Battery backup

[lost66]

Thanks everyone for the input. I didn't take pictures and honestly it is quite messy and the place where I place the batteries is a spaghetti mess.
I tested the system and for fully charged batteries my powerhead was running for around 90 hours. It is like 10 seconds flow and 10 seconds pause so let's say around 45 hours of constant run. If I add return pump I may have ~20 hours of power backup.

Fwiw, and since I asked earlier if the Icecap v2 was available anywhere, Champion Lighting has the "Coralbox Aquarium Pump Extender v2" in stock. Mine was delivered today and I'm charging it now. As far as I can tell, this is the same as the Icecap v2, so should work for the 24v pumps.

I have a feeling this summer and hurricane season will bring some surprises and I think it is time to secure reef life support - I need battery backup. I don't want to power everything, I just need 1 power head to run let's say up to 24-48 hours. I am cheap and all my pumps are Jebao 24V. My power head consumes 10W.

There is out of the box solution for around $140 which is IceCap version 2 (https://www.championlighting.com/jebao-battery-back-up-system.html). First version of that battery was 12V, second one was 24V and third one is 12V again. For some reason they discontinued first and second versions leaving only 12V option. I don't know if buying discontinued product is a good idea. I don't even know how long that batter will last for my 10W pump - I have no idea how to calculate it.

So, going to DIY - what I can do is to buy 24v battery, charger and a battery automatic switch and everything should work. I mentioned I am cheap so I don't want to break the bank here with batteries but I also know a cheap battery is not a good idea. So, any hints what affordable battery I could use? Any links from Amazon?

My tank is located in kids room so I don't want toxic fumes from car batteries, etc. Do you think something compact from 18650 batteries would be ok? Like this

I weathered the snowpocalypse in Texas using my truck battery and an inverter. The problem with just a battery is time, how long can you hold out? In summer it is easier because you don't need heat, but winter you'll need a better solution.

Either way, you'll need an inverter and I would make sure it's a pure sine wave setup. I've had issues with modified sine wave with different items.

Yep, I'm in Houston, although we didn't actually get much snow here, lol. I think the spirit of this thread is an automatic battery so the power supply to a few pumps will stay on temporarily and until a longer term power source (inverter generator) can be started.

You can DIY a quick 24V battery backup using simple DIN mounted modules - all neatly mounted on a single DIN rail. These are high quality devices that are used in industrial environments.

Depending on how many devices you want to run pick your power supply.

or

then get a UPS module.

and pickup 2 x SLA batteries. Depending on your budget you can pick one of these or anything in between.

You'll also need some wires and DC breakers for safety.

To tie your devices to the unit, you can use of of these

They come in 6, 12 or 18 positions so you can connect whatever your heart desires.

With this setup you can dump all OEM power bricks and just power everything from the new unit you build.

Choose your power supply wisely to handle the load. There is also a module that will allow you to combine multiple power supplies if you need 20 or 40Amps or if you want to provide power from multiple circuits. You'd can run a lot of powerheads and pumps from one of these things.

Additionally, above setup can be connected to your APEX for monitoring via I/O ports.

LMK if you have questions.

Hi, do you have a diagram or picture of your system?, to have a better overview, thank you in advance.
