I haven't come across this company before but they are at the Lincoln show.
UK assembled lithium batteries with BMS and Bluetooth.
Very competitive prices and 24 month warranty.

Has anyone had experience with them?

Eg
166 ah £565
250 ah £760
339 ah £970

No experience, but I'd be cautious as you obviously are. If I understand correctly.... detailed spec suggesting 800 cycles can be extended to 2500 via BMS (Normally expect 2,500 plus for new Grade A cells?) and cells described as showing less than their nominated rating. Makes me wonder what grade of cells are being used and if they are new.

I think I'd want to get detailed informatin about the BMS they're using as well... didn't notice any charge or discharge rates, and didn't notice protections e. g. over/under current or over/under temp charge protection etc.

Sorry if teaching you to suck eggs, as I appreciate you are not asking for that, and obviously proceeding with caution.

They just look too damn cheap to me too.

ps. I'd be interested to see the feedback if you do get any responses to the question you asked too, though!

Good luck, whatever you go for.

Looked to me they are being assembled in a garden shed the whole package did not look very professional at all. I also notice the low number of cycles they quoted made me think not even grade B cells possibly grade C.
Also some of the indevidual cells they are selling are half the price of the main importers again points to sub standard cells.

Just 2 year warranty...Roamer offer 10 years...perhaps another look before committing yourself...

All info is welcome. No rush for Lithium but I wanted to share and get more informed opinions. Chap on the stand seems to know his stuff but then I don't know enough gritty detail either.

I have a 250aH unit on the way to me
Looked over the build, been invited to visit his place and I liked that they are supplied with Anderson plugs instead of the normal bolt options
Cycle rate quoted is minimum expected from a build that is being taken down to 5%
BMS is bluetooth and programable
I will be setting the cut off at a very conservative 20% and Gary told me to expect better than 2000 cycles at that
The two year warranty was set after some muppet wrecked a 4kw setup in 4 years by constantly draining it to zero

I would advise folk to speak to Gary and ask him what ever you like.. he does not seem to duck any thing you ask
They are in Ipswich and welcome visitors
