47-55.1 Battery Placement Question

[joedoh]

why not under the hood? lots of room and closer to the starter. someday you may want to haul something in the bed, or more importantly you may want to haul NOTHING in the bed.

No room under hood now with vintage air installed. I was thinking the storage box and use the battery holder mounted inside of this. Then I can use it for storage as well.

don't forget to vent the box.
the last thing I would want in my truck box is a battery box or anything permanently mounted like that. ia battery is really is a rarely serviced item these days, why not on the frame or something? still accessible if the battery box is built for that plus totally out of the way.battery closer to largest current draw item is best or at least install the correct gauge cable for the starter draw.
your truck, do it how you like it. you can always change it later if you don't like it.

Thanks. Yes planned on doing some venting as well if I end up doing this. I just was thinking I could close the floor access off and do that.

it depends on the max draw, from starter usually. the temp. the length of the cables.
take a look at this, it's for winch cable but a winch motor is like a starter motor

or this from crutchfield, scroll down for the chart

you also need to either have the cable ends installed for you or ensure you get it right so you don't end up with a high resistance cable terminal that will cause a voltage drop and a heat source. if you try a starter/alternator rebuilder they will usually be able to supply the cable required and also install the terminal ends required for your application. cheaper than buying the crimp tool likely. they may also have red cable to mark the positive for you and will install proper shrink tube over the crimped terminal ends. ensure to install a ground strap from the engine to the frame and cab as well. frame to rad support is also a good one that is commonly overlooked. anywhere that supplies a ground to an accesory will need to have a dedicated ground. there is no use running the headlight ground to the rad support if the rad support isn't grounded.

unless under your hood is more crowded than mine, I am going to politely disagree

I cut a tray in the ONLY SPOT it would fit on this truck. on another truck I hung it from the passenger firewall and on still another I hung it dead center firewall above the engine.

¯\_(ツ)_/¯


it did though! the battery couldnt go forward any, back any or even down any. you cant see the PCM under the air box either.

You did a good job. Is that a 4.3 or 5.0?
