Battery
Your battery is the lifeline of your car, providing all the electrical power your car needs to relay information from sensors to ECU. Your alternator constantly keeps the battery charged ensuring that you are never without power. Battery technology has evolved to have many lightweight lithium options that last quite a long time, weigh next to nothing, and are compact enough to fit wherever you may desire. Though not the sexiest mod, upgrading your battery can result in 20+ pounds of weight savings and create a smoother electrical system
