    Thanks - it looks interesting. Presume the battery would last for around 3 hours load shedding?

    I would go with one of these from the source you found... https://www.alarmtec.co.za/battery-c...-c-53_186.html There is a box/charger for a 7AH and an 18AH battery backup. The smaller one will do it, but I would go one size up to be safe.

    Original reply in post #120 and you will see that was a better deal.

    Post #122 is my setup with the 6.4A unit. Fiber, Router, Airtie Mesh Wifi, Raspberry Pi servers x2. Longest I went and still had battery left is a little over 5 hours.

    Sawyer Security is better priced.

    I used the cables that came with the devices, cut off the power supplies (left some cable for joining if ever needed). DC-DC for the router was moded inline and heat shrink wrapped.

    Voltage on battery after 2 hours loadshedding is @ 12.6V, so plenty left for longer outages.

    Currently using of an old deep cycle for the ONT and 2 regulators for the router and voip base. But its too bulky.
    This looks like a great idea, especially the added usb ports.

    @MThompson
    Just looking at the photo I assume you have to run the USB regulator direct of the battery then? (looks like the rest is run of the supplies on the board)
    Yes, yes, too lazy to look for and download the manual

    Only for the one, the POE access point, the only reason I have 3 is because of my network layout at home that was done many years ago so I was forced to get 3 of these.

    The plus point is your can run each device for longer during any extended power failures.

    1 x DC output Cable with 2 ends.
    The DC output cable plugs into the UPS and the other end into your router. The 2nd DC socket on some UPS is the input from the 220V charger. The larger DC plug goes into the UPS. One cannot connect the wrong plug into the wrong socket.

    Currently my best solution would be 4 x6Ah lithiums R260. 10A BMS R210. China 12V 5A power supply R250. DC sockets and plugs to suit and an enclosure to house the items. This can be good for 5 - 10 hours for a single router.

    Not directly linked to your reply but what do those Chinese mall 12V battery chargers look like again, the ones you recommending in the offgrid thread I think it was, do they have a make or model number?

    I want to get one to leave in the car in case I flatten my battery somwhere.

    This is the only picture I have at the moment. They come in a blue box and it just mentions Pulse Intelligent Charger. 12V 7A. Some boxes are wrongly printed as 7Ah instead of 7A.

    Just ensure you don't buy the type in a orange or black coloured plastic box with a fan on the one end. The one in the picture as well as the one that I don't like with the fan are both GAmistar make.

    I can still supply as it is such a cheap unit and mine is now in daily use for over 3 years charging my outdoor lights 100Ah battery. I belief it is the best way to part with R200.

    Many thanks, so the one in the pic is one of the ones to avoid?

    No the one in the pic you can buy. It is the one without the fan.

    Just to confirm, this type of charger in theory should be safe to charge a vehicles battery in situ without disconnecting it?

    Not one of quite a lot reported any problems. It includes cars made in the last 3 years. Just connect on the battery 1st and then switch on the 220V AC
