Router Battery Backup

Wasn't so sure about it but thanks.

No problem. I quickly checked, there seems to be a limit of 24W/2A on the 12V DC output port - just be careful that you do not go over that limit when you add up the load of devices you are powering.

Good thing I checked this before leaving the office. I think I might be over on the wattage by a whisker. So I'm going to have to get another DC cable.

Excuse my ignorance... how is another DC cable going to solve the issue? Mind sharing a picture of the 430M's output ports?

According to the guys at sinetech you can pull the full 30w over a single port as the ports are all connected within the casing in any case.
 
Hoping someone can shed some light, please:

Our alarm has two power packs (brand: Peak Power model TR6-HT_S042) each with an IDS 8Ah Gel battery in it, installed about 8 months ago. These are only used to power the external sensors (the rest is powered off the panel's own 8ah battery). Tonight they failed after 1 hour.

Instead of just replacing the batteries with the same I thought I should get bigger batteries but when I calculated the current draw to see what to get I do not understand how the current battery size isn't more than ample:

I traced which sensors are connected to which pack and looked up the manufacturer's (optex) spec for each one for current draw (@ 12VDC). I get to 58mA (1 x BX80 @ 38 mA + 1 x VXI-ST @ 20mA) on pack 1 and 77 mA (3 x VX + 1 x FIT-AT @ 17mA) on pack 2.

Since they were installed the longest outage I can remember (transformer fault) wasnt longer than 8 hours.

Even if you say 12 hours, there is no way that load would drain the batteries beyond 50% to damage them.

So now I'm stumped...

Before these packs were installed, all the external sensors were on a single pack (one of those Sherlo, assume 7Ah battery) which eventually couldn't handle the LS anymore and installer replaced with these two.

Anyone with experience with similar setup? Either the current draw actually much much higher than Optex says or these batteries or power packs are a load of rubbish.

I want to put in something that will actually last. Maybe I should switch to one of those Ratel 430m?

Thanks.

Not going to make a difference. But it isn't going to work in any case as the cables supplied do not fit the router. So looks like I'm going to have to hunt down a cable that goes from a thicker male(from UPS) connector to a thinner male connector (Router).

Bro we still confused...
 
Hi guys... I have a Tenda AC6 fibre router and the normal fibre ONT ... will the Ratel 430m be able to power them sufficiently for the 2 hour load shedding schedule? Also, does it come with the correct power cables to power the 2 items? Im not familiar with these battery-type devices, so pardon my ignorance...

Thanks

You are not counting all the power requirements of the panel etc. as well as the "losses" in the conversion process from the 12V battery to the other voltages that the system uses. The wiring etc also have losses, especially at low DC voltages.

That said, 8Ah should be plenty for at least 4 hours.

Maybe the battery is just a dud. They do not like to be drained fully even a few times.

Just buy a bigger gell battery like an 18Ah. Its around R650.

Lead batteries only like to get 50% DoD before you do damage to them (that is decrease their capacity)

Just go to communica and replace them with normal sealed 7Ah ones (~R150), then connect two 7Ah batteries in parallel. If they dont fit in the panel box then extend the connections and put the batteries on the floor.

Gel or not makes no difference because it's the heat in the roof/cupboard of the panel that kills the batteries over time. We only managed to get 6 months out of the batteries gel or not. Running two in parallel and they last 2 years or so, and as a bonus are perfectly happy for 10 hours runtime.

Heck if you are concerned, just wire three of them in parallel. Or use an old car battery - it wont be efficient to charge on the power supply but who cares if it takes 10 days to charge when it will last you just as long without power
 
Thanks. The panel has its own battery which powers everything except the external sensors which are on the two packs.

Remembered that my multi meter can measure current so tonight I'm going to measure the actual current draw from each pack and go from there. Will post results.

Managed to get a Ratel 430M. It comes with one DC to DC connector cable, the only thing this is split one-into two. Is it possible to use this to power the fibre modem and the router in one 12v output?

Where did you get this? Most places are out of stock

Unfortunately not, it cannot power my Asus AC68U with a DC buck converter (set to 17v), which draws just over 2.125 Amps. The data sheet says the max is 2 Amps too. So I had to revert to my Sherlo setup for now. For those that are struggling with the ports, it is a weird size (a little bigger than a 2mm socket). I had cut the split connector they gave to power and do a join to make it work. The back of the 430m is attached IMG_20200211_090528.jpeg

You're trying to draw 36w from a 30w power source. You'll need the 860p for this to work.
