My 6-volt Lunatec V2 shut down after only about 3 hours of use last night. I assumed the battery had just died prematurely, so I switched over to a spare I had in my bag. Setting the battery to 6 volts, it would only stay on for a few seconds before the "low battery" light on the preamp would come on, and then it would shut down again. In desperation (I was missing the show!), I set the battery at 8 volts and it worked fine for the rest of the show.
Any ideas on what the problem is? Calibration on the V2? I checked the first battery when I got home, and it was showing half-full still. Am I subject to damage the V2 by feeding it 8 volts?
Thanks for any advice
