48 VDC Kwh Battery Pack
Amazon's catalog no longer lists this product (checked 2026-11-02). The name comes from the link HN users posted.
A 100kWh battery would run a 1kW bar heater (and nothing else) for 4 days. That's probably enough to heat one room and keep you alive, but it won't be giving you the full electric shower, cooking food, warm house and pipes not freezing experience. Even moreso if you want to keep some reserves in case it needs to last more days.

A long one. 100kWh will cost you maybe $70,000 (e.g. 10x of these https://www.amazon.com/48-VDC-Kwh-Battery-Pack/dp/B079348MM1 ) (If it's not LiIon, but is lead-acid to be cheaper, you won't want to be using much more than 50% of it before it causes problems). At $1/kWh from the mains, about 8 years of mains electricity to buy it. At $0.25/kWh, 32 years.
