I had the battery fully charged to 52.6 volts, so I thought I would do the test again.
(I had to reset the timer and the voltage dropped to 52.5 before I could take the picture.)

Left the power on and let it sit for 10 minutes,..

Shut it off for fifteen more minutes then turned it back on,..

After 43 minutes the voltage was down to 52.2 volts.

And a complete recovery two hours later..

So my results are inconclusive.
I did lose 0.5 volts starting from 54.6 volts, and 0.4 volts starting from 52.6 volts though.
But it's all kind of erroneous.
Maybe I'll I'll install my Watt Hour Meter this winter so I can monitor my batteries more accurately?
I'm sure that there's nothing wrong with my batteries. They all behave the same way.
I guess it would be good to test the capacity of the batteries. The biggest batteries (physical size) are 19ah and 25ah, but the smallest battery (Das-Kit) is supposed to be 21ah.
I dunno? That doesn't seem right?
