Long Term Test | Lithium Ion Motorcycle Batteries

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”.

Crippling Lithium-Ion Battery Flaw Revealed

The first step to solving a problem is diagnosing it, and in this case, a huge step was taken for electric vehicles.

Researchers at Ohio State University discovered that in lithium-ion batteries, lithium-ions accumulate inside a sheet of copper known as the current collector. Lithium-ions should not permanently accumulate on the current collector like this, as they are necessary for battery function, therefore this decreases battery performance, as there will be less lithium-ions available.

67-Pound Carbon Fiber Electric Motorcycle Revealed In Norway

While electric cars are stumbling, electric motorcycles are finding more and more fans in the marketplace thanks to improved performance and generous subsidies. Brands like Brammo and Zero Motorcycles here in America are making a name for electric motorcycles. Over in Norway however, a group of 5 college students have revealed a carbon-fiber electric motorcycle that they plan to build and sell. And on paper, this 67 pound, 94 horsepower motorcycle sounds like some serious competition.
