Unregulated series & parallel steup?

[Lorenzod123]

Hey guys, I got a really random idea and wanted your opinions on the feasibility.

Basically, I want to use two battery sleds with 4 batteries where all the batteries are in parallel so 4.2V and 40-50 amps each, then attach both sleds in series for a total of 8V and 40A. What are your thoughts?

Something along these lines

So what are you planning to blow up? Must be big.
