Source of small LiFePO4 cells?

Does anyone know a UK supplier of small ‘raw’ LiFePO4 cells?

I am thinking about making a 48v LiFePO4 pack to power a few low voltage electronic devices that are always-on in my house. I am on Octopus Agile, so it would be good to be able to power them reliably for long periods of higher energy prices.

But the smallest prismatic cells I can find seem to be 3.2v / 280 Ah, which is massive and too expensive for my needs. And the best cylindrical cells I could find are too expensive:

(that works out at about £800 per kWh!)

Hey Nicolas, I order mine from china slim pickings in the UK, and the USA

Gotion has a set of cylindrical cells that are reasonable and available

I’ll post some pricing and a contact person you can buy from shortly and see if that gets you what you’re after

See if any of those are good, these are prices in china so still need to add shipping and tariffs if applicable
