power: 10% 25% 40% 50% 60% 75% 90% 100%full Working current: 5-15 ma Refresh speed: 300mS once Display mode: three-digit 0.56" LED digital tube Voltage color: red, blue Lead length: about 20cm Dimensions: 48 x 29 x 22 mm, length X width X thickness; Mounting hole: 46 x 27 mm Working temperature: -20~65 Application range: 6V 12V 24V 36V 48V 60V 72V lead-acid battery. Suitable for 36V, 48V, 60V lithium batteries Lithium batteries, polymer batteries, nickel-metal hydride batteries, lead-acid batteries. Cars, motorcycles, bicycles, trucks, etc. The Sun can generate system Product support customization: If you need other voltage (such as 30V, 25V, 21V, 16.8V, etc.) lithium batteries, please contact us, thank you.
