BigBattery LiFePO4 Battery | 36V 40Ah 1.54kWh | EAGLE 2 | Heater & Comms

Compact Drop-In LiFePO₄ Upgrade for 36V Systems with Built-In Heater and CANbus Monitoring

The BigBattery FEAGL-36015-G2 EAGLE 2 is a high-performance 36V LiFePO₄ battery designed to modernize legacy 36V platforms with a direct-fit GC2/T-105 tray form factor. Ideal for golf carts, NEVs, industrial equipment, marine applications, and other 36V systems, this battery delivers higher power, longer life, and superior reliability compared to traditional lead-acid packs. With integrated heating and CANbus communications, it provides cold-weather readiness and intelligent system integration.

Key Features:

  • Direct Drop-In Replacement for 36V Lead-Acid Packs: Fits most GC2/T-105 tray mounts and upgrades existing systems without major controller changes.
  • Premium LiFePO₄ Chemistry: Tier-1 cells provide longer cycle life, better thermal stability, and enhanced safety.
  • Integrated Heater & Communications: Built-in self-heating ensures reliable performance in cold climates, while CANbus enables smart monitoring and integration.
  • High-Power Output: 80A continuous discharge (~3,072W) with 200A peak for short bursts.
  • Durable, Weather-Resistant Design: IP67 / NEMA-6 rated housing protects against dust and immersion for rugged use.
  • Expandable System Design: Supports up to 10 units in parallel for larger capacity banks.

Ideal Applications:

  • Golf carts and NEVs using 36V lead-acid packs
  • Industrial equipment and forklifts with 36V systems
  • Marine and RV 36V house power setups
  • Light electric vehicles and custom mobility platforms

What’s Included:

Understanding Your Power Needs

Power Calculation Guide

Sizing Metric Formula & Example
Energy Consumption (Wh) Formula: Watts × Hours
Example: 60W × 4 hrs = 240 Wh
Battery Capacity (Ah) Formula: Watt-hours ÷ System Voltage (V)
Example: 240 Wh ÷ 12V = 20 Ah
Inverter Size (W) Formula: Total Watts × 1.25 (safety margin)
Example: 300W × 1.25 = 375W → Use 400W inverter
Total Load Power (W) Formula: Sum of all appliance watts used simultaneously
Example: Light (10W) + Fan (75W) = 85W
Runtime (hrs) of Battery Formula: (Battery Ah × Voltage) ÷ Total Load (W)
Example: (100Ah × 12V) ÷ 240W = 5 hrs
