Now we are going to start getting more technical. How do you connect a second battery to your car? ![]() You can get wiring and circuits configured to be able to charge your battery box while driving, so have this benefit without having to install a second battery permanently. Many people use a battery box and store it in the car while camping, then pull it out when the car is in normal use. If you do not have space, or don’t want to permanently mount a second battery, there are other things you can do. However, if you have a wagon-style 4wd or any other vehicle, you will need to find a way to store it in the boot area. Some manufacturers have even manufactured systems that can be mounted behind the seats in dual-cab utes. If you have a ute, then it is easy to find a spot on your tray or under your canopy to mount your second battery and associated equipment. Some vehicles have enough space for the second battery to be mounted inside the engine bay, but for the majority of vehicles, it will need to be mounted elsewhere. Though this may help to charge your second battery, this does not stop your primary battery from getting drained and becoming flat.ĭual battery systems have special wiring and components then ensure the power flows in the right direction, and can only be used in certain ways.įor example, they prevent the main battery power from being used for the camping appliances and vice versa. ![]() In a dual battery setup, the primary battery will always be designated for car purposes (starter motor, etc.), and the second battery will always be used for your other camping needs (fridges, fans, phones, hot water system).īut it is not as simple as adding a second battery and connecting it to your main battery. The second battery is not designed to be a ‘backup’ for your primary battery if you happen to draw too much power. This battery is then used to power all your camping devices and appliances, instead of your primary battery, which needs to be preserved for your vehicle starter motor and computer, etc. It includes an additional battery added to your vehicle, which is charged while you are driving around. What is a dual battery setup?Ī dual battery setup is a way of setting up your car, so you have increased onboard power available for your camping appliances (fridge, hot water heater, phone charging, etc.), without using and potentially flattening your main car battery. There are a lot of different things to explain about dual battery systems, so throughout this article, we’ll start with the very basics and work our way through to more complicated issues. To prevent this from happening, you can install a dual battery setup to give you the extra power you need while making sure you can always start your car when needed. ![]() No one wants to be stranded in the outback with a flat battery, as you don’t know how long it might be until someone comes along to give you a jump start. Your car battery is a great source of 12v power, but if you use too much of your car’s battery power, then you won’t be able to start your car the next day. What will happen if you use too much of your car’s battery power? The number of appliances people are taking camping these days is growing, and as a result, so is the need for 12v electricity storage. What kind of battery do I need to use for my second battery?Ī dual battery system, or auxiliary battery setup, is a great way to increase the amount of battery storage you have with you without carrying and charging additional portable batteries or battery boxes. ![]()
