Agape Off-Grid has several 12V deep cycle batteries for sale to power your off grid system. Our standard lithium 12V batteries sizes range between 50Ah and 200Ah and have a low self-discharge rate and come with a three-year manufacturer’s warranty. We also carry AGM heavy-duty deep cycle batteries that offer 20 percent more charge/discharge cycles and have a five-year warranty. Each one uses the same amount of space as your current 12V cells, making it easy to switch. Add a voltmeter, fuse kits, jumper cables and other accessories at check-out and you’ll be ready to hook up your new power system.
