@Will - this battery type appears to be missing from your (most useful) spreadsheet in the locked thread?
Morning Jim,
Thanks, I can see where I went wrong in the sheet, now corrected to simply ECS V1 or V2.
To answer you, these are the battery firmwares:
Battery ECS V2 BCU (Master) 2.009
Battery ECS V2 BMU (Slave) 1.15
Latest inverter:
Inverter H1 Gen2 Master 1.45
Inverter H1 Gen2 Slave 1.04
Inverter H1 Gen2 Manager 1.62
