Comparing the Lithionics and Volta RV Battery Systems from Winnebago

Two Great Systems, With Some Notable Differences

Image Caption:


Lithium battery systems in RVs are fairly new, but they’re quickly becoming more commonplace, and Winnebago offers two different systems for campers to use. They are the Lithionics and the Volta systems.  

As James from the Fit RV explains in this video, both systems work. Both are quality options available on the market right now. The question is, which should you choose. Well, while these systems are both good, they do have some differences. James explains those differences clearly in the video above, but let’s take a closer look at the highlights below.  


  • What James calls Lithium-Iron battery chemistry 
  • Great for Safety and Lifespan 
  • 12-volt nominal power 
  • Total battery capacity: 8,400 watt-hours 
  • 3.8 hours to charge 
  • 2,000-watt output, 4,000-watt surge 


  • What James calls NMC battery chemistry 
  • Great for Specific Energy (energy per unit mass) 
  • 48-volt nominal power 
  • 3 module total battery capacity: 10,109 watt-hours 
  • 4 module total battery capacity: 13,479 watt-hours 
  • 2.5 hours to charge 
  • 3,600-watt output, 6,000-watt surge 

The bottom line is that both batteries can provide you with all the power you need to run your RV and they will last thousands of cycles (years and years of use). Both will also provide you with plenty of power, and in most cases more power than you really need. It comes down to preference and what you feel your needs are for a reserve of battery power.
