i picked up the battery backup unit for the vortech pumps. pretty impressive unit. with a full charge it will run a pump for 30 hours at half speed. the driver in the pump will recognized the reduced power input and automatically reduce its speed to half speed. if you have your pump manually set below half speed it will stay there. this unit can power 2 pumps as well, i just have to buy the extra cable to hook it up. it is a little heavy so i'm going to have to try and figure out where to put it. initially i wanted to mount it on the top ceiling of my stand but i dont think the screws will hold it. the battery last for approximately 5 - 7 years and icecap will replace the battery at this time for a fraction of the cost which i thougt was pretty cool.
