I need a battery to keep the free solar energy from the Sun.
To assist with how much my electricity needs I have I could call Aaron Bird from www.birdelectricalcontracting.com.au
I have purchased a 100AH Deep Cycle AGM Battery to begin with. These type of batteries are quite expensive.
This should run the 12 volt fridge and charge our phones while camping.
"Batteries plus" has a good range and I went with a good China brand called Ritar. It represents value for money.
Be sure to buy a AGM battery as normal wet cell batteries are designed for a quick crank of the car engine not a contiunal drain of amps over a long period. Please read up on internet about AGM. Also never let it drain over 50 percent of charge otherwise you battery will not last very long.
