Our base level 12V Van/RV RZBK System weighs less than 85(lbs) and the RZBK’s razor thin casing means you can hide this system away wherever you need. Plus, if you upgrade to our 2, 3, or 4 RZBK System, you’ll be saving even more weight and space compared to the lead acid equivalent.

Just one included RZBK Battery Pack is equivalent to (3) 12V Lead-Acid Batteries! This is the world’s thinnest, power-dense pack designed specifically for a small footprint & high-power applications. With this system, you will be able to power virtually anything and everything you wish in (and around) your Van or RV. This unit is compatible with all 12V Solar Panels allowing you to create a truly off-grid solution for boondocking. 

The AIMS Power 2000 Watt Pure Sine Low Frequency Inverter with built-in battery charger and transfer switch is perfect for moderate sized RVs, campsites, tailgating parties, solar systems, and much more. It will also charge your battery seamlessly when connected to shore power.

At BigBattery, safety is our top priority. Our RZBK (LFP) Battery Packs use ultra-safe LFP cells that can be fully punctured and still not emit fumes or catch fire, and have “Quad-Safety Redundancy” built into every pack. These packs include a built-in BMS, Thermal Management System, Automatic Thermal Protection and 250A Breaker making them the safest batteries you could possibly use in your rig. The battery and inverter included in this kit come with LED Voltage Displays to easily monitor your system.

With 2-3X More Power at 1/3rd the weight & size, this solution was specifically designed for your Camper Vans and RVs. Our system requires Zero Maintenance with batteries guaranteed to last well over 10+ Years! This compact system will save you space, time, weight, fuel, money and the headache of maintenance.
