Long-time lurker, first-time poster. Surprised not to have seen this discussed yet but I guess there's less of us off-grid in the UK and this is only really good for small van/boat setups.
Fogstar DIY 12v kit with Envision Grade B 315Ah - £350
Here's a good unboxing/assembly video (but I'd only torque to 4Nm!):
Frankly this looks like a steal at £350 delivered (8.7p per Wh), call it £50 per cell plus £150 for a solid-looking metal case with compression and BMS. Fogstar confirmed that it comes with the JK B2A8S20P (with CAN/RS485) and the output terminals are M8. Preordered mine to replace 300Ah of tired AGMs in my boat, gonna drill an extra hole in the case to run the UART out from the GPS port to talk to my Victron gear. Not sure if the BMS has the optional heat interface but not bothering with a heat pad as in any case it never gets below 0 in my engine bay, and running the engine to charge in winter will warm them up anyway. Absolute max temp they'd see in the height of summer is maybe 40C.
Got a couple of adjustments to make to my current setup, swapping the ArgoFET for an Orion XS for alternator charging, and moving the SmartShunt from covering everything to just the DC loads so they're compensated for in the charge/discharge current limits. Easy peasy!
