I have been sitting patiently on 10 (ten) Model S battery modules since march of this year (2020) researching every single BMS solution I could find - and yours FINALLY looks like the one I'm really interested in specifically because of your Victron integration :D We're building out our system with a 48v Quattro 5000. I'm going to head over to your website and give you a direct message in the morning - I'll be the person with the Tour Bus in NC over in the states.
Are you comfortable to parallel up tesla modules with this BMS? so put the actual modules in say a 2S5P configuration to get a 44.4v (nominal) but big Ah capacity? I ready that you shouldn't really do this
Yes you can. But use quality fuse near the battery. One parallel string can deliver 3000 Amp short circuit current. 5 parallel strings will deliver up to 15000 Amp short circuit current. The interrupt rating of the fuse must cope with this. I advice Class T fuse(littlefuse). And make sure the voltage is identical when connecting the parallel strings.
