I've got one of these battery backup units I was going to use for power outage aquarium power, I found that I end up using my gas genset anyway for power to some lights, fridge etc. and used it to look after my aquarium as well.
Long story short I don't need it now, when I got it I was told it needs new batteries. If you are interested and know anything about these things I'm willing to sell it "cheap", or trade for corals. PM me if your interested.
