@InspectorCaracal i'm dumb at engineering sciencey type shit but you could always go with the container running dry instead of the units in the container running dry - e.g. batteries are made up of cells, so "even if he drained every last [energy] cell"
that might mean the audience also stays with you a bit better instead of going "wait, volts? do you measure batteries in volts? is that right? i think it's volts..." ......possibly?
@wigglytuffitout also, most people when reading who aren't actually in electrical engineering would just recognize that it is talking about electricity and move on, I think.
@InspectorCaracal ahh yeah i see now, you've got that detail working for you
well i know it's probably either volts or amps and beyond that i'm clueless i'm afraid LOL
@wigglytuffitout that's exactly where I was XD XD fortunately Octo-Sam helped so I can keep writing instead of getting stuck on a stupid wording issue lol
@wigglytuffitout I considered that but my protagonist and PoV is a computer and using the right units seems like an important point of establishing character <.<
