Any electricians in the house?

I was wondering if it is possible to just use my existing UPS backup system (designed for computers) except I would disconnect the wires going to the little UPS battery (12v) and hook them up directly to the battery in the Motormaster Eliminator.

Basically I am just utilizing a larger battery for my UPS and bypassing all the inverter & charging systems built into the Eliminator power box.

Could just go out to Cdn Tire and buy the biggest RV battery out there and hook it up in parallel to the existing UPS battery (assuming 12v) than gut the Eliminator. The only caution would be the charging circuit on the UPS could be taxed once utility resumed and if the battery was significantly discharged. Could get around it by charging the larger battery separately.

I would just try the UPS you have now on a test to see how long the battery would run the powerhead.......and if its sufficient...use it...if not...spend $100 and get a bigger one....

I already have the Eliminator, I bought it when it was on sale. I have plenty of other uses for it aside from the fish tank should I end up going another route. I was hoping I could just wire it into my UPS and save having to build a seperate relay box.

The battery in my UPS is dead, won't take a charge anymore.

To make this plug 'N' play or easy , go back to Canadian Tire and buy the Noma 400 battery back up system, it has the relay already build in, just plug it in the wall, plug the power head in to the Noma and your done! The power head runs all the time, power outage or not. The Noma costs $199.00, Canadian Tire has them on sale often for $140.00 or so? Just watch the flyer
It can also be done with two relays with what you have but that's another story and the Noma is SO much easier
Just my 2 cents...

Not a bad idea, however I have other uses for the Eliminator and it's 1200 watts compared to the Noma which is only 400. I have 4 tanks to maintain during power outages.

I am planning on running one air pump that will supply air to a single air stone placed in 3/4 tanks, the 4th tank will have one powerhead running instead of a airstone.
