That is weird, I have gotten up to four days off of the stock Panasonic battery in my FJ while running the fridge non stop one time.
A little hard to start the rig at that point, but it started.
No longer have that battery though, the FJ got a new battery earlier in the year, or last Christmas.
Now back to my Ark, it was just showing 100% charge, and in discharge mode, and 12.7V, and then right before my eyes dropped down to 12.6V.
Maybe mine is alright?
I did get the battery error message again a few hours ago, and instead of shutting down the LCD screen, I just pushed the info button and it went to the temperature screen, then after 20 seconds or so back to the normal screen.
Sure would like to know why I get these errors though.
And when in error mode, is it still charging?
Ed, you might look into getting the Goal Zero charge controller like I bought and a solar panel to keep yours charged up in the field when running the fridge.
I would think with one of these deep cycle batteries though you would get for to five straight days operating the fridge.
Did you have the LCD screen activated the whole time, or shut down.
Shutting it down will save some juice since the fan is always running when the LCD screen is on.
We are suppose to get some high winds tonight here, possibly up to 50 MPH, so when I wake up at 1 am tomorrow morning to get ready for work, the Ark may be called into duty to run some of those Goal Zero LED lanterns so I can see, that is if we lose power.
