Lithium Battery Upgrade for Winnebago Revel 4x4 from Agile Off Road RELiON Battery & Victron Energy


Agile Off Road proudly presents our Lithium battery system upgrade for the Mercedes Sprinter-based Winnebago Revel 4x4 RV!

Agile Off Road proudly presents our Lithium battery system upgrade for the Mercedes Sprinter-based Winnebago Revel 4×4 RV! This complete battery & charging system replacement is the first near-drop-in solution of its kind for the Revel platform. Now available for 2018, 2019 & 2020 model year Winnebago Revel 4×4 RVs.

Why upgrade your Revel to Lithium?

A lithium battery’s biggest advantage is the ability to use nearly 100% of its battery capacity in all conditions. The (3) RELiON RB 100-LT batteries in our kit supply 300 usable Amp-hours of power. AGM batteries on the other hand can only use up to 50% of their capacity before risking permanent damage. A 300 AMP hour AGM system will only supply 150 amp-hours of power before requiring a charge. In freezing temperatures usable AGM amp hours are halved again.

With RELiON’s low-temperature batteries, all 300 Amp-hours are on-tap if you need them even in weather as cold as -4° F. However, for the sake of longevity, it’s recommended you do not regularly deplete the batteries beyond 10% capacity. Worry not, with our system there’s no need to be a battery nanny. We’ve programmed the Victron Smart battery controller warning alarms to sound at 20% capacity. Should you drain them beyond that, the batteries have a built-in safety shut off at 8v (or if 1 of 4 cells internal cells reach 2v) to prevent completely killing them.

Lithium batteries also boast a tremendous advantage when it comes to lifespan. 10 years for lithium verses 3-5 for AGM. Or 7000 vs. 600 if we’re counting charge cycles. Winnebago concurs as they’re all-in on lithium too! The 2021 Revel 4×4 is equipped from the factory with a 250 Amp-hour lithium house battery system.

That’s a lot of blue boxes. Here’s the non-technical explanation of what they all do.

Victron equipment allows us to create a Bluetooth powered smart network for your entire battery charging & monitoring system. Through the VictronConnect app we’ve set every parameter of the system for optimal performance and safety. Each of the chargers is in constant communication with the battery sense & monitor. Accurate, live-updating charging, consumption & remaining power metrics are available at a glance.

  • 300 Amp hours of RELiON lithium power
  • Victron Smart Charging & Power Management system with Bluetooth
    • 60+ Amp charging from the alternator with Orion DC chargers
    • MPPT Solar Charge Controller ensures optimum charging in all conditions
    • Battery Sense provides constant voltage & temperature measurements to optimize charging algorithms
    • Smart Battery monitor takes the guesswork out of boondocking with accurate battery life display
  • Minimally invasive battery replacement. Reuses factory locations.
  • Starting at $7600 installed!

Are lithium batteries okay outside?

In the interest of making our kit as minimally-invasive and affordable as possible, we’ve elected to mount the lithium batteries in the factory Revel locations. And despite what you may read on the internet, that’s okay! First, let’s address the cold elephant in the room. Winter camping excursions won’t be put on ice on account of the batteries. RELiON’s RB100-LT batteries (low-temperature) work well below freezing, capable of safe charge & discharge at -4° Fahrenheit. Cold weather operation is made possible by its state-of-the-art non-parasitic battery heating system. An internal heating system means no need for battery blankets. And because the battery’s warmer only accepts power from an external source (solar, shore, engine battery via the alternator) it will never consume itself to charge.

Agile, RELiON & Victron have your back!

Convenience, safety & serviceability were at the forefront of our minds during this kit’s design. So was Revel owner feedback. Easy to access breakers and battery isolators were added to allow for simplified service.

We’re really confident in this kit. After months of field testing in all weather extremes, our beta testers can’t stop raving about it. However, if issues should ever arise, know that Agile, Victron & RELiON confidently standing behind you. Our partnership with RELiON means our Revel lithium upgrade customers are covered by a 7-year nationwide warranty on batteries. Service and repairs are available to owners at any RELiON dealer in the country. All Victron components are covered for 5-years.

What is the cost to upgrade a Winnebago Revel to lithium? How long does installation take?

The Revel lithium battery upgrade takes a full day to install. However, customers should plan to leave their vehicles for 2 days to allow for testing and other upgrades. The installed price for the Agile Off Road Winnebago Revel lithium battery system upgrade is $6999.

After upgrading from AGM batteries to a lithium system, the bottleneck of the house battery system now becomes solar charging capability. Worry not, Agile has a solution for that too! A 115-Watt solar panel add-on kit made specifically for the Revel roof rack on the way! More details coming soon. #smarterthandirt
