Amazingly Simple upgrades For your 12v System

Updated: Jun 1



Hey Im back as promised with my simple upgrades for your minimalist 12v system.


If you are reading this post there is a good chance you have clicked on it from one of my 12v minimalist set up posts and your looking for something a little extra, if you haven't read them yet you can check them out by following these links.

CLICK HERE FOR B2B CHARGE VERSION



In the Minimalist posts I include a Six way blade fuse box but by the end of the install you will have three spare spaces so if you wanted to you could add three more accessories. I will also include links if you want to go for a bigger system with more power and more accessories.


You can use it as a quick guide to what you will need, for estimating your costs, for ordering stuff hassle free and as usual for my personal recommendations on brands and specific items.


I hope you all enjoy




ADD MORE POWER STORAGE


As I said in my12v minimalist set up posts both both solar and charging from your starter battery both have limitations. Solar is only really efficient in the summer months when we have longer days and shorter nights and Split charging and B2B chargers are only good if you are not parked up in the same place for longer than a couple of days so a good thing to do is add more power storage.


The way to do this is to add another battery (or more) and wire it (or them) in parallel to your original leisure battery. There are two things you should know before you do this...


The first is that you should always use the same AH battery so if your original leisure battery was 110AH then you should get another 110AH battery. You should also buy all of the batteries that you are going to wire in parallel at the same time so they are in the same condition from the start.


The Next thing is they should both be at the exact level of charge when you connect them together. As mentioned above ideally you will buy them all together. If you are adding an old one to a new one make sure the old one is holding its full charge, it's the same make and AH and both have a full charge.


So with that in mind and because I recommended this exact same battery in my other posts thats what i am recommending in this post. Don't forget if you are reading this before you have started you electrics order all of your batteries at the same time. As an amazon associate I earn from qualifying purchases

You also need 2 x Cables for each battery you want to add. To wire batteries in parallel you simply join positive to positive & negative to negative.


You should try and keep your cables as short as possible so there is enough cable here to join a few batteries together

You will also need another set of battery terminals per battery you want to add. Unlike in my other posts where I recommended a different set of battery terminals (https://amzn.to/35coehQ) that are good for attaching fuse box's, solar charge controllers, inverters etc these are good for joining batteries together and are cheaper.

UPGRADE OR ADD MORE SOCKETS


You might want to add some more sockets to your up if you have a few bits and pieces that need charging at the same time. You can go nice and simple with something like this that includes everything you need to attach it to the fuse box (if its really close to it)

If you have any modern devices like phones, cameras, drones etc that are compatible with with quick charge these are really good and will charge your device a lot quicker than a standard 2.1A socket. This particular socket comes with a built in voltmeter so you can keep an eye on your batteries condition.

Better still a lot of new devices now like some laptops allow you to charge them via USB C and to be fair USB C is a lot better but for some people this little socket will eradicate the need for a power hungry Inverter. It is also Quick charge like the socket above and it has a normal QC 3.0 usb socket. What more you could you want?

***NEW ADDITIONS 2021***




A 30 amp lighter socket is your only real option if you want to use something that heats up for example a 12v hair dryer or if you have one of those 300w inverters with a lighter socket on the end of it.


300w ÷ 12v = 25 amps


Although 12v hair dryers and the small inverters are 12v and come with a 12v cigarette lighter plug on them if you tried to plug them into a 10 amp or15 amp socket or even your vans lighter socket it will blow the fuse straight away as most 12v hair dryers require about 18 or 19 amps constantly.

ADD VENTILATION


One thing that I did not add to my budget system lists but most people can't live without is ventilation. It can get quiet stuffy and smelly in the back of a van and also unventilated vans suffer from a lot of condensation.


There are obvious favourites to go for like the MAXXAIR DELUX that are just amazing but there are cheaper, stealthier ways to ventilate your van if thats what you are looking for.


So if you are looking for the Rolls Royce of roof vents this is what you are looking for...

If you can't afford the Maxxair fan there are a few cheaper options that work just as well as the Maxxair but unlike the Maxxair they can't be used when it is raining outside.

If your looking for something a bit cheaper or stealthier you could look at getting something like this. They are low profile and are fitted to the side of your van so you don't have to cut holes in your roof.

UPGRADE OR ADD MORE LIGHTING


If you have very basic lighting in your van you might want to either upgrade your lights or add some more.


There are a few good choices out there but most people either go for Downlights or LED strip lights.



For downlights the easiest type to install in a van are touch sensitive LED downlights. You just touch each light to turn them on and off so there is no need for light switches and all the extra hassle, cable, connectors, and various other bits that involves. These are cool white but you can also get warm white.

If you are going to go with these lights for simplicity you might want to just add another six way fuse box and wire all your lights to that. Then they are all in the same place and it saves much needed space on your original fuse box. All cables, connectors and fuse box can be found in this post.

If you would prefer to be able to turn the lights on and off with switches then this is the best type to go for. They are slightly cheaper so thats a good thing and you can wire each light up to separate switches or group them all together so they can all be turned on with the same switch. Again these ones are cool white but warm white are also available.

If brushed chrome isn't your type of thing there are other options but these are quite cheap and will suit a lot of builds too.

LED strip lights are also awesome for vans and they come various forms too. The cheapest is the NON waterproof ones that you can find in my original post below

Then you can get water proof ones that are so much better but a little bit more expensive. they are great though I have put them on the outside of vans, in showers, in footwells etc. They are really robust and can take take quite a bit of a beating as they are covered in some kind or rubber. The non waterproof ones the bulbs are pretty much unprotected so damage easily.
