Decent price if you don't need POA. Seems to be 8800mAh too.

Surely here is an electrical engineer on mybroadband, why don't we build out own, improved version of the ratel, with double the batteries (at 80 bucks a cell it's not expensive).

If you are an electrical engineer, pm me maybe I can buy the schematics off you and then I'll do the rest (source, build, design the body, manufacture the pcbs etc)

What improvements would you like to make?
You could start with an off-the-shelf Ratel and add more batteries.

It might be too expensive to manufacture the PCBs and assemble here.

This person started thinking along the same lines:

absolutely crazy what people will spend on the same parts sold by communica wrapped in a nice plastic box

but i hope it works for everyone, working from home needs reliable internet

...but concluded the Ratel was actually good value for money:

I bought a 430M and disassembled it. I see the cells they use are 0817's so I'm adding another bank of them. I take back what I said; they're more than just a few off the shelf parts. Very good value for money, and easy battery change without a warranty sticker being voided.

I'm thinking 2 more banks of four cells each since cells are like R79 + enclosure R30

NO!

The 8100 has a maximum output of 100W, but it has 8x 1800mAh batteries.
Where as the 860P has a maximum output of 60W, but has 8x 2200mAh batteries. So if you are just powering your routers it will keep them powered for longer.
Furthermore the 860P does has POE.

Okay! And the 430M? I only need to power the router and ONT for 2.5 hours at a time.

4x2200mAh batteries
4x 12V outputs
1x 9v/12v switchable output
1x 5V output
1x USB
30W max output

I see the 860p is not much more than what I can find the 430M for.

Now I can't find an extra cable!
