I am tasked with evaluating if it is possible to design a 24V system that has 40-50kWh of storage. That would be 8-10 200A Smart batteries. As far as I know the maximum allowed parallel batteries is 5 with the Lynx BMS. The question is, if it is supported to have 2 battery banks of 5 parallel each. i.e 2 Lynx BMS.
Consider 48V to 24V DC: DC converters
Consider a core 48V battery with a 24V system for the consumers, that's fed from the 48V system.
Might be better to discuss with a dealer. They will need much more information, of course.
Here was also a boat Configuration with 24V at Lagoon 620 Karamaran, now changed by victron dealer to 48V and 24V powered by Orion and small 24v battery for anker, winch etc :
Thanks for the answers. The question was not wether it makes sense to go to 48V or a different system. I asked specifically if it was possible to combine 2 battery banks with 2 separate BMS into a single system.
I have had some time to dig into the Venus source code, specifically the dbus_systemcalc.
It does not look like this is supported, as a single monitor or BMS is picked. I also did not see any code to sum up 2 BMS.
It looks like as it would be possible to create a virtual BMS that takes 2 or more existing on the dbus and presents it as one. And then pick that one.
I suspect that alone would not be enough, as there would probably have to be some synchronization / equalization before paralleling the 2 or more banks.
Is there a documentation out there for the Lynx BMS VE.Can parameters ?
