hi,
new here, would also like to thank Stuart (as well as all the others building/testing/modding!) for this brilliant work!
Learnt about diybms less than a week ago (already checked electrodacus and chargery), spent the best part of the last 3 days “studying” - read the whole thread (from post1 all the way to post3953 
) and lots of other threads spawn from here.
Planning to upgrade my motorboat service battery set from 4X6V Trojans cart batteries (225Ah@24V) to 8 EVE280Ah LifePO4 cells in 8S configuration.
Setup is fully Victronised 
so keen on getting both the MPPT and the MultiplusII to be instructed by the Raspberry Pi running VenusOS to stop/start charging/inverting. Real estate limited on a 43ft boat so only have two 300W panels to be replaced with 2 370W ones (same size), a 8kva diesel generator that I try to avoid using if at all possible and main engine alternator. Nevertheless, 95% of charging done by solar.
I’ve setup grafana already and check all boat related data remotely, so cell values will be added (via the victron posting the data received via VE.CAN from the bms)
I have some experience with pcbs (have done a couple of batches with JLCPCB in the past for some boaty NMEA2000 teensy based boards) so plan is to built a batch of 10 modules for the cells as per Jau et al design (DIYBMS for Lithium Iron Phosphate battery cells (LiFePo4) 280aH - #19 by Michaelillingby) and then wait for JLCPCB get their act together to built a ESP32 controller board. Cells ordered this week, so will be here in Greece hopefully sometime in January, gives me plenty of time to sort out a few issues I have -mainly placement and a way to switch from lifepo4 back to the standby trojans if a need arrises - extra relays on controller board will be handy here.
Actually, quite keen on getting my hands on a controller board and test the rpi comms as I have to figure out how the canbus protocol will work with the rpi. So closing this first long post with two questions:
Anyone have a new format built board that is going spare in Europe? happy to buy it and do my rpi comms tests earlier!
Have a couple of ESP32 NodeMCU going spare from other projects, are they compatible with the new controller board?
thanks again for this massive work!
