I may have access to a large number of Incell/Polarium 48v 50Ah (SLB48-050) at work which have faults (failed cells) that the business isn’t interested in having repaired, so may be obtainable for personal repair.
They have CAN bus connectors, has anyone got any experience using these with Multiplus II?
If you can get hold of the batteries’ can protocol and connection details, you may be in with a chance. Either way, you will need a GX device to translate the can data for a victron inverter - the inverter’s use the VE-Bus protocol, not the can - battery protocol.
