The batteries are all within 3% of the expected weight. Seems good enough for me.

I gave some thought as to how to distribute those 16x batteries within the UPS (4x) and the external battery unit (12x).

In the following, I'm omitting the 5lb part of the weight and mention only the ounces.

Not that I think it will make much difference, but I'll put all the four equal batteries into the UPS (4x 10oz batteries).

That will leave the following for the external pack:
'
* 2 x 11
* 1 x 10
* 7 x 9 
* 2 x 8

The other choice I'd make: put 2 x 11 and 2 x 10 in the UPS, leaving the external battery
unit with:

* 3 x 10
* 7 x 9 
* 2 x 8

I don't know enough to know if this matters and I expect I'm merely overthinking this.
