Your question: "how do you ensure a solid heat resistant connecton with the cell terminals?" is unclear.
Couldn't you just do your best to try to actually **answer** the question?
Both physically solid and low heat at the connection are required, very much go together.
Ideally vibration / shock resistance are rated with standardized tests.
A connection getting intermittently loose creates high resistance, in the wrong situation / location could easily melt any plastic or even start a fire.
So, more specifically, what exactly is maintaining a constantly strong connection to / between the cells as they rattle and roll maybe get into a crash etc?
What is joining the cathode / anode ends to the connecting wires / strips / plates / springs?
If no substance like a conductive adhesive, just friction, then what X is providing the force / pressure, and how much?
Does that pressure reduce over time as X weakens with age, or shock / vibration take their toll?
Is there a spring in there? If foam / rubber, then link to its specs for this use case,
etc etc
