2m 50A 12V 48V Digital Display DC Current Voltmeter Lead-Acid Lithium Battery Charge Meter

GY-K1S is a high-precision battery power display meter, which accurately displays the battery power percentage, capacity, current, and voltage by means of current calculation (coulomb counter).
The GY-K1S coulomb meter is not limited by the type of battery. It can be used on any battery with a battery voltage of 8-120V. It can accurately grasp the working status of the battery in time; especially for loads with large current fluctuations and intermittent work. The use of high-current loads is very effective, such as various electric vehicles, sweepers, electric forklifts, and equipment with high-power motors.
The power is displayed by liquid crystal, which is clearer and more power-saving
Applicable to any battery, battery pack or device, such as lead-acid battery, water battery,
Lithium batteries, lithium iron phosphate batteries, nickel-cadmium batteries, nickel-hydrogen batteries, etc.
Support capacity setting, support reset battery voltage value setting
Turn on and off the display manually, and automatically turn on and off the display when the current is detected
10 seconds delay automatic sleep function, can withstand ultra-wide voltage input
