If your batteries are good, you should be able to go as low as 11.8 - 12.0 and still start the generator. It is recommended to not allow deep cycle batteries to get below 50% charge before recharge. (You can go down to 25% - but each time decreases lifespan) Even though 11.8 is below 50% level, you need to take into account that the voltage referenced is taken at open circuit. Since your batteries are generally loaded then you have to adjust voltage downward to compensate.
