If I connect them to the pos. and neg. terminals of just one of the batteries will they get just 12V, or will they get over-juiced at 24V?
That will be fine with respect to the voltage delivered to the strip, however if these batteries are charged in series, you need to keep the load on each battery as close as possible to the same.
If the LED strips are identical and use resistors to limit current, you can connect pairs of these in series and power them from 24V.
Note that connecting strips in series IS NOT the same as connecting one strip to the end of the other.
If you connect the - of light 1 to the + of light 2, then you can connect the + of light 1 and the - of light 2 up to 24 volts.
Do it like this:

If you want to connect another pair of lights wire them the same way and attatch them to the batteries too.

I'm not sure a caveman could do it, but I have faith in your abilities.
The controller is rated for 24 volts, so the input connections can be connected to your 24V supply.
The two 12V strips (which are now connected to allow their operation from 24V) can be connected to the output.
Essentially, that controller box slips in between the battery and your LED strips.
Draw us a diagram just so we know you've got it right.
Edit: I've described the connection to the controller on the left, but it looks like the controller on the right is functionally equivalent. The main difference is you have to connect wires rather than connect to a terminal block.
Stay tuned...will get back to this soon. The wife’s “honey-do” takes precedence!
That looks pretty good. I think the joined red and black wires on the battery side are just from the church and paste you did, and that you wouldn't wire then up (they don't go anywhere anyway.
I'm sure you can connect all 4 strips to the one controller if you want them to all be controlled together.
The remote control may operate from a much lower voltage, so beware.
There remote control is probably powered by a single 3V coin cell. Powering it from 12 or 24 volts would probably result in some amount of smoke.
Some larger remotes are powered by a single small 12v battery, but spikes that exist in a car electrical system could damage them if they were directly connected.
There are various ways of providing a safe source of lower voltage, but the coin cells typically last a long time anyway.
Thanks for your help.
