Recommendations for sourcing 3.2v LifePO4 "EVE" or other quality cells in the UK?

Looking to source some quality 3.2v cells for a DIY battery, but am based out of the UK do don't have access to local stores in the US, only direct ship from China.

Doncan Technology looks to have good cells based on the forum thread however I cant access the US stores so have to rely on China shipping and the appropriate taxes.

I wondered if anyone from the UK have any tried and tested suppliers for 3.2v cells for shipping that I could purchase from with peace of mind, or if Doncan for example cells would be identical even if I order direct from China?

My goal is to make a 24V 200Ah or similar!

For Europe I usually suggest Dongguan. They ship it by train.

We have more representative from the company here like @Hayley Miu . So you can write directly to her here or on the Alibaba chat.

Also you can find some Dongguan order and then cells test post here.

Thank you

They seem to have 2 different options. Do you know which would be the better between CATL and LISHEN?

I like the EVE cells more. Least problem with that.
Also if you can go for the 280Ah version. The price / Wh is better.
But to choose from CATL of Lishen ... which one is better? I do not know.
CATL cells use the Tesla Model 3 cars. But here is some CATL 310Ah cells that get a bit puffy.

Super thanks for your advice I am contacting them, however cannot see EVE cells on there alibaba listing at least

Any recommendations for a 200A BMS and balancer? I was going to go for the non smart Daly (I think its 250A), but open to advise!

Ask them. Sometimes they write only 272-280Ah and that is Lishen or EVE.

For 48V I would say to check out here the JK Heltec active balance BMS


But for 24V ...
I do not like Daly.

I have been using the non-smart Daly (80A/16s) as a newbie. I found that curiosity and other concerns (dodgy cells from OYE store) lead to me manually checking voltages often as they approached high or low charge. With hindsight I'd just paid a little more for the smart one, and I'll certainly go for it if I do another DIY pack build.

I understand you can also adjust the cutoff voltages with the smart one too. On the 80A non-smart the low voltage cutoff is 2.2v (even for LiFePo4). Practically, cutoff will likely occur under load, i.e. with some voltage drop, and on disconnect the voltage is indeed around 2.5v BUT I still find it a bit low/disconcerting.

Oh, I'm in the UK too (not that it's relevant).. nice to see others having a go.
