Lithium Batteries

While Lithium batteries are certainly the near-term future of renewable energy storage, some technologies are much safer and reliable than others. Planetary Systems has tested and is supplying a version of the Lithium Battery cell, that be Lithium Iron Phosphate (LiFePo4) in a cylindrical cell arrangement and in 12vdc and 24vdc packages with complete battery monitoring and integral safety controls. The batteries have passed crush tests, puncture tests and are UL-1642 rated. We have found them to work very well with Outback Power Systems controls and inverters and have a set here which we have tried to fail, but as yet, this battery has passed every test for a renewable energy home. We feel so strongly about this technology that we have discontinued all sales of any other battery type. These batteries are slightly more expensive than a comparable bank of AGM or GEL batteries and much less expensive than a Nickel-Iron battery with virtually the same cycle life and longevity. For instance, we replaced our 1000ah-24vdc AGM battery with a 260ah pair of 12v Li cells and have never run out of power, never gotten below 35% though you can use 100%, never not had power on even a cloudy day and ALL our charging sources have become about 50% more efficient. The Lithium battery is usually charged before noon on any sunny day and nearly always at 90% by the end of a cloudy day. So we are fully implementing the Lithium battery into all our sales and battery replacement. Oh and they only weight between 29lb and 50lb per cell and there are very few connections to make-almost anyone can install them with a few precautions.
