Epoch Lithium Batteries:
Half the Weight, Twice the Power than AGM / Lead Acid
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.
“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.”

Which Epoch battery fits your travel style?
12V 300Ah Essentials — Compact Powerhouse
Perfect for couples and weekenders who want to run a residential-style fridge, lights, fans, laptops, CPAP, and occasional microwave use with confidence. Heated & Bluetooth-enabled, with a robust BMS and multi-year lifespan. Add a double 300Ah, 30000W inverter setup and enjoy seriously long air conditioner run times!
Great for: Airstream single-battery bays, compact Class B/Small Class C, towables needing big capacity without a full electrical redesign. Download Spec Sheet
Typical add-ons: 2000–3000W inverter/charger, DC-DC alternator charger, 400–800W solar. (For 3000W inverters, minimum of two 300Ah Essentials is required)
12V 460Ah Essentials (Group 8D) — Long-range, low-anxiety power
For boondockers and full-timers who want to run Air Conditioning, induction, espresso machines, Starlink, workstations, and longer microwave/air-fryer sessions—without babysitting State of Charge. Heated & Bluetooth-enabled, with extended cycle life and serious usable kWh.
Great for: Airstream dual-battery upgrades (like our Globetrotter setup), Leisure Travel Vans Unity/Wonder, and any rig aiming for generator-free camping.
Typical add-ons: 3000W hybrid inverter/charger, high-output alternator/DC-DC, 800W–1.2kW solar, soft-start AC strategies. Download Spec Sheet
12V 460 Elite: waterproof, winter-ready, Victron-smart
The Epoch 12V 460Ah V2 Elite is a serious upgrade for boondockers and full-timers: IP67 waterproof/dustproof, internal heating for sub-zero charging, Bluetooth health monitoring, and Victron CANBUS communications for clean, native integration with Cerbo GX and the Victron ecosystem. It’s the big-capacity, low-anxiety bank RV owners want when they’re done babysitting batteries. It’s ideal for:
IP67-rated enclosure for dust & water resistance—confidence in storms, washdowns, and damp bays
Victron communications (CANBUS) for direct BMS ↔ Victron GX data—streamlined monitoring & control. Download Spec Sheet
Quick comparison: Epoch Essentials 300Ah vs 460Ah
300Ah: smaller footprint, weekend trips, moderate AC loads
460Ah: maximum runtime, induction/espresso/Starlink, light AC with smart strategies
Cold-weather charging: both include internal heating.
App & BMS: both include Bluetooth monitoring + smart BMS.
Cycle life & warranty: 4,000+ cycles, 11-year manufacturer warranty.
What makes Epoch Essentials Lithium Batteries stand out?
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.
Epoch 460Ah: Essentials vs Elite (what’s different + why it matters)
Both give you massive 12 V capacity with internal heating and Bluetooth. The Elite 460Ah (V2) steps up with a sealed IP67 enclosure (dust/water resistance) and native Victron CAN communications for clean integration with Cerbo GX and the broader Victron ecosystem. It also allows higher charge and discharge currents, which matters for heavy inverter loads and faster recharge windows. Choose Essentials if you want maximum kWh at the best value; choose Elite if you want waterproofing + Victron-native comms + higher current headroom.
Side-by-side (key electrical & hardware differences)
Ingress Protection
Essentials 460Ah: IP21 (indoor/protected bay).
Elite 460Ah (V2): IP67 (dust-tight, water resistant). Better for damp bays, washdowns, or marine-adjacent installs.
Communications / Victron integration
Essentials 460Ah: Bluetooth app for SOC/health; generally no native Victron CAN (easily add a shunt or gauge for detailed system data).
Elite 460Ah (V2): Bluetooth + CAN (Victron comms) for direct BMS↔Victron GX data—cleaner installs and more accurate SOC.
Max continuous discharge (amps)
Essentials 460Ah: 200 A continuous (400 A 10 s). Recommend dual batteries for 3 kW inverter setups.
Elite 460Ah (V2): 300 A continuous (up to 500 A 10 s / 1200 A 1 s). Extra headroom for big surge loads.
Max charge current
Essentials 460Ah: 200 A max (400 A 10 s)
Elite 460Ah (V2): 230 A max (300 A 10 s)
Size/weight (approx., 8D class)
Essentials: ~20.55” × 8.58” × 9.45”; ~ 83.78 lbs / 38 kg.
Elite: ~20.83” × 8.62” × 11.54”; ~ 88 lbs / 40 kg.
