Hey good Neighbor, fun post....... You state as follows....
'So voltage doesn't always tell you to condition of a battery, especially if you just charged it.' YES YOU'RE EXACTLY RIGHT
GOOD QUESTION George, the answer is NOOOOOOOOO (but you already knew that Im sure) FYI A battery experiences voltage RISE under charge but voltage SAG under a load....... Voltage alone can provide a somewhat fairly accurate, albeit not perfect, indication of its State of Charge (SOC) BUT ONLY ONCE ITS AT REST AND STABILIZED.
