Are lithium iron phosphate batteries better than lead-acid batteries?
Lithium Iron Phosphate batteries offer several advantages over traditional lead-acid batteries that were commonly used in solar storage. Some of the advantages are: 1. High Energy Density LiFePO4 batteries have a higher energy density than lead-acid batteries. This means that they can store more energy in a smaller and lighter package.
Why should you use lithium iron phosphate batteries?
Additionally, lithium iron phosphate batteries can be stored for longer periods of time without degrading. The longer life cycle helps in solar power setups in particular, where installation is costly and replacing batteries disrupts the entire electrical system of the building.
Are lithium phosphate batteries good for the environment?
The longer lifespan of lithium iron phosphate batteries naturally makes them better for the earth. Manufacturing new batteries takes energy and resources, so the longer they last, the lower the overall carbon footprint becomes. Additionally, the metal oxides in lithium-ion batteries have the dangerous potential to leach out into the environment.
