Lithium Batteries (LiFePO4)
Lithium iron phosphate batteries that have largely replaced lead-acid in modern truck campers. LiFePO4 batteries weigh about half as much as equivalent lead-acid, can be discharged to 80-100% of capacity (vs 50% for lead-acid), last 3,000-5,000 cycles, and charge significantly faster from solar. The upfront cost is 3-4x higher, but the total cost of ownership is lower over time. A 200Ah lithium bank provides usable power equivalent to 400Ah of lead-acid.
