Battery powered freezer?

[BaconB]

Okay, so this is technically a new build, right? So by next summer, I need a portable freezer so I plan to put a freezer in a cargo bike and have a battery pack. 

Batterypack:

Powerbox 1000, 1000Wh, 230v

Freezer:

Basic chest freezer, 211kWh, 211Kwh/365 days

 

Calculations:

211Kwh/365 days=0,550Kwh a day

0,550Kwh a day*1000(to make it into Wh)=550Wh a day 

I calculate that I can run this freezer for about 2 days on the battery pack, am I wrong? Or is there something stopping me from doing this?

That's right with that average spec and it'll likely last that long or a bit more to maintain itself cold, but for example if you connected it to the pack without it already being cold, or if you throw in lots of warm stuff to cool it'll likely go down in a few hours.

That should be good then, my plan is to connect it to a wall socket at night so its always cool.
