2. Safety Guidelines

• Always wear proper personal protective equipment (PPE) including eye protection and gloves when working on batteries.
• Do not disassemble the cells. Disassembly may generate an internal short circuit, causing gassing, firing, or explosion.
• Do not soak the battery in water, seawater, or non-alcoholic drinks.
• Never attempt to charge a battery when the temperature is below 32°F (0°C) or above 113°F (45°C).
• Never store batteries below 30% state of charge.
• Do not use this battery for engine starting or golf cart applications.

3. Product Features

• Group 24 Size: Designed to meet BCI Group 24 standard dimensions (10.23×6.61×8.30 inches) for direct replacement of traditional G24 lead-acid batteries.
• Superior Lifespan: Up to 15,000+ cycles at 60% Depth of Discharge (DOD), 8,000+ cycles at 80% DOD, and 4,000+ cycles at 100% DOD.
• Built-in 100A BMS: Ensures safe and stable operation with protection against overcharge, over-discharge, overcurrent, and short circuit.
• Expandable Design: Supports up to 4 units in series or 4 in parallel for a maximum capacity of 400Ah and voltage up to 51.2V.
• Lightweight & Portable: Weighs approximately one-third of a standard lead-acid battery, featuring an upgraded portable strap handle for easy carrying.

4. Installation

The LIPULS 12.8V 100Ah-G24 battery is designed for easy installation as a direct replacement for Group 24, 27, or 31 lead-acid batteries. Ensure proper terminal connections and secure mounting.

• Battery Orientation: The battery is upright as the bottom of the case is flat. It can be placed on its short sides or long side, but always with the positive side up.
• Terminal Connection: Use the provided M8 terminals (12mm and 16mm lengths) to securely connect your cables. Tightly screw in the post bolts to prevent heat buildup.
• Placement: Ensure at least 4 inches of space around all sides and the top of the battery for proper ventilation. The battery case is non-combustible.

5. Charging

The material characteristics of LiFePO4 batteries differ from lead-acid batteries. Therefore, it is recommended to select a specific LiFePO4 charger for your charging mode.

• Recommended Charging Voltage: Between 13.8V to 14.6V.
• Recommended Charging Current: 20A (0.2C). The battery will be fully charged in approximately 5 hours to 100% capacity.
• Solar Charging: For solar panel systems, a power output of >550W is recommended for full charge within one day (with effective sunshine 5 hours/day).
• Alternator/Generator Charging: If using an alternator or generator, a DC-to-DC charger is needed to be added between the battery and the generator to ensure proper charging.

7. Storage & Maintenance

• Long-Term Storage: A fully charged LIPULS 12V battery can be safely stored in climate-controlled conditions for up to one year. It is recommended to check the battery state of charge every 4-6 months.
• Temperature: The battery can be operated at a temperature of -4°F to 95°F (-20°C to 35°C). Store in a fireproof container and away from children.
• Capacity: For prolonged storage, it is best to store your battery at a 50% charge level and recharge every 3 months if it is not being used for a long time.
• Avoid Prolonged Discharge: Never put the battery into prolonged storage below 30% state of charge.

8. Troubleshooting

If the battery stops working, it may be due to the BMS shutting off for protection. Follow these general steps to reactivate it:

1. Cut off all connections from the battery.
2. Leave the battery aside for 30 minutes. The battery will automatically recover itself to a normal voltage (>10V) and can then be fully charged.
3. If the battery is unable to recover itself after the above steps, try activating it by using a charger with a 0V charging function to fully charge the battery.
