Fiskers Claims Against A123 Systems Cut By 89%

April 10th, 2013 | by Nicholas Brown

Fisker Automotive made claims of $140 million against A123 Systems (now called B456 Systems. They moved onto the next letter in the alphabet and used the three numbers after 123) because of the rejection of its supply agreement and alleged breach of warranty obligations. The claims were $91.2 million for damages caused by rejection of its supply agreement, and $48.7 million for a breach of warranty obligations. But most of these claims were rejected


Long Term Test | Lithium Ion Motorcycle Batteries

February 5th, 2013 | by Susanna Schick

Well, the Skyrich is in that special battery home in the sky now, ready to become fertilizer (for real) thanks to the lack of any battery management system (BMS). I ran this battery on my 2009 Yamaha R1 since May 2011, (first reported here) putting about 12,500 miles of mostly city riding on it. So while Skyrich advertises that the battery lasts 2,000 cycles, as opposed to the 3-500 lead acid batteries can take, I only found it to last about 2.5 times as long as the lead acid my bike came with. I didn't count the cycles, I counted the years. The stock battery lasted 1 year. The Skyrich was starting to get weak this winter, but I didn't do the research until after it died. It turns out that with liIon batteries, when it's cold you actually heat it up by turning the key and letting it power the lights for a minute. I did find that although it wouldn't crank on the first try in the cold, it would eventually crank. Unlike lead acid, lithium batteries get stronger as you use them, they "warm up"
