Router Battery Backup

Defiler said:
Anyone run 24v Ubiquiti devices connected directly to 2x 12v batteries? My Mikrotik router, switch, and ONT is connected to a single 12v 33Ah gel battery that gets charged via a 100w panel. I'm thinking of adding a second battery and another panel, so I can power my two tough switches at the other end of the house on 24v, however, I assume the voltage while charging will be over 27v, and the input voltage for the switches are 22-24v 2.5A...

What will be the best way to regulate the voltage from the batteries to 24v? I'm sure I could just wire in a fuse, resistor, and a zener diode to do the job?

Charge controller might even have a regulated output

How does that work? I love it when manufacturers recommend things but don't tell you the reasons why.

Maybe it discharges the battery while it's charging and doesn't bypass the way a UPS should, while the mains power is on?

Maybe, but if that's the case and it's charging and discharging at the same time then the battery isn't doing anything so how does that shorten its life?

It draws power from the battery while charging it? Won't that generate internal heat and cause unnecessary movement of ions which will reduce longetivity? So during this time the unit should be mains powered but instead powers battery which powers your kit, while mains AC is on.

On the Ellies Cube Nova on Geewiz...

I am pretty sure that the Geewiz description is because of the experience that I had. I bought the unit from Geewiz, tried to use it, followed all the instructions, but it kept inexplicably dying in the middle of the night. Eventually I setup a camera to catch when it died.

Geewiz were really good; they asked questions which I answered, reached out to the supplier, and the supplier provided feedback that it couldn't work as a UPS. They then advised that they had updated the site.

What is the recharge time on this Ellies Cube Nova?

I ended up getting the Ellies Cube Mini a few days ago. Nothing beats having Fibre in darkness. It served it's purpose twice.

Should keep my entire network and alarm CCTV running for 3-4 hours. Going the easy route, by just putting the plug into it. Don't care about the other ports. Apparently works like a UPS, so it powers everything downroute while it itself is being charge.

Let's hope it works.


Edit : now having caught up with the thread , hoping when it is being charged and providing power to downstream devices , that it is bypassing the batteries. Wonder how one would check that.

I have this too. The LEDs are very bright.

Give us some feedback when you have tested it.

This didn't make any sense. It is not possible for current to be following to and from the battery at the same time. It can be likened to a hosepipe. Water can't be following in both directions at the same time.

Either a power source is feeding the battery and the load at the same time, or the battery is feeding the load if there is no other power source.

In that case batteries in online UPS's must get smashed because they run off the battery all the time or maybe they don't? I would think as long as the charge current is more than the draw current then the battery will stay full. I'm just speculating as I'm no expert, just thinking out loud.
 
I was using the Huawei B315 with Huawei battery - that thing lasts more than 4 hours.

Just got fibre - the Huawei B315 has the same power connection as the Mikrotik Hap AC2 they supplied, but the Frogfoot ONT takes a different power input.

Which battery similar to the Huawei would work on the ONT?

If some battery cells are being charged while others discharged constantly while the mains is on, isn't that a waste?

So these "power station" units are designed like power banks and not UPSes.

But do they? Don't they run through some sort of switch with a capacitor which shifts the power source from mains to battery when mains fails?

It doesn't help to speculate if you don't have the background. What you are asking is not possible.
 
My initial thoughts on the SolarWize mini-UPS and customer service:
  • I ordered the unit on Tuesday (02 Nov) and made payment in the afternoon.
  • The unit was delivered earlier today (05 Nov) by courier
  • I was kept updated by Dante throughout the process
  • The reason I ordered the unit was primarily for my Asus router which takes a 19V input. So far, so good.
