Read Before Install & Use & Care

Important Safety and Usage Guidelines:

• ?️ Heavy Team Lift Required
• ⚡ High Voltage - Handle With Care
• ?? Do Not Pressure Wash or Submerge
• ? Charge Battery Before Use

Warnings

• High Voltage. DO NOT install or service this battery unless you are properly trained.
• Use only with components that have the same voltage and current rating as the battery.
• DO NOT touch or connect to the terminals unless the battery is manually turned off.
• DO NOT open or attempt to service the battery; there are no user-serviceable parts inside.

Use & Care

• Charge the battery daily to ensure it is always fully charged and ready to use.
• Batteries will not charge if the internal battery temperature falls below 34°F (1°C).
• DO NOT pressure wash, submerge, or use chemical agents to clean your battery.
• Clean the battery using a damp cloth that does not include chemical agents.

Battery Components

The Eco Battery Gen2 Lithium Battery features the following components:

• Lifting Handles: For safe and secure transport.
• Positive Terminal: Connection point for positive power.
• Power Button: Controls power flow and acts as a safety device.
• CAN Connectors: Communication ports for diagnostics, chargers, or motor controllers.
• Negative Terminal: Connection point for negative power.
• COM Port: Communication port.
• METER / CAN CABLE: Connects the State of Charge Meter and CAN ports.
• STATE OF CHARGE METER: Displays battery status.

State of Charge (SOC) Meter

The SOC meter provides real-time battery status:

• Battery Voltage: Varies based on current load or charge.
• State of Charge: Displayed in percentage (0% = empty, 100% = full).
• Battery Current: Negative for discharge, positive for charging.

Meter Calibration: The meter self-calibrates; no user calibration is required. Accuracy is +/- 5%. Monitor SOC % for accurate state of charge, rather than voltage.

Usage Advice: Avoid running the battery below 20% State of Charge. Monitor your battery's SOC like a vehicle's fuel gauge.

Meter Sleep Timer: The meter may enter a sleep mode after inactivity. It wakes up when current flows in or out of the battery.

Diagnostic Trouble Codes (DTCs): If a battery fault is detected, the meter may display DTCs. If a trouble code appears, record it and contact your dealer for assistance. Example: E08-3 DchgOverCur indicates a discharge overcurrent fault.

Power Button Operation

The power button controls the flow of power and serves as a safety device for handling and storage. It must be turned ON to charge or discharge the battery.

• To Power On: Press and release the power button until the green light illuminates.
• To Power Off: Press and release the power button until the green light turns off.

The battery will automatically power off to conserve power if not charged or driven for an extended period. For use within 15 days, it is recommended to leave the power button ON and the charger connected. If the cart will be unused for longer than 15 days, fully charge the battery, disconnect the charger, and turn the battery OFF.

CAN Connectors

The two CAN connectors on the meter cable are used for diagnostics or communication with a charger or motor controller. If your charger or motor controller is CAN enabled and compatible with the Eco Battery CAN protocol, connect the appropriate CAN connector.

Charger and Charging

Use only genuine Eco Battery lithium chargers or chargers specifically approved by Eco Battery to ensure optimal charging and extend battery life. DO NOT use unapproved chargers or tenders. DO NOT connect DC output cables with reverse polarity, as this will cause irreversible damage and void the warranty.

Charging Instructions:

1. Connect the DC output ring terminals to the battery terminals.
2. Connect AC input to AC power.
3. The charger LED will blink red when charging and turn solid green when complete.

Note: The battery must be powered ON with the power button illuminated to accept a charge. If your charger utilizes CAN charging, connect the CAN connector from the charger to one of the CAN ports on the meter cable.

Charge Time:

Charge time can be calculated using the formula: Ah Capacity of Battery / Charging Amps of Charger. For example, a 105Ah battery with a 15A charger will take approximately 7 hours to charge from fully depleted.

Recommended Extension Cord Lengths:

• Up to 15': 12-14 AWG
• 10 to 25': 10-12 AWG
• Exceeding 25': Not recommended

Eco Battery chargers are not float chargers or maintainers. If left plugged in, the battery may drop to around 90% SOC before initiating a new charge cycle. Charging every night is acceptable and ensures the battery is always ready.

All Eco Battery chargers support AC input of 100-250 VAC, single phase, 50 or 60 Hz.

Power Save Mode

Batteries built after 08/01/2022 (or with updated firmware) may enter Power Save Mode after extended inactivity to prevent full depletion. When active, the battery, meter, and power button turn off. To exit Power Save Mode, cycle the power button. The green LED on the power button will not be illuminated in this mode. To wake the battery, turn the power button off and then back on. If the battery has entered sleep mode, fully charge it before use.

Storage

For long-term storage, fully charge the battery, unplug the AC power source, and turn off the power button. After storage, fully charge the battery before use, as the SOC may drift. It is recommended to charge the battery every 6 months.

Cold Storage: If storing a golf cart below -20°F (-29°C), remove the battery and store it in ambient temperatures above -20°F (-29°C). The battery functions between -20°F (-29°C) and 32°F (0°C) but will not accept a charge below 32°F (0°C).

Warranty Warning: Using third-party battery chargers or tenders will void the battery's warranty.

Cleaning

Be mindful of sensitive electronics when cleaning. DO NOT PRESSURE WASH the battery, as this can damage the lid seal and is not covered by warranty. Recommended cleaning methods include using a leaf blower or wiping with a clean damp cloth. NEVER USE CHEMICALS.

Cold Weather Operation

The battery is equipped with a temperature sensor that will shut it down below -20°F (-29°C) core temperature to prevent cell damage. The battery will discharge down to -20°F (-29°C) but will not accept any charge below 32°F (0°C), including plug-in or regenerative charging.

Driving golf carts with regenerative systems in temperatures below 32°F (0°C) is not recommended, as it may trigger self-protection mode or braking system faults.

Performance may decrease in colder temperatures, resulting in shorter run times, slower acceleration, and larger voltage drops.

Gen 2 BMS Error Codes

The Battery Management System (BMS) may generate error codes:

Error Level Definitions:

• Level 1: Serious Fault. Will not self-resolve. Contact Eco Battery.
• Level 2: Major Fault. Will self-resolve if conditions allow.
• Level 3: Minor Fault. Will self-resolve if conditions allow.
