BigBattery 48V 4X EAGLE 2 Kit — High-Capacity Lithium Upgrade for 48 V Systems Upgrade your 48-volt platform with a ready-to-install bundle of four high-performance LiFePO₄ modules, delivering ~6.52 kWh of usable energy. Ideal for golf carts, utility vehicles, RVs, off-grid setups, and other 48 V systems where extended range and reliability matter. Why This Kit Delivers Value Massive capacity upgrade — With four modules each rated at 1.63 kWh (~32 Ah), the total system offers ~6.52 kWh of energy (128 Ah at a 48 V nominal system) which far surpasses many older lead-acid battery setups. Drop-in form-factor — The EAGLE 2 modules use the GC2 / T-105 style tray footprint, making them compatible with many existing 48 V vehicle battery banks without requiring major tray modifications. Premium chemistry & smarter performance — Built with Tier-1 LiFePO₄ (lithium iron phosphate) cells for superior cycle life, stability, and safety compared to traditional batteries. Built for all climates — IP67 / NEMA 6 rated enclosure protects from dust and water. Built-in self-heating enables cold-weather charging and operation down to -20 °C (-4 °F). Smart features & monitoring — Includes LED state-of-charge indicator, CANbus communications support, and capacity meter for remote monitoring of battery status. Scalable & future-ready — Although the kit provides high capacity up-front, modules support parallel expansion (up to 10 of these modules) for larger systems. Ideal Applications & Selling Angles Golf carts, utility & service vehicles — Replace ageing lead-acid banks to benefit from lighter weight, longer use, less maintenance, and more runtime. RV / Camper / Off-Grid Power Banks — Use this kit for 48 V house banks or mobile systems needing high capacity and reliability. UTVs, LSVs, 48 V industrial equipment — The modular design fits inside many existing bays while delivering modern lithium performance. Seasonal or harsh-condition use — Built for cold, dust, wet conditions, thanks to self-heating and high protection rating. Future-proof installations — Start with this kit now and expand later without replacing the core system. If you’re looking for a smart, high-capacity lithium upgrade for your 48 V system, the BigBattery 48 V 4× EAGLE 2 Kit checks the boxes: 6.52 kWh capacity, premium chemistry, plug-in compatibility, rugged build, smart monitoring, and scalability. It’s designed for real-world use where runtime, reliability and performance matter.
