The BigBattery 36V EAGLE 2 Converts 36V Golf Carts and Equipment to Lithium With a Self-Heating, CANBus GC2 Battery
The BigBattery 36V EAGLE 2 is a 38.4V, 40Ah lithium iron phosphate battery that stores 1.54kWh in the standard GC2 case size, the same footprint as a Trojan T-105. It is built for 36V golf carts and neighborhood electric vehicles, tuggers, pallet jacks, floor sweepers and other industrial equipment, as well as marine and RV house systems.
Each EAGLE 2 has Tier 1 LiFePO4 cells, an advanced battery management system, built-in self-heating, CANBus communication and an IP67 / NEMA 6 waterproof, dustproof case. At 38 lbs, it weighs far less than the lead-acid battery it replaces. BigBattery backs the EAGLE 2 with a 12-year warranty and lifetime USA-based technical support.
BigBattery 36V EAGLE 2 LiFePO4 Battery Features
GC2 Drop-In Replacement
The EAGLE 2 is built in the GC2 form factor, so it fits standard battery trays and hold-downs for Trojan T-105 and similar batteries with little or no modification.
Consistent Power With No Voltage Sag
It delivers 80A (3,072W) continuously with a peak of 200A for 3 seconds, and holds its voltage under load, so equipment runs at full speed until the battery is nearly empty.
5,000+ Cycle Life
BigBattery rates the 36V EAGLE 2 for more than 5,000 cycles, many times the life of a lead-acid golf cart battery.
IP67 Waterproof and Dustproof
The IP67 / NEMA 6 rating means the case is dust-tight and protected against temporary immersion, which suits sand, splash and washdown.
Built-In Self-Heating
An integrated heater manages charging in cold weather, so the battery can charge from -4°F to 131°F.
CANBus Communication
The battery reports state of charge and system data over CANBus to compatible equipment, chargers and meters, such as the BigBattery EAGLE 2 COMM SOC meter.
Fast Charging, Zero Maintenance
It accepts up to 40A of charge current and needs no watering, equalizing or terminal cleaning.
Real-World Applications
36V golf carts. Swap the lead-acid batteries in Club Car, EZGO, Yamaha and similar carts that use GC2 batteries.
NEVs. Get longer runtime and faster charging for neighborhood electric vehicles.
Tuggers, pallet jacks and floor sweepers. Run light industrial equipment without watering or acid.
Marine and RV. Power house loads with a waterproof lithium battery.
How It Compares to Common Alternatives
Versus flooded lead-acid GC2 batteries. Lead-acid batteries need watering, sag under load and wear out quickly when deeply discharged. EAGLE 2 is maintenance-free, holds its voltage and lasts thousands of cycles.
Versus larger single-pack conversions. A single large lithium pack may need a new tray or bracket. EAGLE 2 uses the existing GC2 trays, so conversions stay simple.
Is This EAGLE 2 Battery the Right Fit
-
System voltage. 36V systems, or higher-voltage systems built from several EAGLE 2 batteries as your equipment requires.
-
Battery tray. GC2 / Trojan T-105 size trays, 7.1 x 10.2 x 10.8 in.
-
Charger. A lithium charger matched to the 36V EAGLE 2 charge voltages in the specification table.
-
Parallel. Up to 10 EAGLE 2 batteries in parallel.
This may be a good fit if
- You are replacing Trojan T-105 or other GC2 lead-acid batteries
- Your equipment sees water, sand or washdown
- You want maintenance-free batteries that charge in the cold
- Your equipment can use CANBus battery data
Common Questions
Can It Replace Trojan T-105 Batteries?
Yes. The EAGLE 2 is built in the GC2 form factor, the same size as a T-105, so it drops into standard battery trays with minimal or no modification.
How Many 36V EAGLE 2 Batteries Do I Need?
Base it on your motor and controller. BigBattery suggests two (3.08kWh) for small carts and short-range NEVs, three (4.62kWh) for extended-range carts and industrial equipment, and four (6.16kWh) for heavy-duty carts and long runtime.
Will It Fit My Club Car?
If your cart uses GC2 batteries such as the T-105, yes. It drops into standard Club Car, EZGO and Yamaha trays.
Is It Waterproof?
Yes. It is rated IP67 / NEMA 6, dust-tight and protected against temporary immersion.
Will It Charge in Cold Weather?
Yes. The built-in heater allows charging from -4°F to 131°F.
