Hi everyone,

After some advice/help on getting a second battery system in my vw caddy.

i do not understand watts and amps etc, but want to be able to power my fridge, and power lights, fans, laptop etc when camping.

i have been told i cannot get a second battery installed under the bonnet as it wont fit, and have been recommended that i get a battery pack.

i would like to have several cigarette lighter outlets, as well as standard power sockets for laptop etc.

i have come across this system on ebay, and would like to understand how it works, how easy to install, and basically any comments, so i can try to wrap my head around how these work.


And does anyone know of a workshop that will install something like this on the South side of Sydney.

thanks in advance.

Hi Louise,

You may find our blog on Electricity for Camping useful to help you get your head around what you need and how it all works. Its very easy to spend a lot of money on electrical stuff, so its worthwhile getting it right so that it works as you want it to.

You can contact this business and I assure you get the best advice.
Nothing to do with the firm just a happy customer.

Hi Louise

You need to look at this article first. Battery-Power

Once you have read the article then give us some details on your accessories and how long you camp and drive each day etc.

Have you thought of a Portable Battery System. We have a 105 Thumper and are very happy with it. Go to www.australiandirect.com.au Good Luck

Hi louise,

I just had a second battery fitted to my hilux, same thing it would have been a mission to fit it under the bonnet, so I bought a 100ah AGM battery (they are sealed and don't release gas, so they are safer in the car), a relay that automatically charges the battery when the driving battery is full, and a KEMO battery guard of ebay,


They are adjustable to the voltage you want the battery to go down to and then they shut off to protect the battery from discharging, also I bought a Landcruiser power panel that has voltmeter and AMP meter inbuilt and 4 cigarette lighter sockets. Also I had a anderson plug fitted to connect a solar panel later on.

All the bits except for the KEMO have been purchased from a local battery world franchise, all including installation I paid about $1200 for the lot, I thought that was a good deal,

My wife and I went camping the other week, using 1w LED lights in the canopy and a 40l Weaco fridge we got about 2 days out of it before the switch cut the power off, still plenty left for lights.
Hope that helps a bit, I decided to go to someone and get it fitted, power is a weird thing for me, and these guys seemed to know what they are talking about.

Have a great Sunday
