Hello,
?
I have a QMX that is built for 9V. Now I'm making a custom LiFePO4 battery for it. My question is, what's the maximum input voltage that the QMX can handle before it breaks? Given that each LiFePO4 has around 3.55V, if I connect three of them in series, I'll get around 10.65V, is that going to damage the radio??
?
Thanks,
