Big Battery 48V 3X EAGLE 2 KIT - K0979
2ND GENERATION POWER TAKES FLIGHT! Introducing BigBattery’s all-new 48V 4.89 kWh LiFePO4 3x EAGLE 2 Kit. The EAGLE 2 embodies the reliability and durability you’ve come to expect from BigBattery solutions, packing Tier 1 LFP cells in a compact, GC2 form factor. This energy-dense design allows for effortless installations in your golf cart, utility vehicle, 48V UTV, or 48V LSV. Plus, the EAGLE 2 serves as a mirror-image replacement for any stock T-105 lead-acid battery, allowing you to greatly reduce the total weight of your cart without battery tray modifications, while seeing significant boosts in lifespan, range, and acceleration.
But the EAGLE 2 provides so much more than efficient, long-lasting lithium power storage. This battery comes standard with advanced features that enhance the safety and visibility of your power. Not only does the EAGLE 2 come equipped with an LED capacity meter on the top of the unit, but it also supports CANBus communication protocols, and the EAGLE Kit comes with its own external capacity meter, so you can always monitor the status and performance of your battery system, even while your batteries are tucked away in their battery tray. Plus, the EAGLE 2 features a fully reimagined, IP67-rated casing for comprehensive protection against dust, water, and other contaminants while you’re on the road.
But that’s not all. The EAGLE 2 was designed to support your adventures through every season. Whether you’re hitting the links on a hot summer day, or going boondocking in the middle of winter, the EAGLE 2’s advanced BMS supports a wide temperature operating range, and a self-heating function allows for superior cold weather charging, ensuring your adventures never get cut short due to unreliable power. Quit worrying about your power and get back to making memories with friends and family when you equip your vehicle with the all-new 48V EAGLE 2 from BigBattery.

Q&A
Q: What is the BigBattery 48 V 3× EAGLE 2 KIT (K0979)?
A: A high‑capacity 48 V lithium battery system made of three EAGLE 2 LiFePO₄ modules — designed as a plug‑and‑play replacement or upgrade for 48 V lead‑acid battery banks in golf carts, utility vehicles, RVs, and other 48 V applications.
Q: What is the combined capacity?
A: Three EAGLE 2 modules together form a substantial 48 V battery bank, offering significantly more usable energy and runtime than a single module or comparable lead‑acid pack.
Q: What are the main advantages over lead‑acid batteries?
A: Greater usable energy per charge, lighter weight, maintenance‑free operation, stable voltage under load, faster charging, and a much longer lifespan.
Q: What applications is this kit best suited for?
A: 48 V golf carts, UTVs/LSVs, utility and service vehicles, RV house banks, camper vans, mobile work platforms, food trucks, off‑grid battery systems, and other 48 V energy storage needs.
Q: Is installation straightforward?
A: Yes — designed for drop‑in replacement, the three EAGLE 2 modules are ready to connect into most 48 V systems with standard battery terminals.
Q: What safety features are included?
A: Integrated battery management systems (BMS) on each module provide protection against over‑voltage, under‑voltage, over‑current, and thermal extremes, and manage cell balancing for safe, reliable operation.
Q: What performance and reliability can users expect?
A: Stable power delivery under load, efficient recharge cycles, minimal self‑discharge, and many more charge/discharge cycles than comparable lead‑acid setups — translating to longer service life and consistent performance.
Q: Can this kit be expanded or paralleled?
A: Yes — depending on system design and inverter compatibility, additional battery modules or kits can often be paralleled to increase total energy storage and runtime.
Maintenance Tips
-
Install the EAGLE 2 Kit in a cool, dry, well-ventilated area to maintain stable 48V performance and extend LiFePO4 battery life.
-
Regularly inspect terminals, connectors, and wiring for looseness, corrosion, or damage to ensure safe and reliable operation.
-
Clean the battery casings with a soft, dry cloth to remove dust and prevent heat buildup.
-
Protect the kit from direct sunlight, moisture, and extreme temperatures to preserve cell health and efficiency.
-
Avoid deep discharges; monitor state of charge to maintain long-term capacity and performance.
-
For long-term storage, maintain batteries at 50–60% charge and disconnect from all loads.
