Thursday night I was out using the scope, and put the battery packs on charge afterwards.
The power tank I use on the mount was recharged before I finished processing my spectra and went inside, so I unplugged it.
Friday morning, I went out the obs to check the jump starter pack I use for the dew heaters. Strange... still charging. I let it go, came back later that afternoon... still charging. That's a bit odd, but left it go...
This morning I went out to check it again... What? No LEDs on at all

... oh... some idiot left the dew heaters plugged in!
I unplugged the dew heaters and at least the charging light came back on...

. Here's hoping the battery comes back up and hasn;t dropped a cell like my other jump starter pack did.
The frustrating part is I have a check list stuck to the inside to the obs door for me to check before I leave! Did I read it? NNNNOOOOOOO!
There's just no helping some people!
