RCT Power Battery 11.5 is a high-voltage LiFePO4 tower battery with 11.52 kWh nominal and 10.37 kWh usable capacity (90% depth of discharge). In the double-tower configuration it reaches 23 kWh nominal. It pairs with an inverter from the RCT Power Storage DC family.
The warranty runs ten years from first installation; the accumulator is considered defective if its capacity falls below 80% of nominal.

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.
