Should I switch batts?

Are you referring to me I hold 14volts at full tilt at idle with 9000rms I have a dcpower sp270 7 deka 9A31's and a 9A78 up front the stingers are good but the dekas are stronge in my testing anyway. But my amps are more efficient than yours is.

No not exactly but you do fall in that category. I see you have alot of batteries. I don't really have much room for more batteries. I guess it will be ok.

You should try replacing the stingers with deka 9A31's I bet your voltage situation replaces.
