I thought I'd offer them here first.

I have 2 x US2000C's which were Spanish imports badged as Turbo Energy by Pylontech. I've used battery view and debug software to give some info on their current state. I've use them for under 3 years old, both have SOH of 96% and have clocked 434 and 443 full cycles respectively. I am after £350 per unit.
I also have 7 x US2000B (Plus version) which I've used for 7 years but have only clocked between 655 and 684 full cycles each. I am after £250 per unit.
No issues with any of them, all cells with minimal voltage variance, I have battery view screenshots for all of them.
The disparity in cycle use verses age is because of me cycling them much more over the past year on Octopus Outgoing.
I also have 9 x stacking brackets for all the units, quite happy to throw them in with a unit or £10 per pair without.
I have the Servtec cable and software, looking for £20 for that.
Free collection from Southampton area or £20 postage per unit. If anyone wants multiple units I could also deliver up to 100 miles away and I'm visiting my mum in Preston soon so I could drop off anywhere within 100 miles on that journey so that would include quite a lot of the country.
Or £2k for the lot, should still be 20kWh+ of storage there.
EDIT - To change the number of available pairs of stacking brackets from 7 to 9.
