I have a problem with drok energy monitors we use in our caravans. After discharging the battery the AH remaining and capacity percentage reduce and it all seems ok but as soon as you connect and start charging the unit the capacity and AH remaining immediately jump to 100% and full AH capacity which cannot be the case as it would have to progressively increase with the increase in current input. Thus the energy monitors are not effective at measuring the state of charge of the battery. Please can someone help I have a video of this issue.
