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”.
