So I got the battery hooked up a lithium 10a charger. Fully charged it to 100% via the app. I have turned on my units to see the voltage. And it said it was at 13.6 let it load the battery for like 5-10 minutes check the app and it said I had 1-2ah left of the battery. Multimeter on the battery said it was 13.7 volts. Any ideas why the app and Bluetooth is way off.
