Wired correctly

I would like to make sure I have my system wired correctly for what I'm trying to achieve.
Have a 1200 watt inverter with 2 x 12v (105amp) batteries.
If I've wired it correctly it should still be giving me 12v but with 210amps
Inverter positive is going to battery #1
Inverter negative is going to battery #2
Positive from battery #1 and #2 are wired together
Negative from battery #1 and #2 are wired together
Hope this makes sence......

Yep, you have it correct... Just to clarify:
The reason for the batt#1 and batt#2 terminal positions is so that each battery sees the "same resistance"... If the load terminals were attached to battery #1 only, and jumpers to battery #2--number one will see the "lowest resistance" and supply more current than battery #2 (because of the extra jumper cables/connections). And, typically, battery #1 will wear out faster...
Alost, when you say give you "210 amps"--this is really 210 Amp Hours from 100% state of charge to 0% state of charge at a 20 hour rate (or 210AH/20H=10.5 amps for 20 hours--of course, you normally should only use 50% of this--so 10.5 amps for 10 hours).
And, your battery's apparent capacity is higher at 20 hour and 100 hour rates, and lower at 1 hour and 10 hour rates (the higher the current, the more the internal resistance of the battery and chemical processes waste more energy by turning it into heat--similar issues when charging).

Thanks for the fast reply..... yeah, I meant to say 210 amp hours with both batteries together
SA,
Just give me a quick swat if my replies continue to increase in length
Obviously, I am also trying to help other who are new at this to understand why the question was asked.

Connecting on the "diagonal" will extend the life of the batteries by helping share the loads.
