Yes, LiFePO4 (lithium iron phosphate) batteries can be used as starter batteries, offering benefits like lighter weight, longer lifespan, faster charging, and better performance in extreme temperatures compared to traditional lead-acid batteries. However, it is crucial to use a LiFePO4 battery specifically designed for starting applications, as these "cranking" batteries are engineered to deliver the high, fast current required for engine ignition. Attempting to use a deep cycle...
