Are those batteries?
I´m doing research on personal submarines from "U-Boat Worx". I can´t figure out how do their Li-Ion pressure tolerant batteries actually look like (if you could find out that would be most helpful).
A separete company "Triton subs" have Li-Fe-P-O batteries which come in form of big green battery packs which is about the type of battery packaging I am familiar with. In case of U-Boat Worx I only stumbled across this image (see attachments). Could those be batteries? And if so why the packaging in souch a non space efficient way (to dissipate heat I could guess)? By the marking on the cables and cylindre I figured it could be manufactured by RS Germany which would fit although it would not be as "in-house" as U-Boat Worx claims it to be.
Anyway, thanks for any answer you can come up with,
