3. Setup

3.1 Initial Charging

Before first use, it is recommended to fully charge the battery. The ECO-WORTHY 12V 30Ah LiFePO4 battery can be recharged using a compatible 12V 10A battery charger or a 100W solar panel.

Figure 3.1: Illustration of charging methods. A 12V 10A battery charger can fully charge the battery in approximately 3 hours, while a 100W solar panel can charge it within one sunny day.

3.2 Connecting Multiple Batteries (Capacity Expansion)

The ECO-WORTHY 12V 30Ah LiFePO4 battery supports both parallel and series connections to expand capacity or increase voltage.

• Parallel Connection: Connect batteries in parallel to increase total Amp-hour (Ah) capacity while maintaining 12V. There is no limit to the number of batteries that can be connected in parallel. Ensure all batteries are of the same type and voltage.
• Series Connection: Connect up to 4 identical batteries in series to increase the voltage (e.g., 24V, 36V, 48V). For example, four 12V batteries in series will create a 48V battery bank.

Figure 3.2: Visual guide for connecting batteries in parallel (left) to increase current capacity at 12V, and in series (right) to increase voltage up to 48V (using four batteries).

Important: Always ensure batteries are of the same type and charge level before connecting them in series or parallel. Consult a qualified electrician if unsure about wiring configurations.

4. Operating Instructions

4.1 General Usage

Figure 4.2: Visual warning against using the battery for starting diesel generators or motorcycles, as it is not designed for high cranking amps.

• Ensure proper ventilation when charging or discharging.
• Avoid short-circuiting the battery terminals.
• Do not expose the battery to extreme temperatures or direct sunlight for prolonged periods.
• Keep out of reach of children.

5. Maintenance

Proper maintenance ensures the longevity and optimal performance of your LiFePO4 battery.

• Regular Charging: While LiFePO4 batteries have a low self-discharge rate (approximately 3% per month), it is advisable to charge them regularly, especially if stored for extended periods.
• Temperature Control: Operate and store the battery within the recommended temperature ranges (Charging: 32-131°F / 0-55°C; Discharging: -4-131°F / -20-55°C).
• Terminal Inspection: Periodically check battery terminals for corrosion or loose connections. Clean as necessary.
• BMS Protection: The built-in BMS actively manages the battery to prevent damage from overcharge, over-discharge, and other issues, minimizing the need for manual intervention.
