Running lights etc off a battery

Postby Bomber_WA » Wed Mar 18, 2009 5:45 pm

Hi All,

I am just getting into the camping game and just bought a camper trailer.

We are just going to be going away for 2-3 days max at this stage so I have decided agaist buying a fridge/freezer.

I do however want to run a few lights/phone chargers/laptop etc. Can anyone suggest the best way to do this? Without having a duel battery system in a vehicle....

Can I just get a deep cycle battery and run these things with a sine wave inverter. How would I charge the battery again either at home or out and about???

Cheers

besides installing a battery in the camper trailer, you could consider these packs http://sidewinder.com.au/page18a.html inverters have there use, however if you want to run a laptop off one, youre best to get a 12v laptop power supply. You can get them from jaycar. Lighting wise you may already have this sorted, but LED or 12v Fluro is the go.

For just a couple of lights you might get away with a battery kickstarter. They are charged by plugging into power point at home and running a light will last some days. The more appliances you want to run the more power and storage you need. Then its a slippery slope to dual battery systems, solar panels and generators. :grin:

Get a couple of 12v LED fluros for lighting, as for the charging and running of the others, your gunna need some way of keepin charge up to the battery in the camper, a small solar panel (20watts) will trickle charge it during the day, idealy you should have a contoller to charge the battery from the car as well, this way it can be charged while driving to the camp spot your going too, the controller can be in the camper if you don't want a dual battery system in the car.

I have a controller in my camper that charges the camper battery while driving, it is isolated when the ignition is off, if you need too you can just hook the car up and charge the camper battery via the car by leaving it running for 30mins

Charging the camper battery at home is just a matter of plugging the battery on to a 240v 3 stage charger, these charger bring the battery to full charge then trickle charge it to maintain it at full charge untill your next trip.

Go deep cycle (agm) at least a 125ah so you can use 90ah.... never use all of it. and hook up a solar panel. Springers.com.au they have it all.

I went to BCF store which are here in Brisbane and for $13 I brought a three way connector system like ya have on a boat that they attach to the dash of a boat. I mounted that on a peice of wood and made up three separate metal connectors that I attached to the wood and numbered them one to three.So you have three individual switches (ON/OFF), with fuses with three separate power leads. The three switches are all on the one peice of alumiunim so all i did was extended the one negative lead as they are all connected as one and applied a O ring connector so I can attach it to the battery. The other three individual red power wires I also extended and applied to three separate metal connectors. Then run a positive cable from the 3 way switch to the battery and I applied another O ring. I have one peice of metal attached to the wood that is big enough to accept 3 negative alligator clips.
I have a normal car battery in a battery box, I apply the positive n negative terminals from my 3 way switch thus i have three separate powerpoints you might say. So I run a 11W light off one, a car radio and my 12V truck van off all of this. So I connect them all up. Thats is all negative alligator clips to the one metal earth on the wood and the other three red leads to each of the three separate respective metal plates. So at nite i might just have the light on so I turn it on or i might need the fan on to so I have two switches on. All two easy and ya just leave it that way the whole time ya camping.
Its all compact, sits on top of my battery box and each item has a alligator positive and negative switch on it.

Yeah I am going camping next Wedenesday so will take a picture for you. Will also take a picture of a 11W light I made out of a lead light. All I did to that was cut the power switch off and added a cigarette plug in to that end and brought a 11W 12V light bulb from a light shop. So u end up with a covered light bulb you can hook up with a 5M lead. Awesome.
