Why RV Owners Choose Epoch Lithium

Lilthium batteries are quickly becoming the standard for RVers, offering more capacity and freedom. Ditch the weight, voltage sag, and short cycle life of lead-acid and AGM batteries. Epoch’s LiFePO4 Essentials line adds modern features RVers actually use: built-in heating for cold-weather charging, Bluetooth monitoring, and a smart BMS for safety and longevity. We don’t just sell and install Epoch lithium batteries, we run them in our RV.

Core benefits you’ll enjoy with an Epoch Lithium System:

  • Double the Capacity per Ah: Lead Acid / AGM batteries can only be discharged to 50% before damage occurs. Not so so with lithium. Use an Epoch battery to it’s full potential.

  • Charge safely below freezing thanks to internal self-heating.

  • Check battery health on your phone (iOS/Android Bluetooth app).

  • Smart BMS protections (over/under-voltage, temp, over-current/short-circuit).

  • Long life: rated for ~4,000+ cycles (10× lead-acid typical).

  • Strong warranty: 11-year manufacturer coverage.

Battery system with red and black cables, electronic components, and labels, installed in a vehicle or device for energy management.

“I run two Epoch 460Ah Essentials in my 2022 Airstream Globetrotter 27FTB. This allows days of power, even running our air conditioners from our batteries and 3000W inverter.

We not only use Epochs personally, but Pagosa Supply Co is a trusted source for lithium upgrades and authorized dealer for Epoch Lithium.

While we routinely outfit Leisure Travel Vans and Airstreams, any RV brand / category is a perfect candidate for an Epoch 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.

What makes Epoch Essentials / Pro / Elite Series Lithium Batteries a Great Choice for RVs?

The Epoch lithium lineup offers two clear tiers: Essentials for maximum value and Pro/Elite for maximum performance. In the 300Ah class, the Essentials model provides strong capacity and all core features—Bluetooth, heating, and smart BMS—while the 300 Pro steps up with higher continuous discharge, stronger surge capability, and native Victron CAN integration for advanced systems.

In the 460Ah class, the Essentials delivers the best cost-per-kWh with ample power for most RV setups, while the 460 Elite adds a fully waterproof IP67 enclosure, higher current limits, and full Victron communications for demanding inverter loads and harsh environments. In short: Essentials = best value and capacity; Pro/Elite = premium performance, integration, and ruggedization.

For Single Battery use with a 3000W inverter, choose the Epoch 300Pro (460 Elite can, but limited to 2800W continuous, so limited) Or double up the Essentials 300 / 460 or Elite 460 for MAX power capability.

  • Heated charging for sub-zero conditions—no more winter charging anxiety.

  • Bluetooth app for real-time SOC, voltage, temps, and cycle counts.

  • Smart BMS with temp, current, and voltage safeguards.

  • Long cycle life & low maintenance vs. AGM/lead-acid.

  • Backed by an 11-year warranty from Epoch.

Running Air Conditioning on Lithium Batteries Requires adding a Soft Start / Easy Start to Your RV Air Conditioner

Your RV air conditioner is designed to be powered from a 30 or 50 amp power source. This is because compressor motors are connected in a way that lets them draw as much power as required to get up to speed quickly.

Because of this design, compressor motors require a massive current surge when they start that is too much to handle for a 15 or 20 amp breaker or the RV’s inverter, but there is a solution.

Soft Starts / Easy Starts effectively limits the inrush current and so improves the stability of the power supply and reduces transient voltage drops that may affect or break down other loads. This eliminates the need for excessive power supply which results in reduced equipment costs, investment in power supply capacity, charge meter, circuit breaker, and power wireline capacity, and it extends the service life of the motor or compressor.

Soft Start Guide
Epoch Batteries — Frequently Asked Questions
Are Epoch lithium batteries safe in cold weather?
Yes — internal heaters automatically kick in and allow safe charging below freezing. The BMS manages temperature limits so you never have to worry.
Can I monitor from my phone?
Absolutely. The Epoch Bluetooth app (iOS & Android) shows real-time SOC, voltage, current, temperature, cycle count, and more.
How long do they last compared to AGM?
Epoch Essentials are rated for 4,000+ cycles to 100 % DOD — dramatically outlasting typical AGM batteries (usually 500–800 cycles at 50 % DOD).
Can an Epoch battery run my RV air conditioner?
Yes — with the right setup.

You need a 3,000 W inverter, proper heavy-gauge cabling, correct fusing, and the right number of batteries:
300 Pro Series → one battery runs a 3,000 W inverter no problem
Essential Series → minimum of two batteries required
460 Elite → two recommended, but one can run a 3,000 W inverter as long as you never exceed ~2,800 W continuous
Do you sell batteries for DIY?
Yes! We stock the 300Ah and 460Ah models for DIY builds and provide recommended charge profiles, wiring diagrams, and support. We also offer full professional installs if you prefer.
What about warranty?
Epoch backs every battery with an industry-leading 11-year manufacturer warranty. We handle registration for you and make sure your system is set up correctly from day one.
