LiTime 12V 320Ah W190 Bluetooth is a narrow, tall lithium iron phosphate battery, built to stand on edge under a van seat: the width matches an under-seat compartment, and inside it holds a reserve covering two to three days of autonomy, depending on use. The state of charge is read from the phone over Bluetooth.
Below zero the electronics stop charging and resume it on their own once the battery is back above five degrees: it doesn't get damaged, but in a freezing compartment in winter it doesn't fill up until it warms. The continuous current it allows through covers a large inverter with several loads together. It withstands dust and splashes.
It's for anyone fitting out a van who has decided to put the battery under the seat, with plenty of storage and readings from the phone. Anyone charging outdoors in winter needs a version with heating, not just protection.

The rest of the data comes from 2 pages 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.
