Voltmeter DC 0V-100V Digital LED 0.28 Inch Voltage Meter Power Volt Tester Detector for Auto Car with Red Blue Green Yellow

The product is great, I put 4 stars because the last part is not insulated, and it can make a short circuit, but that's how it worked, I recommend it

Small, bright: I put it on a homemade electric three-wheeler - it looks cool

Works well, from 4v and above, there is a regulator for adjusting the exact voltage

It arrived in 19 days📦 . It measures everything correctly, arrived intact, in good condition❤️.

I would like to see the connection diagram

Everything is fine .
