Can it make a 1.050ish beer 10 gallons? Enough to fill two corny after fermentation?
Make sure to read the posts and understand the perimeters of the method(s) addressed in that thread.^What about a higher gravity beer then diluting or topping it off in the fermenters?

Where do you brew?Yeah I think you're right on doing 2 batches. Good reason to get a 220v machine maybe.
We brew in the kitchen. I don’t have 220 there now but it’s directly below in the basement.Where do you brew?
Do you have easy access to a 240V supply, such as an electric dryer or car charger outlet?
If you only brew 10 gallon batches occasionally, instead of buying a whole new AIO brew machine, you can heat water or even boil wort using a "simpler" heating source, such as an induction plate or a bucket heater, or a 5500W element in a spare kettle.
I use a 240V, 3500W induction plate for brewing, I actually have 2 of them.
Although I can brew 10 gallon batches, I mostly brew 5 gallon batches, for more variety, such as using different hops, or a different malt bill. I do use a dedicated mash/lauter tun, not BIAB.
Heating 2 or 3 large kitchen pots on the stove at the same time will significantly speed up getting that 2nd batch going. With some keen timing that water can be ready for mashing your 2nd batch as soon as the wort from the 1st batch has chilled and transferred to the fermenter.I like the idea of heating up the water on the stove to save time on a double batch.
