Why RV Owners Choose Lithionics Lithium

When it comes to premium lithium power for RVs, Lithionics is the gold standard. Their cutting-edge NeverDie® Battery Management System, higher allowable discharge rates, and US-based engineering make these batteries the go-to choice for RVers who want maximum reliability, safety, efficiency, and lifespan.

At Pagosa Supply Co, we’ve run Lithionics systems in our own rigs—including the legendary 320Ah GTX battery that changed the way we travel. Whether you're looking to run high-demand appliances, power your A/C off-grid, or finally ditch generator life forever, Lithionics gives you the freedom to roam.

Below, explore the most popular Lithionics batteries used in RVs:

Perfect for Airstream, Leisure Travel Vans, Storyteller, Revel, custom builds, and any RV owner ready to step into the world of true high-performance lithium

Lithionics 320Ah: The Gold Standard

When we swapped our factory batteries and 2000W Inverter for the Lithionics 320Ah and 3000W inverter, it changed the way that Janet and I RVed. No more depending upon a power pole, but pure freedom.

Now Pagosa Supply Co is an Authorized Lithionics dealer, offering batteries for DIYers or custom installs for any RV.

While we routinely outfit Leisure Travel Vans and Airstreams, any RV brand / category is a perfect candidate for an Lithionics system. Enjoy new found freedom with safe and rock-solid results.”

Real-World RV Power Calculator: Solar, Lithium, and Daily Loads

No more hoping your batteries last “a few days.” These live calculators and real-world charts (built from thousands of actual boondocking rigs) instantly tell you:

  • How long your lithium bank really lasts with your daily usage
  • Exactly how many watt-hours your roof solar actually delivers (hint: it’s never “panel watts × 8”)
  • What a normal boondocking day costs in power (most people use 1,300–1,600 Wh)
  • How many nights you can truly stay out with (or without) solar

Default numbers are set to what 90 % of experienced boondockers see in the real world — just click any panel below and play with your own numbers. Everything updates instantly.

How Much Solar Do You Actually Harvest?

RV Roof Solar Reality: — Even in ideal sun you’ll often get only ~3-5 full-sun-equivalent hours/day — under clouds or poor orientation it can drop much lower. Use this data for the solar section in the boondocking calculator below.

Lithionics Batteries — Frequently Asked Questions
Are Lithionics batteries worth the premium price?
Yes — for full-time RVers and serious van builders, they are the gold standard. You get NeverDie® BMS with engine-cranking reserve, true RV-C CANbus integration (works natively with Victron Cerbo), IP66 fully sealed case, internal shutdown separator, and proven 10+ year reliability in high-end coaches.
Can a single 320Ah run a 3000W inverter + air conditioner?
Absolutely. The 320Ah GTX is rated for 250A continuous (≈3,200W). Most 13.5K BTU roof A/Cs draw 110–140A running and under 220A at startup — a single 320Ah handles that all day with margin.
What’s the difference between Boss 302 and 320Ah GTX?
Boss 302 (305Ah) → 200A continuous
320Ah GTX → 250A continuous + 4,096 Wh (vs 3,904 Wh)

The 320Ah is the upgraded model specifically made for single-battery 3000W inverter builds.
Can I mix Lithionics with Epoch, Battle Born, or LiTime?
No. Lithionics uses a proprietary BMS protocol and balancing method. Only parallel identical Lithionics batteries together.
What is the warranty?
5-year full replacement (non pro-rated) when purchased through an authorized dealer like Pagosa Supply. We handle all registration and support.
Do you offer professional installation?
Yes! Full turn-key installation at our Coppell, TX headquarters or mobile install teams nationwide. Most Lithionics upgrades are completed in one day.
