KW and J_R are correct. I suspect you are comparing the transmitter readout (which is always transmitting, thus under load) with a voltmeter reading (battery removed, no load.)
If 9.3 is your fully charged number, however, I think it is a bit low. My Prism, fully charged, shows me about 10.1 or so. What charger do you use?
Good luck

I have a Hitec "Flash 5" transmitter which gives me bogus information about the battery voltage. It shows approx. 1 volt low, as I've tested the same battery with 2 different voltmeters, and for example, they show 10.3V where the tx voltmeter shows 9.3V. I was told that there's a way to adjust that in-unit voltmeter if I take the back off. Well, I took the back off, and I'll be dogged if I can find a hint of adjustment screws for anything electronic. Any suggestions as to what I can do?
