2in1 DC 0-100V Voltmeter Ammeter With DC 100A 75mV Ampere Shunt Dual 0.28″ Red Blue Voltage Detector Current Indicator

2in1 DC 0-100V Voltmeter Ammeter With DC 100A 75mV Ampere Shunt Dual 0.28″ Red Blue Voltage Detector Current Indicator
This module uses two high-quality digital LED, high brightness, and can simultaneously display current and voltage.

This module uses imported MCU sampling and display current and voltage, and the software has a lot of data processing, the display precise and stable.

Features:
This module is a full-chip technology, exquisite workmanship, while ultra-small. This module has reverse polarity protection, even reversed, it will not damage the module.
50A and 100A range meter is accurate to 0.1A.
This mode can be used for monitoring the current and voltage of cars and electric bike batteries.
For other occasions where need to monitor the DC current.
Lead defined (5 lines):
Thin black line: header to the negative supply
Thin Red Line: header to power the positive (red line between fine and thin black line voltage is 4-30V, if exceeded will burn)
Thick red line: measure positive voltage input (the voltage between the thick red line the thick black line which is between the voltage meter display)
Thick yellow line: measure the current flow lead.
Thick black line: measuring current outflow lead (The thick black line and the thin black line are the common ground and communication)
