FS7: FS7 Ballery solutions....Can 16 volt batteries be used wothout burning circuituit bds

[Scott Ransom]

I have always used 14 Volt AB batteries with my FS7.(altho they actually rate at 16.4 on a voltmeter. My BP U60's rate at 16 volts even though they claim 14.6. What range of voltages will the FS7 accept? Bottom line can I use 16.4 Volt batteries on the FS7?
