24 Volt Inverter with a 12 Volt RV System
Hi everyone I recently acquired a 24v inverter along with 2 12v batteries for free. They are from a computer backup system (UPS) consisting of the 24v input inverter along with 2x12v batteries in ...

You can't have the batteries connected in series and parallel simultaneously. Laws of physics/topology and all that.
Some cleverness in switching could allow them to be either 12V or 24V; but in 24V mode you would not be able to power 12V stuff or charge them from a 12V alternator, and in 12V mode you couldn't run the inverter. This would require some rather hefty switches or relays, and you'd still need some additional 12V battery for the other 12V systems in the RV. Mex is absolutely right; there's no real easy and inexpensive solution.
If the batteries are in good condition etc., I would suggest keeping them and exchanging the inverter with a 12V inverter.
