Hello everyone, I'm making a home made speaker that uses a 3.7V 3500mAh battery with a boost up to 5V and I want to see the capacity remaining on my battery. I fuond this voltmeter but I don't know if it will work. I'll connect it to the battery, not the 5V booster. If there is one if Leds or saying 10%-100% left I would really like more. Thank you in advance
