I have a desk top i want to instal in my van . We go and study life in the mountains and photograph and record alot of sounds and things of that sort. I want to instal a computer in my car to study what we have recorded or photographed out in the field. We spend days out in the desert . So a computer is a must. I have figured everything out including a built in desk I am instaling. My question is the power supply. I planned on running 4 car batteries connected together in series and add a power inverter. We are a non-funded group / so our equipment is either savaged or donated. We would love to go out and buy the appropiate equipment. But I must frankenstein this one myself. If their is another way to supply power to a car please let me know. any help would be appretiated and will be for a good cause.

Why are you using a 48 volt subsystem? There are 12v dc
power supplies for computers that are more efficient, On another
point there is a lot of impact and vibration. A laptop will probably
sustain less damage than a desktop and take less room.

Connecting the batteries is series makes no sense at all. Connect them in parallel. 12 volt power inverters are much more common and probably a lot cheaper.

But I agree with Fred's advice, it would make much more sense to use a laptop then a desktop system. It's also smaller and can be hidden better from thieves.

It is true a lap top would be eficient. But we are working with what we got. Most of our equipment is either donated or savaged. I have a 800 watt inverter with a peak of 1600( Donated) I planned on running 4 reg car batteries . (You are right not series, but in paralel) instaled in a long plastic tool box. with the inverter mounted on the top of the chest. Right know it is all I have to work with. I figured I could buy a battery charger and charge the batteries indivisually. We need enough power to run a VCR , DVR ,with 4 Infrared night cameras that require a 24 volt power pack per camera, thats 4 of them. a pc tower and a monitor flat screen 22 inch. We record out in the wilderness/desert for about 6 hours constant. So i am trying to figure out how to produce efectively and economically power to these items for about 6 to eigth hours. We normally back the truck up and set the equipment up in the trunk. we set up a chair and let the cameras record nature. This takes place at night. I want to prevent myself from hooking up the chasis battery. I dont want to get stuck out there no help and was wondering what you guys thought of this set up. If you guys could helpme think of a cheaper way . We would be delighted and exited .
We dont have much funding would love to take our new donated equipment and figure out how to use it in the wild.

The 24 volt for cameras seems like you are using cctv
equipment. Open them up and check the wiring. They might be
rewired for 12 v. There are digital recorders that record to
memory cards (6hrs 4 mb sd cards 5 watts). The first thing is
reduce your current consumption, then weight. A thought. The
cameras might be using most of the current for IR illumination (Iff
they have it.) It should take about 120 watts per camera
reduceable to 50 watts with proper equipment selection.

Go to a store that sell parts for campers. you can buy devices with isolation diodes that allow the alternator to charge both the car battery and the auxiliary battery when the engine is running but isolates the auxiliary battery so it the load won't discharge the main car battery.

Actually they are cctv cameras. I found out they are great when recording video at night. It also does record onto a hard drive and they doi have a 12 volt output also. Some do have ir lights on them for night vision. I appretiate all you guys and ladies help. I remember those isolatin diodes. I remember using those in high school. They prevented the power from returning to the oposite way. I would love to get he proper equipment and with time i should have it instaled and functional this spring to record some wild footage.
