RV Batteries

For Off-Grid Adventures

Choosing the right RV battery is essential for any off-grid travel setup, whether it is a motorhome, travel trailer, fifth wheel, or camper. Our Full Throttle, Full Force, EGL, and DC Series AGM batteries deliver reliable starting power for motorhome chassis batteries, along with consistent deep-cycle power for the house battery bank that runs your appliances, air conditioners, and electronics. From short weekend warrior trips to full-time RV use, Fullriver gives RV owners the dependable power and long battery life to explore the world while still enjoying the comforts of home.

At Fullriver, we offer a wide range of high-quality RV Batteries.

Full Throttle Series

Each high-performance absorbent glass mat (AGM) battery in the Full Throttle Series is built with high-compression cells and a heavy-duty case for long-lasting performance. With Thin Plate Pure Lead (TPPL) technology, fast charge rates, and a variety of size options, these premium batteries are designed to handle the toughest off-road conditions.

DC Series

DC Series batteries are made of thick plates built with pure virgin lead for unrivaled deep cycle performance. These fast-charging batteries can be mounted horizontally and vertically and no maintenance is required. The DC series are ultra-durable for long-lasting deep cycling power in demanding conditions.

Full Force Series

The Full Force Series offers the same benefits of the Full Throttle series with a budget-friendly price point. These fast-charging batteries feature vibration resistance, multiple installation options, and a tough outer case that prevents leaks or spills.

EGL Series

The environmentally-sustainable Eagle Series batteries have nearly double the lifespan of a traditional golf battery. These batteries are built for high performance in electrical vehicles. By offering drop-in replacement technology, very low internal resistance, and zero-maintenance capabilities, the EGL series sets itself apart.

Reliable Battery Features

Our RV battery solutions are engineered for consistent off-grid performance and long battery life across a wide range of recreational vehicle and motorhome applications. Key Features:

Keep the lights on when there's no hookup in sight: Strong amp-hour and reserve capacity carry your fridge, water pump, lights, and electronics through days of boondocking, then recharge fast when you reach shore power or fire up the solar.
One battery for the house and the start: A pure-lead AGM has the deep cycling stamina to run your living space and the cranking power to turn over the engine.
Sleep next to it without a second thought: The sealed, maintenance-free design has no water to refill and no acid fumes venting into your living space, unlike a flooded battery you'd never want inside the coach.
Built for the miles between campsites: Over-the-partition welds and high-compression cells take the constant vibration of travel days and rough roads that shake ordinary batteries loose.
Set it and forget it for the whole season: Thick pure-lead plates and a sealed case mean long service life with no maintenance, so your power is ready every trip without topping off cells or chasing corrosion at the terminals.

FAQs

What size battery does my RV need?

The right deep-cycle RV battery depends on your rig, your daily amp hours, and whether you need a house battery, a chassis starting battery, or both. Most house battery banks use 12-volt Group 24, 27, or 31 AGM batteries, or pairs of 6-volt GC2 batteries wired in series for greater capacity. Match your group size and voltage, then use our Battery Finder to confirm fit.

Are AGM batteries good for RVs?

Yes. An AGM battery is an excellent choice for RV use and one of the best options for RV owners who want a dependable power source. The sealed absorbent glass mat design needs no regular maintenance, contains no spillable sulfuric acid, and delivers superior performance compared to a traditional lead-acid battery or older flooded lead-acid batteries. Fullriver's premium AGM offers proven, reliable performance and consistent power without the higher upfront cost of lithium-ion batteries or gel batteries.

How do I charge and maintain my RV battery?

Proper charging is the biggest factor in long battery life. Use a quality battery charger or AGM-rated converter rather than a basic trickle charger that may not fully restore a deep-cycle battery after a heavy discharge cycle. A solar panel paired with a quality solar system controller is an excellent choice for keeping your house battery topped off between trips. When storing your RV for an extended period, disconnect the battery to avoid parasitic drain, and check connections in the battery box for corrosion or signs of a short circuit.

Can I replace a single 12-volt RV battery with two 6-volt batteries?

Yes, and many RV owners do. Wiring two 6-volt GC2 deep-cycle batteries in series gives you a 12-volt system with significantly more amp hours than a single Group 24 or 27 12-volt battery, while fitting the same battery box on most rigs. This is one of the most popular upgrades for boondockers, full-timers, and weekend warrior campers who run inverters, air conditioners, or multiple appliances off the house battery bank.

How do AGM RV batteries hold up in extreme temperatures and demanding RV applications?

Fullriver AGM batteries are built for it. The sealed design handles high temperatures, cold mornings, vibration on rough roads, and the deep discharge cycles of regular dry camping. With proper charging, our deep cycle batteries deliver thousands of cycles for golf cart and RV applications alike, giving you superior performance and dependable power on every trip.
