We have 440 AH total with our 4 AGM batteries. We have a 1200W pure sine inverter. We have a 900W coffee maker.
At about 6AM (no sun), we typically have 80% battery left showing about 12.6V.
When the coffee maker turns on, we show 93+ amp draw. Our voltage drops to 12.0 under the load.
If we tried to make coffee with less than 65% of the battery, the voltage dips to 11.8. The inverter gets hot and the fans kick on. So we don't. After brewing the batteries recover quickly - back to 12.5 or so, and we have used about 12 AH.
I only post this to show you our real world experience. Personally, if we had two batteries, I wouldn't do it. Especially with a larger draw.
