It's time for a new battery in my '05 R1200GS. The current (cheap) one is dying after less than a year (you get what you pay for...). I've read various threads on the new lithium batteries and the "best agm battery" thread. I was just wondering if any of y'all have any real world experience with a LiFePo/Shorai battery in a GS, or have switched between an AGM & lithium. Thanks.
