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.”
