They are made from 30 thin layers of copper bent in the middle an pressed òn the ends nickel plated. And insulated. But I would use bus cables an only use these flexible busbars as a last resort

its just to know why you use the 4010 if you have an 8 cell pack instead of the 408

Many things are 3kw here. Everything from the over in your kitchen, the dryer, the washing machine, the hairdryer is 1800 watts, the thing I used to bend the pipes in my PC is 3000 watts, my fan heater is 3000 watts. My power supplies are 2200 and 3000 too And theres literally 18 sockets in this bedroom!
You should be able to get 16A at 110 volts at least. Thats 1760 watts. And have double that at 220V for heavy appliances. At least in the US.
Here and most of the world 240V is at every socket. And 3.1kw capable.

I can't here if I'm not going to burn all the children of the town

Waiting to see bulging cells too.
Prismatic cells are much less pressure tolerant than cylindrical ones .
1C charging is hypothetical in laboratory.. Reality , or Aliexpress , never comes close.

Sometimes people doing my charging don't push the Anderson in all the way, but it had been working a long time before I realised they weren't pushing it all the way in. I guess if it's shoved in enough for the metal contacts to be pressed together it works. But I found some handles that help pulling them out, which helped encourage my helpers to plug them all the way in.

They also had little rubber covers / caps for the end in case dust or water might be a problem.

Looks like the F5 has the batteries side by side vs. the C500 divided end to end configuration. I guess if I get one made for the C500 I should configure the cells in two Group 24 sized groups which can be rotated to fit so I can switch it over to an F5 when the time comes.

One thing I have some concern about is centre of gravity. Looks like the cells are "about 4.12kg" so 8 would be about 33kg vs about 47kg for the MK Gels. With the extra weight of the standing feature up top, I'm not sure whether losing 14kg down below will make a noticeable difference to stability.

I've been using this Permobil C500 with standing for nearly 12 years so I'm used to it and F5 seems to be the closest thing. More detail in this old thread.

15mm thickness of roofing lead sheet in the bottom of the battery box will make up your lost weight and put it lower down for extra stability.
