User Manual for EcoFlow 12V 100Ah Deep Cycle Marine Trolling Motor Battery

Quick guide from the manual

Before using your EcoFlow 12V 100Ah Deep Cycle Marine Trolling Motor Battery, please note the following essential information:

• Initial Charge: The battery is shipped at 50% state of charge. Please charge it fully before first use.
• Orientation: Upright battery placement is recommended. Do not install the battery in an inverted state (terminals facing down).
• Environment: Install in a tidy, dry, and well-ventilated environment. Keep away from moisture, flammable materials, and extreme temperatures.
• Maintenance: Perform maintenance checks every 6 months, including inspecting power cables, screws, and bus bars.
• Emergency: In case of fire, use water, sand, fire blanket, dry powder, or carbon dioxide fire extinguishers in that order.

Product Overview

The EcoFlow 12V Lithium Battery utilizes lithium iron phosphate technology and features a built-in high-precision Battery Management System (BMS) to monitor voltage, current, and temperature. It includes a passive balance feature to optimize performance. This battery is designed for use in RVs, marine systems, solar lights, golf carts, trolling motors, and small energy storage applications.

Installation

Ensure the installation environment is dry and stable. If installing in an enclosed space, ensure adequate ventilation and airflow.

Installation Procedure

1. Fix the battery: Use a battery tray adapted to Group 27 batteries to secure the unit.
2. Prepare terminals: Remove dust covers from the terminals.
3. Cable preparation: Run connection cables through the provided insulating sleeves.
4. Install terminals: Connect the cables to the battery terminals. Do not place washers between the terminal bolt and the cable lug, as this can cause high resistance and excessive heating. Tighten to 109.7 lbf·in (12.4 N·m).
5. Insulate: Install the insulating sleeves over the connections.
6. Connect devices: Connect the battery to your system (shunt, inverter, MPPT controller, etc.).
7. Secure: Buckle the lifting strap through the strap holes and fasten tightly.

Connecting Batteries in Series or Parallel

Before connecting multiple batteries, you must balance them to reduce voltage differences:

• Use a qualified battery balancer.
• Ensure the voltage difference between batteries is less than 0.1V.
• Connect all batteries in parallel and let them rest for 12 to 24 hours.

You can connect batteries directly or use busbars for efficient power distribution. The system supports various configurations, including series (up to 4 batteries) and parallel (up to 8 batteries) connections.

Maintenance

Regular maintenance is required to ensure longevity:

• Power Cables: Check for mechanical damage and ensure secure installation every 6 months. Tighten loose screws with a torque wrench.
• Cleanliness: Clean the battery surface with a dry cloth every 6-12 months if dust is present.
• System Check: Verify all parameters (voltage, current, temperature) and check air ducts for blockages every 6 months.
• Charge/Discharge Maintenance: Perform shallow charging and discharging using low-power loads every 6 months.

Troubleshooting

If you encounter issues, refer to these common solutions:

• Interruptions during high power use: Likely Overtemperature Protection. Disconnect input/output and allow the battery to cool down.
• No DC output: Battery voltage is low. Charge the battery.
• Power supply time too short: Potential battery cell failure. Replace the battery.
• Battery won't charge fully: DC output voltage in the system is too low. Adjust the system voltage.
• Insufficient capacity: Cell voltage imbalance. Check or balance the cells.
