Frequently Asked Questions
What comes in the 36V Eagle 2 kit?
The 2x configuration includes two 36V Eagle 2 batteries with heater and CANBus for 3.08kWh total, an Eagle 2 COMM SOC meter, 4AWG red and black ring-to-ring cables, and a 36V 25A charger with ring terminals. Everything needed for the conversion is in the box.
Is a 2x kit enough for my golf cart?
For a standard cart on flat terrain doing short to moderate runs, 3.08kWh is a solid fit. If you carry passengers, run hills, or need all-day range, step up to the 3x or 4x configuration. Match the choice to your motor and controller specs, not just to capacity.
How far will a 3kWh 36V golf cart go?
Range depends on terrain, load and driving style, but a typical 36V cart draws roughly 100 to 150Wh per mile on flat ground. That puts 3.08kWh in the region of 20 to 30 miles. Hills, heavy loads and frequent stops reduce it.
Does the 36V kit include a charger?
Yes. A 36V 25A charger with ring terminals is included, delivering 43.2V DC from a standard 110V AC outlet. That matters because a lead-acid charger uses the wrong profile for LiFePO4 and will leave the pack undercharged.
Will this kit fit a Club Car or EZGO?
If the cart uses GC2 batteries, yes. Each Eagle 2 is a GC2 drop-in compatible with Trojan T-105 trays, so it fits standard 36V cart battery compartments with minimal or no modification.
What does the 4x 36V Eagle 2 kit give me?
Four Eagle 2 batteries for 6.16kWh total, roughly double the 2x configuration. It is built for high-demand use: heavy-duty carts, long runtime requirements, larger off-grid setups and utility vehicles that run continuously rather than in short trips.
2x, 3x or 4x: which 36V Eagle 2 kit should I choose?
2x at 3.08kWh handles light duty, small carts and short-range NEVs. 3x at 4.62kWh covers extended range carts, industrial equipment and RV systems. 4x at 6.16kWh is for heavy-duty carts, long runtime and larger utility or off-grid systems.
How many batteries do I need for a heavy-duty cart?
Heavy-duty carts carrying passengers, towing, or working hilly terrain generally need the 4x configuration. Confirm your motor and controller can handle the bank, since matching the configuration to the vehicle's specification matters more than raw capacity.
What is the longest range 36V lithium kit?
The 4x configuration at 6.16kWh gives the most runtime in this range. At roughly 100 to 150Wh per mile on flat ground, that puts you in the region of 40 to 60 miles depending on terrain, load and driving style.
Does the 4x kit include everything needed?
Yes. It ships with four 36V Eagle 2 batteries, an Eagle 2 COMM SOC meter, three sets of 4AWG red and black ring-to-ring cables, and a 36V 25A charger. Each battery includes a built-in heater and CANBus communication.
