Introducing the the world's thinnest battery! BigBattery's 12V 1.76 kWh RAZORBACK (RZBK) battery is the thinnest and safest solution for your RVs, APS systems, and other 12V applications. Perfect for your DIY system or to expand your Big Battery 12V RZBK Van and RV System.
More Power and 1/3 the Weight:
Just one included RZBK Battery Pack is equivalent to (3) 12V Lead-Acid Batteries! Weighing only 85 lbs and the RZBK's razor thin casing means you can hide the system away wherever you need. This solution was specifically designed for your Camper Vans and RVs.
You can connect up to 8 of the RZBK Battery Packs in parallel! 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.
10-Year Output Warranty:
Buy with confidence knowing that your battery investment will last for the long-haul.
Safety is Our Top Priority:
The 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.
