Features to know about

Know Your Power, Wherever the Road Takes You

Before you roll out on your next big adventure, you want to feel prepared, not left guessing if your battery will hold up when you need it most. With built-in Bluetooth, you can check your battery's health, charge, and performance right from your phone. If you're parked in the pines, docked at the lake, or boondocking off the beaten path, you stay in control - no more crawling into storage compartments or second-guessing your setup.

Built to Outlast Ordinary Batteries

Traditional lead-acid, AGM, and gel batteries can wear down after just a few seasons of hard use. The Alpha 1 Pro is built for the long haul, delivering over 7,000 cycles and guided by a smart BMS that shields your battery from overcharging, deep discharging, and extreme temperatures. When cold weather hits, the built-in self-heating system activates at 41°F and keeps working until the battery is warmed above 50°F. This helps prevent freezing temperatures from cutting your trip short or shortening battery life, so you get worry-free power and the freedom to explore even when the forecast turns frosty. Enjoy fewer power interruptions and the confidence that your battery is ready for every season.

Compact, durable, and smart, this battery gives you serious power without the hassle. If you’re upgrading from lead-acid or just want a safe, lightweight lithium option you can monitor from your phone this Alpha Pro is a standout.

See what our Experts say about this Rich Solar Battery

  • Can RV AC Unit be Powered by 12 Volt Battery
    Hey Steve, RV AC units are designed to be powered by AC power and not DC like what a battery like what part # RS74VR provides but if you have a power panel in your RV it will have AC power circuits and it will be wired up so that the panel can draw power from the battery. Does your RV have an AC unit it currently?

  • What Is The Warranty On Rich Solar Panels, Controllers, And Batteries?
    Great question Jim! Don't worry, you won't be wasting any of you money since the Rich Solar lineup is extremely good quality, and is backed by a great warranty. We just had the pleasure of talking to the Rich Solar reps in person (shout out to George) and he explained the warranty and post-purchase support very well. A solar kit like Rich Solar RV Solar Charging Kit w/ 6 Panels - 12V - 1,200 Watts # RS67VR consists of solar panels, controllers, and can be paired with a battery like Rich...

  • Can PowerMax Converters Be Used Without 12V Battery In The Camper?
    Hey Chris! Yes, PowerMax converters like the # PM34VR 45 amp, # PM94VR 55 amp, # PM44VR 60 amp, and # PM84VR 100 amp can supply 12V DC power to your system even if a battery isn’t connected. When plugged into shore power, they’ll convert AC power to 12V DC and run your lights, fans, water pump, and other 12V loads directly via the DC fuse box. That said, without a battery in the system, you won’t have any 12V power once shore power is disconnected. For most RV setups, having a battery...

  • Battery Size When Replacing RV Deep Cycle with Lithium
    Hey Chris, a good place to start with would be what is the amp rating of the current battery you have and then decide if that was adequate or not and go with a similar or higher rated lithium battery. The Rich Solar Alpha part # RS74VR that you referenced is a 100 amp hour battery. I attached a link to all of the lithium batteries we carry as well.

  • How Many Watt Solar Panel For 100ah Lithium Battery In Jayco Popup Camper?
    Hey Henrick, yes I can help you out with finding a good solar panel for the Rich Solar Alpha 1 Pro Lithium Battery # RS74VR. First let's do some quick math based on your electronics: A 12V fridge (60W × 10 hours) = 600Wh LED lights, fan, phone charging = 150Wh Total: ~750Wh per day You’ll need at least 750Wh of solar charging per day just to break even. If you used a 100w kit # RS27VR, you would be helping the battery from discharging as quickly, but it's not going to be enough to keep...

  • How Much Power Can A 100W Solar Panel Put Out On Forest River R Pod?
    Good morning Brianna! On a good sunny day, a 100W panel like the Rich Solar # RS27VR can produce about 30–35 amp-hours of power over 5–6 hours of direct sun. That’s ~6 amps of charge per hour which is enough to recharge a partially depleted 100Ah battery like the Rich Solar Alpha Lithium Battery # RS74VR, run your lights and phone chargers, and top you off for the evening. Its not enough for heavy draws like a DC fridge, TV, or microwave, but for basic weekend use, its plenty. We often...
