The BYD Battery-Box Premium LVS 20.0 is a low-voltage storage tower with lithium iron phosphate (LiFePO4) cells, made up of five modules and offering 20 kWh of usable capacity. It is installed on a floor stand and works with inverters from several brands. It can only be used as a single tower. Usable capacity is measured at full discharge under the manufacturer's test conditions: the real value can vary with the inverter brand.

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.
