SMA Home Storage 16.4 is made up of five lithium iron phosphate (LiFePO4) modules, spread across two towers of different heights, for 16.40 kWh of usable capacity. It pairs with the three-phase Sunny Tripower Smart Energy inverter, which supports 2 to 5 modules; the single-phase Sunny Boy Smart Energy goes up to 4 modules at most.
The battery doesn't work on its own: it receives updated software from the connected inverter. The warranty is also tied to the energy transferred, with at least 60% of usable capacity at end of life.

The rest of the data comes from one page on the manufacturer's site, cited row by row in the table above.
A manual or a datasheet counts as a source even when the original file is hosted elsewhere: what matters is the document, not the server. Where that happens, it is stated above.
These numbers are calculated, not stated: they have no source to cite, they have a formula you can redo. The price used is the manufacturer's list price, which is stable and the same in every country — not a shop's price on the day.
