I also just ordered (8) of the Lishen 272AH LiFePO4 Prismatic cells from Emily Peng at Basen. I was looking at the Link for the 280AH EVE batteries and while the qty said they had several thousand in stock, both Basen reps I spoke with said they sold out the previous week and apologized that the count was showing wrong, and directed me to the Lishen 272 as they can output over 280AH and had those in stock because they said they were not sure they would get any more EVEs in stock. I saw Max's post about the cargo ship loss, and wonder if they ended up using up lots of the Basen stock of EVEs for replacement of customers who lost theirs at sea. My price was $75/cell plus shipping. So with the Daly 250A BMS I mention below, and shipping and PayPal fees, my total was $999.60.
Anyway I was just looking at that Heltech smart BMS you posted, Peter, and I'm probably reading the specs wrong (I'm a first timer newb), but it looks like the voltages they are posting in spec page are alarmingly high? It says charging voltage is string plus 4.2v so I would interpret they are going to charge your 8s string at 33.4v instead of the 3.65 each max total of 29.2v. Am I missing something?
For my set up I discussed BMS with Daly and would have liked two parallel strings of 4 cells running two BMS at 12v, but they said their BMS doesn't support parallel and that I'd need to go with the 8s 24v Smart BMS instead (putting all 8 cells in series) for my bank. In my case I wanted to have extra capacity so I am going with the big 250A BMS. The model of BMS is the DL-R32W-F08S0250ATJ-MM00
Anyway I'm also only going to be running a small infrequently used solar setup for outbuilding, with this setup, and starting with 4x 12v 200w panels. I don't think I'll care how long it takes to charge this bank, as I won't expect to drain it much, and in TX we get lots of sun.
Hopefully I am not missing something incredibly stupid!
