But now battery companies spread around the world are working feverishly to invent the breakthrough battery that will change transportation forever. One such company is Mastervolt that has developed a 24 volt lithium ion battery. Weighing in at just 115 lbs., the output is that of four 8Ds. Think of that. A single 115-pound battery functioning as well as four 140-pound batteries--or 560 lbs! Not only that, Mastervolt claims that their battery will last three times longer than the 8D. (Group 8D AGM batteries are powerful 12-volt, 225 to 255 Amp hour, heavy duty, deep cycle batteries costing several hundred dollars and used in large luxury RVs and yachts.)
Though available now only in 24-volt and being marketed to yacht owners, a 12-volt version is in development, which could be a breakthrough for RVers--and especially for boondockers. There is one slight hitch, though. The battery costs $7,500. However, with a smaller 12-volt version, and as demand and manufacturing mass production come together, prices will come down. How far down, is hard to tell, but with competing companies also pushing the same development, it may--hopefully--be sooner rather than later.
