I just purchased a Drok VAC9010H and have it hooked with the POS cable through the Hall sensor. I have a 300AH lithium battery. charged to 13.6 after one day it was down to 31.1. I also have solar but it goes direct to the battery. So my solar put in to the battery 137 AH but the Drok did not have any value in the AH  screen. The volts and amps show value. I should show AH used during the day. At the very least I should show 137 AH used.

Do you have a better manual or more complete user manual for this unit?
