Good Afternoon, I was at the "Paws in the Park" show in Kent this past weekend with no EHU. I am a bit concerned about how my battery bank performed. I have dual Banner batteries totaling 200A, both are less than 2 years old. I also have a 100W Solar panel to help charging. The batteries were fully charged when I arrived. Over a 24 hour period the most power I believe I could have consumed was about 7Amps for 5 hours. However the batteries were reading 12.4V which I believe it about 50%, there was thick fog over this period so I don't think the solar panel was contributing much if anything at all. I woke up the next morning at 8AM and once again checked the batteries they read 12.9V which is 100% full I think. Now it was a very sunny morning however it had only been daylight for a couple of hours. I am confused on two fronts. 1) Why did my batteries drop so quickly? 2) How did they charge so quickly? The battery readings were taken from the solar controller and checked by a meter reading directly from the batteries. Any ideas would be much appreciated.
