Choose the Right Battery for Your Needs

It’s important to choose the right battery to suit its intended application. Deep Cycle Systems are the best people to talk to when you are looking for sound advice on your power requirements.  Whether you need a battery for a boat, camper van, a camper trailer, motor home or 4WD vehicle, we will have the best battery solution for you.

You may be looking for a 40 amp hour deep cycle battery, but this may not be the right capacity for its intended use. You need to make sure that there is sufficient battery capacity (Amp Hours) to power the equipment you intend to use. A 40 amp hour deep cycle battery may not be powerful enough, and it may be better to use a 75 amp hour deep cycle battery or even a 100 amp hour deep cycle battery to ensure that you have the right battery power when you need it. Our range of deep cycle batteries deliver safe lithium phosphate energy storage in a similar size to traditional lead-acid batteries. Upgrading to one of our DCS lithium batteries is a simple task, and you will be getting a battery with six times the battery life and less than half the weight of a conventional lead-acid battery.

As well as 75 amp hour and 100 amp hour deep cycle batteries, we also have 200 amp hour deep cycle batteries and a 150 amp hour dual battery setup.
