BigBattery FEAGL-48015-G1 48V Eagle Small Yet Remarkably Powerful Battery

Introduction

Introducing BigBattery’s EAGLE! The 48V EAGLE is a small, yet remarkably powerful battery, with a huge capacity for its size. Its sleek design is one indication of the care that is taken in the engineering and manufacturing of BigBattery batteries. Our design is intentional: to make a drop-in replacement of traditional lead-acid or lithium batteries a simple feat. The EAGLE battery features the safest lithium battery chemistry currently available, LiFePO4 (lithium iron phosphate), or LFP. By installing these batteries, you will reduce the overall weight of your vehicle, while adding a substantial amount of power. For example, just two (2) EAGLE units will increase power, and add range while subtracting weight when upgrading from a traditional 48V battery system (6 8-Volts, etc.). One (1) EAGLE unit can deliver 4,000 Watts of continuous power. It has 1.536 kWh of capacity, with a max discharge peak current of 180 Amps, for 6 seconds. BigBattery’s EAGLE batteries are guaranteed to last you at least 3,700 cycles, and realistically up to 5,500 or more full charge and discharge cycles. The EAGLE battery is an excellent solution for your golf cart needs. Our User Manual describes in detail the different viable installation methods, to get your golf cart outfitted right away with BigBattery state-of-the-art batteries. The mounting brackets provided give you several more options for mounting them in your battery bay. The brackets can add height, for example, to provide clearance over any dividers that may exist within your battery bay. Select from our EAGLE Kits (2-8 EAGLE units), to allow even more power, more range, and a less overall amperage draw from your battery system, increasing its cycle life even more. Please make special note of Section 7 towards the end of this Manual. You have the opportunity to share a tutorial of your BigBattery experience, which can help spread the word about our state-of-the-art batteries. Sharing your review may make you eligible for a special discount on future battery orders at BigBattery.com. We hope you enjoy reading and thank you for choosing BigBattery!

You can expect the EAGLE to last 3,700 – 5,500 full- charge/ discharge cycles to 100% Depth-of-Discharge (DoD), from the battery’s rated capacity. BigBattery is so confident in the quality and performance of our products that we provide you, with a 10-year non-prorated warranty.

The choice is clear. To fulfill your power needs, the EAGLE or other select BigBattery batteries will be the best answer, whether it’s for your golf cart, battery-powered equipment, small ESS, or a lithium-ion upgrade from any 48V application that was previously lead-acid. In choosing a battery solution from BigBattery, you have chosen a battery that provides the superior performance, reliability, and unparalleled value that our customers have come to expect. Equipped with the 48V EAGLE from BigBattery, you’ll stay powered and prepared!

Warnings & Precautions

Lithium Iron Phosphate (LiFePO4) is inherently safe chemistry. However, safety measures should always be taken. Adhere to the instructions within this User Manual for safe handling and operation.
Warnings:

• Do not charge with a charge voltage above 58.8V.
• Do not charge nor discharge the battery when the ambient temperature is above 55 °C (131 °F).
• Do not install a battery where it may contact conductive materials, water, seawater, strong oxidizers, or strong acids.
• Do not install the battery in a location exposed to direct sun, hot surfaces, or hot locations. Do not install batteries in a tight clearance compartment as overheating may result.
• Keep any flammable/combustible material (e.g. paper, cloth, plastic, etc.) that may be ignited by heat, sparks, flames, or any other heat source at a minimum distance of two feet away from the batteries.
• Disconnect batteries immediately if, during operation or charging, they emit an unusual smell, develop heat, or behave abnormally.
• Have a Class ABC or Class BC fire extinguisher on the premises.

Precautions:

• Handle batteries and/or battery-powered devices cautiously so as to not damage the battery casing or connections.
• Do not charge the battery if the ambient temperature is below 0 °C (32 °F), nor discharge the battery if the ambient temperature is below -30 °C (-22 °F).
• Before storing the battery for more than 6 months, charge the battery to 53V or above.
• For long-term storage, disconnect batteries from your power system.
• Always wear protective gear when handling batteries.
• Do not place any objects on top of batteries.
• Make sure all cable connections are properly tightened.
• Install and remove batteries using the handles provided.

Parts & Installation

WARNING: Before installing, make sure to review all warnings and precautions in Section 4, as well as the installation safety guidelines in Section 5.1 below.

Installation Safety Guidelines

• Inspect batteries upon receipt for any signs of damage before use.
• Check to ensure that all cables are in good condition.
• Use a screwdriver with a rubber-coated handle.
• When your battery has been charging and has come to maximum charge (up to 58.8V max.), your battery may experience a slight voltage drop either immediately or within an hour after unplugging. This is normal and should be no cause for concern.

Parts & Components

Battery Installation

Step 1:
Remove old batteries from your battery tray.

• Set your parking brake, turn the ignition key to the OFF position, and remove the key.
• If your cart has a Run/Tow switch, switch it to the Tow position.
• Disconnect all cabling, watering systems, and accessories from your old batteries and remove them.

Step 2:
Decide how you’ll install your busbar and set your EAGLEs into your battery tray.

• Things to consider:
• Proper weight distribution
• Proximity to where you’ll be installing your busbar
• Ability to easily connect or disconnect cables (cart to busbar and busbar to batteries)

Step 3:
Install your busbar using the hardware provided.

Step 4:
Connect cables to your busbar.

• Make sure you are always connecting your positive (+) terminals to the positive end of the busbar, and the negative (-) terminals to the negative end of the busbar.
• You should have one cable left over that is not plugged into an EAGLE unit. This will be for charging.

Step 5:
Set your EAGLEs in your battery tray and secure them with the mounting hardware provided.

• Mounting brackets are height-adjustable and can be installed on any side of your EAGLEs so you can clear any dividers in your battery tray.

Step 6:
Plug-in cables connected to your busbar to your EAGLE batteries.

• Ensure cables have a secure connection by pushing them in all the way

Step 7:
Connect Charge Display to your EAGLEs.

• Identify which EAGLE(s) has the Charge Display pigtail coming out of the back of the unit.
• Connect your Display extension cable to that EAGLE.
• Connect the Display extension cable to your Charge Display

Step 8:
Install your Charge Display in the cabin area or on the dashboard of your golf cart.

• 3 options for installation:

1. Remove adhesive covering from the back of the unit and stick the entire unit onto the cart. Secure cable to cart.
2. Remove the back cover of the unit. Disconnect the Display extension cable. Make a cutout on your cart and secure the front of the unit in the cutout. Feed extension cable through the cart and reconnect unit.
3. Unplug and remove the black LED display from the unit. Make a cutout on your cart and secure an LED display to your cart. Feed the cable through your cart and reconnect the cable to the LED display

Charging & Troubleshooting

Charging Option 1

• Connect the spare 175A connector in your battery tray to the 175A connector on your charger.
• Connect the AC plug on your charger to an outlet or other 110V power source and begin charging.

Charging Option 2

• Remove your spare 175A connector cable from your busbar.
• Connect your cart’s onboard charging terminals to your busbar.
• Connect the charging adapter for your cart to the 175A connector on your charger.
• Connect the AC plug on your charger to an outlet or other 110V power source and begin charging.

Troubleshooting
If the breaker trips or the battery turns off:

• Unplug all EAGLEs
  • If an EAGLE unit remains on after you have unplugged it, this means that the unit was properly synced and connected and no further action needs to be taken.
  • If an EAGLE unit shuts off after unplugging, then you will have to turn it back on by cycling the breaker or pressing the BMS Reset button found on the back of the unit.

Recycling

Please dispose of LiFePO4 batteries at an authorized lithium recycling facility, or return to BigBattery. We can take care of recycling your batteries for you.
