Voltmeter For Ebike Batteries

Description

This handy voltmeter displays the actual voltage of your ebike battery from its charging port without turning on the battery. Ideal to check on the status of the battery before and after charging. It can help to identify if your charger is working properly. It displays voltage from 0 to 100V DC and requires a 9V alkaline battery (not included) as a power source. The 5.5mm x 2.1mm barrel jack fits most common ebike charging port. The voltmeter can measure voltage of any battery from either the charging or discharge port.
