moving the battery
looking to move the battery behind the seat in my 78 f150. Actually planning to have one in either conner in marine boxes.
I was just wondering if anyone had done this and had any tips for me.

If you can...use some electrical groumets for the areas where you need to pass into the cab...this will prevent the wires from rubbing on the sharp metal edges of the hole and wearing through possibly causing a grounding issue.
It should be a fairly straight forward operation...are you working with a re location kit or are you making the wires yourself? If youre doing it yourself you may be able to find everything you need at a local ACE Hardware if you have one...I was in there the other day and happened to notice that they had both the terminals and the groumets to do it....all you'd need is the proper gauge wire.....I noticed because Im actually planning on doing this on another project of mine very soon.

Moving the Battery
I agree with the earleir posts that moving the battery from under the hood to inside the passenger compartment could be a very bad idea. If you feel you have to do it, you need to be certain of tieing the battery down adequately to keep it where it is in an accident. Maybe even a covered box (like early Corvettes) to keep battery acid from splashing out in an accident/roll over. The potential for shorting is also a big concern. If you do it, don't cut corners or do it "cheap".

Can I ask why you're doing this? Is it for weight distribution or to better protect your batteries? If you have state inspections where you live I'm sure you would need to have the batteries in a well sealed compartment since they're in the passenger cabin, and well anchored. Just curious.

I understand about the gases and risk of acid damage. That is why I am using marine style enclosed boxes. I've seen them used in drag cars for weight distribution. I know will have to vent them out side the cab.
I wanted to see if anyone else hear had done this and where they ran their wiring and vent tubing

Venting
Make sure you at least get the type of battery that has the cells vented to a hose fitting. Cars that have the battery under the rear seat from the factory use batteries that have a hose connection to vent the battery gases outside. Getting the battery acid fumes vented away from the battery has the added benefit of preventing corrosion of the terminals, holddowns etc. I have an Audi 1990 Quattro with the battery under the rear seat. It's got 230K miles on it and no corrosion at all on any of the terminal, cables, etc.

I would'nt recommend doing it either. Not only are the gasses emmitted from a charging battery poisonous, they're very explosive. I've seen one explode due to a small spark, acid was everywhere. If you must move them, how about fabricating a mount between the frame rails and bedside, where the factory tool boxes were?

My ?? is why would you want the batteries inside/behind you ? Battery mounting places are on both front inner fenders. I've got 2 batteries under the hood with an isolator between them. I've jump started a few people, and even myself a couple times with this setup. A lot of off-roaders use the aux. battery for winches, lights, etc.

Guys who drag race the hatchbacks often put the battery in the rear of the passenger compartment.
However they use a steel box for safey reasons. These boxes have seals for where the cables pass through, and a vent tube that leads to the outside of the vehicle.

this is the type of box I am planning to use.
As to why I want to do this,
1. I have a goal of dropping 200lbs from the engine bay. while relocating the battery won't be that much of a weight difference, combined with other small changes it does add up.
2. Want to have 'bare' engine bay, mainly for show.
3. because I can and its something not normally done in trucks.

that does not appear to be a sealed unit that MUST use
go to jegs.com and search for battery box
as said before a custom mount on the frame rails
would be cool and more practical
some type of unit that would allow easy drop down would
be interesting to many here if you could design it
OH, and of course post for all of use to use
