I would like to add a voltmeter/ammeter to this mower.
It is a small panel type meter to check battery voltage and ampere charging.
It doesn’t have a factory ammeter installed.
0.28" LED Voltmeter Ammeter, Red Blue Digital Multimeter Display Voltage Current Tester, DC 0-100V 10A Detector Voltage Current Surface Panel Ampere Voltmeter
