Packs, battery packs. This is very common for DIY ebikes.

  It used to be that one assembled batteries of cells. But language changes I suppose.

    In this case, each cell is also a standalone battery (an 1850 I presume). Assemblage of these is either called a module or a pack.

      An 18650 is a single cell. (Or a battery in modern parlance.) Now, get off my lawn! :-D Just kidding! The terminology shifted. But a cell used to be the single unit of chemistry and catode and anode that gives the native voltage. So an 18650 would be a cell. A 1.5V alkaline would be a cell. A 9V alkaline would be a battery of six cells! And so on. I'm not saying it's wrong nowadays to say an 18650 is a battery.

  Not even disagreeing with you, but it's a funny evolution of language when you consider the origin of the term battery. https://en.wikipedia.org/wiki/Artillery_battery https://en.wikipedia.org/wiki/Artillery_battery We owe the term to Benjamin Franklin, who used it to describe what you're referring to as a pack (although Leyden jars are considered capacitors rather than batteries in modern terms). https://en.wikipedia.org/wiki/Electric_battery#Invention https://en.wikipedia.org/wiki/Electric_battery#Invention
