Auxiliary 12 volt battery

[powerman]

Any body know what the lowest voltage the auxiliary Battery can get to before it fails to start the inverter etc to get to the READY  status so one can drive the car? Just curious to know what the critical voltages the system will tolerate.

I think I had it as low as 8

Anything below 7.5-8v will make the electronics freak out, the biggest draw would be the contactor/pumps, as the current rises the voltage will drop it all depends how low the Battery is it may show 12v on a meter but under load it will drop to almost nothing

Surprised it would go down as low as 8volts. Thought the cut off voltage may have been closer to 10. 5 - 11.00 volts.
