Default What is a good simple way to add a house battery to my truck?

Sorry if this is too off topic but I was hoping someone here could help since most fishing boats have separate cranking and house batteries.

I want to add a house battery bank to my truck and have the alternator charge it. the house bank will be in the bed under my top and consist of two group 27 deep cycle batteries. It will be used to run a 2500 watt inverter and a 12 volt fan and lights for camping. I would like to make it easy to put in and remove as well. Maybe build a wooden box to keep it all in and have an Anderson connector to take the whole thing out.

The truck is a 2015 f150 and has a 200 amp alternator. In my old truck I used a noco isolator but the charging system is a lot more complex on the ford and I don't want to mess with it. Is the trailer plug the way to go or would a blue sea acr work?

my guess would be it would wear your alternator out a lot faster trying to charge that many batteries. especially if you run them way down camping. generator would probably be a better route. the honda 2000's are quiet.

You might be able to get by with just using a combiner and not need the alt. Like this one:

I have one in my garage that I do not need. Let me now if it will fit your use.

I already have the batteries and inverter. I also have a generator but it is big and loud and not permitted at a lot of campgrounds.

I don't think you need a generator, tho it's certainly a way more powerful option than any 12 volt battery setup. You might consider running only two batteries total. Replace your trucks starting battery with a deep cycle battery and add another in parallel. Your inverter likely has a low voltage shutoff so killing your battery and not being able to start the truck is less of a concern. Your alternator is fully capable of keeping two batteries charged.

Blue Seas automatic charge relay
The 200amp alternator should be fine

Cool thanks.

I did not think of the yandina. It looks like they make a big one I see on their website that can handle a 500 amp alternator.

I use a SurePower 1315-200 automatic switch like the Yandina. It's great - charges house battery when driving, disconnects them when parked. That keeps you from unknowingly draining your cranking battery.

No problems in 2 years of use and about 50 nights of camping.

I use the Blue Seas ACR in our van, but IIRC both batteries need to be the same for the system to operate correctly. In my boats I use the old school battery switch .

Try a Minn Kota alternator charger. We've had one in a work van for five years with no issues.

It keeps two batteries charged in addition to the vehicle battery. (We remove the batteries from the vehicle and use them to power construction lasers for 8 to 10 hours per day).

The only trick to the installation is to find a switched 12 volt source to control the charger. The easiest way is to located a switched circuit in your fuse panel and install a "fuse tap".
