Router Battery Backup

1. Do you only have the one POE combiner/splitter? As in, you only have 1 x

and dont have another one on ther Rain router side that splits the single cabel into two? You only have a single LAN cable going into the Rain cpe router?

Yes, that is correct. Only one LAN cable that plugs into the Rain router.

2. When you say the LAN/DATA side what do you mean? Because the DATA ONLY side is NOT powered in any POE combiner/splitter that I have ever seen. In the image below, the blue cable is the DATA ONLY side of the POE injector, with the red cable being the POWER input. The green cable is the combined DATA+POWER [POE] powered side:
View attachment 1517701

My DATA only side of the POE injector, has power. That is my issue. My connections is as above. I am getting power on the blue cable though, which I should not get. The brown cable is the LAN cable that plugs into the Rain router.

Here is the schematic of the average POE combiner and splitter pair. Would I be correct that your setup is similar to the one above? So we can ignore the second half of the breakdown below.

As you can see NO router will be able to be powered from the 'modem/switch' cable below, as it is not connected to any power. Only the DATA+PWOER/POE side of the injector can power items.

We can ignore the above, my setup is not like this, I do not split the power.

3. So what is the issue? If the Rain router powers on using the one GREEN Lan cable only, the blue LAN cable should go do your dlink and everything should work.

Yes, in theory but it does not. If I plug the blue cable into a DLink router, the LAN/WAN light does not power on.

If it does not, the RAIN router is being underpowered.

Since I am only supplying 15v? I can try the 24v port on the Mini UPS but I am not scared I will blow the router.

What happens if you simply plug in the blue LAN cable into your laptop?

I have not tried this before. I would think the laptop would not pickup the LAN. Saying the cable is unplugged.

I think its the exact same unit as the Elecstor 100W which says it supplies 15W through the USBC

What do you get time wise ?

I get 6.5 hrs .. holding up a Calix router and a single AirTies node.

I don't have a ups at the moment, had a 450v power surge which melted my 30w cheap ups.
But I did previously have a Ratel 860p which inexplicably died after a year and a half, that used to last about 5.5 hours powering a Mikrotik router, fibre ONT and raspberry pi

I just got one of these. Good price, considering what it goes for elsewhere (Takealot +40% and Geewiz +14%).

Datasheet: http://archive.communica.co.za/Content/Catalog/Documents/D1508710926.pdf

(Same price at Communica btw.)

I did a full cycle on it:



It ran just over 5 hours at ~ 18 W. I got the rated 7 Ah / 89.6 Wh within about +/- 3 Wh. Very happy with that.

I also inadvertently tested the BMS short-circuit protection. As with LVCO it just goes to ~0.7 V and then recovers when put back on charge. I'm not entirely sure how the reset/reconnect is implemented, but it worked without hassle.

My main concern with these drop-in LFPs is the potential for the BMS to be the weak link, especially in e.g. hot conditions with nasty motor loads, etc.

We'll see - has anyone had these in service longer than a year yet?

Fitted the 2 Netogy inline UPSs for the 8 cameras, now just the switch and DVR on the Netogy mini UPS. Will have to wait for next 4.5 hour slot tomorrow afternoon to see how it handles it.

So my DVR was draining the Netogy mini UPS before 4.5 hours LS sessions ended (could do about 3.5 hours) . I then put in a normal old school UPS with LFP battery before the Netogy mini UPS, and now that lasts over an hour (have not timed its full runtime yet) before the Netogy mini UPS has to start working

Good evening everyone. Has anyone ordered of a shopify store called eurogrid.co.za. There prices seems n little to good to be true. I am just curious if anyone has gotten there orders or is this another scam site. There portable power stations and generators prices are really good and i am hoping that it is legit. Any help would be much appreciated. Thank in advance

 

[x7razor]

lol my cousin also wanted to buy from them. No reviews no address only a cell number and prices is like crazy low that is a clue already for me i would stay away.

Thank you. I was also like whoa this is like crazy good prices and then started checking for reviews of the site and also for contact details. They are pretty high up on google searches. Well i hope if anyone does buy, they let us know if it went okay.

Hey everyone, the last time I posted in this thread was back in 2021 asking about boosting 12V to 19V to power an Asus router. At the time I was able to solder together a boost converter that worked, but I was always scared that it might burn up and damage my really expensive Asus router. So I replaced the UltraLAN unit I was using with a Netogy UPS100 Plus since it has a 19V5A port and even 5V for my VoIP's base station. The only downside is its battery capacity of only 14400mAh; for 2-hour load shedding periods it lasts, but anything longer than that and I get maybe an extra hour out of it max.

So I am just wondering if there are any new UPS units that have come out which have a 19V3A port and more than 14400mAh of battery?

Can you not plug the ultralan into the netogy?

POE Power is always connected to Rain router.

When I plug the LAN/DATA side of the POE Injector in a router that does not accept POE, the link stays down.
I do not get a IP, even if I use DHCP, link light does not come on, router shows the port is down.

If I plug a POE enabled router in on the LAN/DATA side of the POE Injector, the router starts up, so it is getting power from the LAN/DATA side of the POE Injector.

This is the only Gigabit POE Injector I have, perhaps I must just test with another POE Injector.

Did you paste pictures ?

I may be confused here... are you using an injector and a POE router ?
Possibly this is the issue, I don't know if the injector will use the same scheme as a POE device.

I use an injector like this:

and don't use a POE device.

EDIT: I had issues with using this over distance, I wouldn't get power if it was too long... or would get power but it would drop.

you could probably upgrade the batteries in the unit.
My guess would be it now has 6 x 2400mAh 18650 batteries (6x2400=14400)
If you replaced with 3000mAh batteries, you would get 18000mAh, i.e. 25% more backup

Did you paste pictures ?

Yes, I did, please check my posts above.

I am powering the Rain router via POE and use a standard router that does not have POE.

I've not used any of them although have used the Vizia 150W mini inverter. That outputs AC and have used that.
I suppose go on the best rated device with highest Wh rating and connector which fits the Lenovo?

If you want longetivity (eg 3000+ recharge cycles) I'd go with an LFP model and then you must either choose Bluetti or Ecoflow River 2, but these cost R6K and up.

Thanks, the person who asked me isn't going to want to spend more than 2.5k or so.

Most cost effective to just buy a spare battery for the laptop itself, assuming it's removable.
