seems canbus is quite 'workable' as well, and as far as I can judge the trick is to get your canbus board connected and once that's fixed there's only a few standards to go with (I read there that pretty much any canbus compliant BMS should work????)

As it's opensource and 'free', the amount of documentation is depending on the time people have available. I'm using it with a RS485 connection and a usb adapter in the Raspberry Pi I'm running venusOS large on

https://github.com/Louisvdw/dbus-serialbattery works like a charm!

https://www.nkon.nl/rechargeable/lifepo4/prismatisch/eve-lf280-prismatic-280ah-280a-lifepo4.html They've got the cells u are looking for!

nope i ended up with 8 of these: https://www.alibaba.com/product-detail/Eu-Us-Stock-Grade-A-280Ah_1600219202538.html?spm=a2756.order-detail-ta-ta-b.0.0.43a32fc28cw7Cy good stuff. added a JDB bms.

the software did seem to do a better job in setting this specific parameter

I've got this 6-21 cell BMS AP21S001 200A, all works fine. Only parameter I can't seem to save is the total capacity. It gets saved and returned when i read the config, but the app (and also the driver I use to read stuff to vitron VenusOS) is stuck in thinking I've got 280ah in my 200Ah...

more or less my approach. Clamped all 8 together with 4x m10 rods and plywood at the ends. Used a 17mm socket (without the handle) and hand tied it while the pack was more or less at ~90% SoC. Put them in top balancing (flipping half of the cells) and hand tied them again for top balance...

https://www.alibaba.com/product-detail/Eu-Us-Stock-Grade-A-280Ah_1600219202538.html I've had 8 of these. production dates all december '21 They come nice and reasonably balanced. Now charging as a pack and I'm delighted to see there isn't one cell ahead or behind (highest and lowest cell keep...

My apologies for the accidental hijack of this thread. Back on topic. Anyone information on getting LF280 cells in Europe?

ordered the ones above on sunday evening. https://www.alibaba.com/product-detail/Eu-Us-Stock-Grade-A-280Ah_1600219202538.html Got shipped from Poland,EU (stock) to Amsterdam, Netherlands. first 4 arrived on thursday, the rest on friday.

Got delivered in less than 5 days! Cells look brand new! first impression of QR is that they are from same series (will have to look them up later on) Voltage match = perfect, all 3.304V Rest will have to wait to installation day.

yes my bad. https://www.alibaba.com/product-detail/Eu-Us-Stock-Grade-A-280Ah_1600219202538.html ordered those. Seems to be a compagny with a long long history. Also they are realistic in measurements. Dec 2021 stock, assuming slight degradation 272AH should be possible with a well balanced...

https://www.alibaba.com/product-detail/Eu-Us-Stock-Grade-A-280Ah_1600219202538.html This party seem to have a LONG history. I'll look in the vendors you mention. I've got 2 separate parties saying theres December 2011 stock in Poland ad the moment. Thanks!
