Lithium iron phosphate (LiFePO4) 12V batteries are replacing traditional AGM batteries as auxiliary power sources in camper vans, motorhomes and boats. Compared to AGM, they offer greater usable capacity, lower weight and longer service life. When choosing a battery, users should consider actual power consumption, the battery management system (BMS) and compatibility with chargers, alternators and solar panels. Brands such as Victron Energyⓘ, Pylontech and BYD have helped build trust in this technology.
