Description
Massive Energy in an Ultra-Compact Footprint
Storing large energy reserves usually requires bulky, heavy battery banks. Landsion breaks this barrier with an advanced cell density design that delivers over 3 times the energy of a standard 100Ah battery in a frame just slightly larger than a single 12V 100Ah unit.
Weighing only 59.3 lbs (compared to 180+ lbs for equivalent lead-acid capacity), this battery reduces weight on your vehicle or vessel while delivering consistent, stable voltage for heavy inverter loads and high-power appliances.
Key Product Highlights
🔹 Breakthrough Size & Weight Reduction
-
Ultra-Compact Dimensions: Measures just L 12.99″ × W 7.48″ × H 8.50″—making it roughly 40% smaller than competing 12V 300Ah packs.
-
Lightweight Efficiency: Weighs just 59.3 lbs (26.9 kg), allowing for easy handling and significant weight savings in mobile builds.
⚡ High-Output 200A Continuous Discharge
-
Inverter-Ready Output: Built with a continuous 200A discharge BMS, easily handling high-draw 12V inverters, power tools, microwave ovens, and air conditioning units.
-
Stable Power Curve: Holds a flat voltage discharge curve throughout the cycle so your equipment runs at full efficiency until the battery is depleted.
🔌 Flexible Multi-Pack Expansion
-
Scalable Configurations: Supports up to 4 Series (4S) or 4 Parallel (4P) configurations to build custom 24V, 36V, or 48V power banks up to 64.32 kWh total energy.
🛡️ Smart BMS & Extreme Environment Protection
-
5000+ Deep Cycles: Premium LiFePO4 chemistry provides over 10 years of operational life with a 60% lower lifetime cost compared to lead-acid batteries.
-
IP65 Weatherproof Build: Sealed against water, dust, and vibration, making it reliable for rugged marine, off-road, and off-grid environments.
-
Comprehensive BMS Safety: Actively guards against short circuits, overcharging, over-discharging, thermal extremes, and voltage imbalances.
📍 Primary Applications
-
RVs & Overland Camping: Runs onboard AC units, refrigerators, and entertainment gear without generator noise.
-
Off-Grid Solar Arrays: Stores daytime solar energy for remote homes, cabins, and agricultural setups.
-
Marine & Boating: Serves as a lightweight house battery bank with full water and shock resistance.
-
Commercial & Emergency Backup: Powers communication systems, medical gear, and critical lighting during grid outages.
