DIY battery back up?

[ddaquaria]

as stated - the Vortech is 18AH for 30-36 hours at the low end of GPH, so 35AH would almost double that time.

Just need to figure out where to mount it internally so it will not look as cool as the Ecotech model, but forget cool if it going to cost less and offer more (and you don't need to see it anyway)

It's not that big, I plan to put my behind my stand and 2260.

But I got a big stand and don't know how much room you are working with.

[ddaquaria]

I hate electrical stuff being on the floor (bottom of the stand). As soon as I figure out what size it is, I'll see if I can get a shelf installed to sit it on.

Since you may be moving on this faster than I am, let me know where you plan to pick up some of this stuff and what brand you ended up buying.

fo sho,

I'm think about just getting what they posted on there via those links.

Should help short term for those that need the protection and don't got money for the vortech.

I just wanted to add here for those of you who don't much to spend or are looking for a last minute "quick fix". I bought 2 of these last year about 2 weeks before Ike hit. Along with it was a 24 pack of D batteries (Walmart, Costco, etc.) I wasn't at my apartment when the storm hit, but the good thing about these pumps is that they kick on once the power is cut off. Batteries lasted about 12-15 hours. I was without power for 15 days and these held up just fine.

Anyway, just my .02 cents, cheap alternative if you don't have time/money to rig up one of these DIY kits. Would be nice however.

I think I found the exact battery that Ecotech may be using: http://www.power-sonic.com/index.php?id=31&gr_id=40 The dimensions fit within the given specs (and it just makes sense)

Mickey, please call me. We need to talk...john

Mikey, I think you'll be hard press to get one battery to run both those canisters for that long. All you really need is a converter. When lights go out plug up the canister to your car battery. Thats cheap and it gets the job done.

Only certain applications will need the power to stay on continously, i.e., reef tanks.

Bump,

Does anyone here have a true battery back up that stays on 100% of the time and switches over to the battery power when lights are out?

[jessicameyer]

I used a 2000w power inverter and an 18v truck battery for my battery backup.Any more ideas?

Do you have a relay on it?

What do you run on the battery and how long does it last?

[manoba123]

DD, Try it and report back on how long it last. Glen was going to try the same thing but never did it, I don't think. I would love to get a second person to try a UPS and see how it works. Again, as stated above it did not last long for my friend.

I have a apc 550 battery back up.and only have my fx5 hook up.when power goes out it kicks in for a hour .

Could you use a UPS to charge the deep cycle marine battery and as the switch when the power goes out?
Basicly route the system to use the deep cycle marine battery insted of the tiny battery that is in the UPS....
I THINK THAT WOULD WORK...
