One decision our clients have to make when setting up their RVs with solar power is what kind of battery bank they want. Lifeline AGM batteries are very popular for this type of application, but we also offer Lithium batteries, which are the latest and greatest battery technology. For this client we installed an 800Ah 12V Lifeline AGM battery bank. A comparable lithium system would have cost over $6000, while this client paid around $2200 for their AGMs. This is a very powerful system for someone who doesn’t want to spend the additional money on a Lithium system.
