That could be correct. The starter is a huge drain and the voltage will drop a lot if it's turning or trying to turn. The batter should be more like 13V when fully charged and probably show over 14V across the terminals when the engine is running - that's from the charging circuit.

I don't know the exact figures the above is approximate.
