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.”

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.
