Router Battery Backup

SubtleBeast said:
Purchased two "knock-off" Ultralans in Nov '21 and both have powered my Huawei B618 for 4-hour loadshedding slots with spare capacity left.

Both are still in use, but the usable capacity are somewhat diminished.
One powers ONT + Huawei router, but doesn't last for 2 hours, while the other one easily powers a ZTE LTE router for 2 hours+

Your Ultralan is probably from a bad batch.

Had mine since the end of '22. Using it to power my USB fan now and it'll last even a 4h LS stint so it's still getting used.
 
Need some advice please.

Recently received a faulty unit that "popped" while driving an ONT+router.
Batteries are shot too, although I could salvage one.

Upon opening I discovered two blown caps, 16V1000uF which I'll replace with 25V ones.

It's a 10000mAh, but can't confirm as the cells do not have any markings on.

Now, I want to replace those with 3000+ ones.

The question is, will the BMS (built-in to cct board) be able to handle the larger capacity?

They're connected in a 2S2P config.
 
The BMS will still work fine. It uses voltages to manage the cells for OVP,UVP

Replace them with any capacity you want bigger capacity cells will give you longer runtime.
 
I'm looking to buy a mini UPS to power my Fibre router. I am with metrofibre and have a Calix Giga center 844G-2, which is a combination ONT and Router, so I only require a single connection to the mini UPS. My problem being, I need to match the correct voltage between the mini UPS to the router, and for the life of me I cannot confirm the voltage of the router. I did not receive a manual with the router, and the voltage is not displayed on the box, the router or even the plug.

Does anyone have any advise?

So just to confirm, there's no info written on the power supply at all (eg, like on this one)?

Could you show us what the power plug (on the router side) looks like?

I think we touched on this plug in this thread: https://mybroadband.co.za/forum/threads/ups-not-compatible-with-frogfoot-ont.1195930/post-29653274
 
I received my Gizzu mini UPS today, and have a couple of questions:

1. How long does it take to charge from completely dead to 100%?
2. How does one know when it is fully charged?

I would assume it is fully charged when no lights are blinking? I plugged it in to test it quickly, so that I can return it if it's faulty, when I plugged it in the fourth (100%) indicator light started blinking, and when it stopped blinking, I assumed it was fully charged. When I plugged my router in, the 100% indicator light went off, which led me to believe it wasn't fully charged?

3. It is my understanding that you leave it plugged in permanently, after all that is what the "U" in UPS stands for, I guess - but just want to double check if that is the correct way to use it?

The model I have is the 30W 38Wh 10400mAh

Yes.

Plug it in.
Switch it on.
Plug in your router.
Go to bed.

I have one of these and have had it operate on load for longer than 5 hours on my router (Mikrotik) without dropping off, so yours should be similar. Been running for more than a year.

I connected my 12v 1a ont to by gizzu and it (ont) started smoking :/

as wingnut said or a voltage difference normally they will accept a bit higher than specified without popping
sure most are designed with a safety margin how big is like the piece of string who knows
