Phuc Lam from Shorai Inc, and also an avid motorcyclist, explains lithium batteries in this episode.

Since 2010, Shorai has been the maker of lithium iron phosphate batteries. Shorai LFX batteries are up to 80 percent lighter than equal performance lead acid batteries, which can mean saving anywhere from 2 to 20 pounds, depending what kind of bike you ride. They operate at a higher voltage range and maintain a higher voltage level during cranking, which means your motorcycle starts more quickly.
