eBike/Universal Voltmeter and Ammeter

Unless you have a smart charger for your eBike, it's hard to know when the battery is charged.
This is a small Voltmeter/Ammeter, designed to go between battery and charger to tell the voltage and amps being delivered.

It can also be used in between battery and motor/controller to show remaining charge. Although I havent designed any mounts for it to go on the bike

Can be used in any project where measuring 30-100V is needed up to 3A

Based on simple $3 Voltage Current indicators from china, 2x 18650 cells and a small charging circuit. A switch and any connectors you like/need.
