The ultimate heavy-duty off-grid energy vault. This premium 2-pack bundle delivers massive standalone capacity, smart low-temperature protection, and Grade-A lithium cells to build an uncompromising power system for your RV, overland rig, or marine vessel.
When you are living full-time on the move or building an elite off-grid solar array, standard small-capacity batteries just won't cut it. Connecting multiple tiny batteries creates complex wiring bottlenecks and balance issues. The Nomad Charge 12.8V 280Ah Deep Cycle LiFePO4 Battery 2-Pack solves this by providing massive, foundational power capacity in two high-efficiency blocks. Built with top-tier Grade-A cells, each battery is engineered to deliver between 4,000 and 15,000 deep cycles, maintaining an outstanding 80%+ Depth of Discharge (DOD) even after clearing 4,000 full cycles.
Weighing in at 113.54 lbs, this high-performance lithium pack delivers 2 to 3 times the energy density of traditional lead-acid banks while slashing total footprint weight and offering an extensive 10-year service life. To tackle unpredictable backcountry weather, each battery features a cutting-edge low-temperature protection network managed by an internal Smart BMS (Battery Management System). It automatically stops discharging below 5°F (-15°C) and charging below 14°F (-10°C) to lock down cell stability in freezing climates. Whether you are running complex dual-zone galleys, heavy inverter loads, or off-grid climate systems, this bundle handles the demand with total peace of mind. Please note: these deep-cycle batteries are built for standby house power arrays and are not intended for vehicle engine starting.
In alignment with our core brand values at Boundless Trek, we emphasize reusable, ultra-efficient energy systems that eliminate dependance on disposable components. To keep our operational footprint entirely sustainable, we utilize a 100% digital administrative workflow to eliminate physical paper waste. Plus, we proudly pledge 10% of our retail profits directly to environmental conservation organizations to keep our public lands and trails pristine for future generations.
Why It’s the Ultimate Power System Anchor:
-
Massive 280Ah Standalone Core: Provides incredible capacity within a clean, streamlined footprint, cutting out the messy wiring clutter and structural strain of standard multi-battery parallel daisy chains.
-
Premium Grade-A Cell Lifecycle: Delivers an exceptional 4,000 to 15,000 deep cycles, outperforming traditional lead-acid batteries that degrade rapidly after only a few hundred runs.
-
Incredible Energy Density: Swapping out old toxic banks reveals immediate benefits, providing 2 to 3 times the usable energy density alongside a robust 10-year service lifetime.
-
Automated Freeze Defenses: Specially calibrated to survive harsh, sub-zero environments, the smart internal sensor grid automatically cuts off charging below 14°F (-10°C) and halts discharging below 5°F (-15°C) to guard cell chemistry.
-
Integrated High-Current BMS: Outfitted with an advanced Battery Management System that shields your rolling infrastructure from overcharging, short circuits, overcurrent surges, and overheating.
-
10% Conservation Pledge: Your power upgrades directly support public lands. A portion of every purchase goes straight back into maintaining wilderness trails and protecting national forests.
