BigBattery 48 V 2× EAGLE 2 Kit — Twice the Power, One Smart Solution
Upgrade your 48-volt system with a ready-to-install bundle featuring two high-performance LiFePO₄ modules plus charger and monitoring tools. Ideal for golf carts, utility vehicles, RVs, and other 48V platforms where longer runtime and reliability matter.
Why Choose the 2× EAGLE 2 Kit
-
Double the capacity in one package — This kit combines two 1.63 kWh (32 Ah) EAGLE 2 modules to deliver 3.26 kWh of usable energy, helping you go farther between recharges.
-
Drop-in replacement for lead-acid — The modules use a compact GC2 form factor, designed to mirror many T-105 lead-acid battery trays. Straightforward install with minimal changes.
-
Advanced chemistry + durability — Uses Tier-1 LiFePO₄ cells, known for longer life, greater thermal stability and better cycle performance than traditional lead-acid packs.
-
Built for real environments — IP67-rated enclosure protects against dust and water. Self-heating and wide temperature operational range let the pack perform in cold or hot conditions.
-
Smart monitoring & connectivity — Includes external State-of-Charge (SOC) meter and supports CANbus communications for deeper integration and monitoring.
-
Expandable & scalable — Supports parallel expansion (up to ten modules) if you later need even greater energy capacity.
Ideal Use Cases & Value Propositions
-
Golf carts & utility vehicles — Far longer runtime than older lead-acid packs, with less maintenance and weight.
-
48 V UTVs, LSVs, RVs/Camper vans — Provide reliable power for larger loads, accessories, or extended off-grid use.
-
Industrial & fleet equipment — One kit giving high energy density, robustness and scalability without large footprint.
-
Cold-weather/unreliable conditions — Self-heating, durable housing and advanced BMS mean better performance even in harsh conditions.
-
Future-ready systems — Start with this kit, then expand by paralleling more modules if your energy needs grow.
