Router Battery Backup

Exactly where they are supposed to be! :cool:

My camera lens is dirty, so it might not be clear, but note that all my cables are all the same length, to conform to best practices. I also prop the UPS open like this to allow the small USB fan I use to allow better ventilation. Here is a better representation of the above:

i don't mean to be funny and i might be wrong but your cabling doesnt appear the same length or diameter?

R330.

This setup of mine is powering AC devices (fish tank equipment).

Have a DC-DC setup for the DC devices (routers, switches, CCTV, lights).

I have two of the same ups. How long does it take to get to 100% charge with the two batteries?

Forgot to add the sarcasm tag on my post. The diameter and length is supposed to be the same yes, but with such a small setup I doubt if it will be the end of the world. It was more a matter of that is what I had at the time and it simply had to do.

The plan is to get some standard cabling to improve the situation and neaten the setup with at least 1%. Where does one buy cables like that in any case?
 
From anyone who sells DC power equipment such as Communica and equivalent suppliers. Cables should be spec'd according to the maximum current expected on discharge and charge, whichever is the larger, +25%.
It is all about resistance, heat loss and volt drop. Positive and negative should always be exactly the same length, especially if batteries are placed in parallel with other batteries. Otherwise, the battery with the shortest cables will alwys get hammered to most.
 
Thanks to CoCt NGAF... Power off all day, I could test my 18ah battery on alarm + fibre cpe + 2x router + sip phone + pi Zero + a bit.

It dropped to 12.55v after 6 hours.. I think that means still more than 50% left.

Much better than I expected.
 
I got this for my Modem and access point.
Works well during load shedding....I get around 7.5hrs of backup
UPS 1
UPS 2
 
Hi guys,
What would you say would be the best solution for me to keep my Fibre router on during load shedding? I have a Nokia G-240W-C router which has the ONT built in from Vodacom Fibre.
The router has the following ratings: 12V DC 3A

I have seen these mini UPSs on TakeAlot UPS Multi-Voltage 5-12V & UPS 12V (2400mAh) (and it's bigger brother which I can't find since today on TakeAlot), the first one's output is rated at 1A and the second's is rated 2A but my router requires 3A.

Below are pictures of my router and power adapter.

EDIT: Looks like I should just wait for the Ratel 860P :unsure:
