2 x 100Ah LiFePO4 - using 2400w = a possible 55 minutes?

[Peter Clark]

2 x 100Ah LiFePO4 - using 2400w = a possible 55 minutes?

Using an online calculator I arrived at this figure.

Would anyone with real world expertise say this number is in the right ballpark?

PS: Victron batteries via Victron 3000w inverter 12v system.
Maximum running at 2400w would be 30 minutes.

26 amps @ 12 volt d.c. to produce 1 amp @ 240 volts a.c.
2600 amps per 60 mins allowing for inverter inefficiencies
what is the max discharge from each bat.
