    Reliable Charging in Australia’s Coldest Conditions

    Designed to perform even in Australia’s cooler climates, the self-heating function ensures efficient charging when temperatures drop. When charging in cooler conditions, the power supply first activates the internal battery heating pad, warming the battery until it reaches 10°C (50°F), at which point heating automatically stops, and charging begins. The BMS-controlled self-heating function operates when charging between -20°C to 5°C (-4°F to 41°F), ensuring reliable charging and stable power backup in cold conditions. It efficiently brings the battery to the optimal temperature within 40-70 minutes from -10°C (14°F) and 80-120 minutes from -20°C (-4°F), providing consistent performance even in low-temperature environments.

    FAQ

    Q: Can this Dual Purpose Lithium Starting Battery be used to start a car engine?

    A:

    No, this battery should not be used as a starter battery for cars, motorcycles, tractors, or any other vehicles. It is specifically designed for marine applications, including fuel-powered outboard motors.

    To ensure the best use of your battery, keep the following in mind:

    • Starting Applications: This battery is not suitable for automotive cranking applications.
    • Engine Compatibility: Not compatible with older outboard motors without an internal voltage regulator. If you need assistance, please contact us.
    • Mounting Considerations: If used in marine settings (such as fuel outboard motors) or high-vibration environments, the battery must be securely mounted.
    • Secure Installation: To prevent movement and potential damage, always ensure the battery is tightly fastened when used in outboard motor applications or unstable conditions.
    • Cable Length Management: Position the battery as close as possible to the outboard motor to reduce voltage drop, which can range between 3%-10%. If the voltage drop is excessive, shorten the cable length.
    • Water Protection: The battery has an IP67 rating, meaning it is water and dust-resistant but should not be fully submerged. To avoid water exposure, place the battery in a waterproof battery container or mount it in an elevated, dry location.

    Q: What’s the Difference Between a Cranking Battery, Deep Cycle Battery, and Dual-Purpose Battery?

    A:

    Cranking Battery – Designed for engine ignition, providing high Cold Cranking Amps (CCA) for a quick, powerful burst of energy to start fuel-powered motors. Not ideal for sustained power supply.

    Deep Cycle Battery – Built for long-term power supply, capable of deep discharge cycles but lacks the high cranking power needed to start an engine.

    Dual-Purpose Battery – A versatile option that combines both starting and deep cycle functions, making it suitable for boats requiring both engine ignition and power for onboard electronics.

    Q: What are Cold Cranking Amps (CCA) and Marine Cranking Amps (MCA), and Why Are They Important for Marine Starting Batteries?

    A:

    CCA (Cold Cranking Amps) and MCA (Marine Cranking Amps) are key indicators of a battery’s starting power.

    CCA (Cold Cranking Amps): Measures the current (in amps) a battery can provide for 30 seconds at -18°C (0°F) while maintaining a voltage of at least 7.2V. It is mainly used for vehicles operating in cold environments.

    MCA (Marine Cranking Amps): Similar to CCA, but measured at 0°C (32°F) instead. The test conditions are the same—sustaining the current for 30 seconds while keeping the voltage above 7.2V. MCA is specifically used for marine applications.

    The only difference between CCA and MCA is the testing temperature. Both ratings help determine a battery’s ability to start an engine under different weather conditions.

    How Does LiTime Define These Ratings?

    LiTime's 12V 140Ah dual-purpose battery is tested at different temperatures and provides four cranking current values:

    CCA (-18°C)

    CCA (-10°C)

    MCA (0°C)

    HCA (25°C)

    These values indicate the battery’s cranking performance at various ambient temperatures. LiTime defines these ratings based on the highest current the battery can sustain for 1 second at each temperature without triggering its built-in protection system.

    Why Is the Cranking Test Based on 1 Second?

    Through extensive research on engine starting requirements, we found that in real-world applications, an engine typically requires a cranking current for only milliseconds. By testing at 1-second duration, we ensure the battery has ample power reserves, guaranteeing reliable engine starts.

    Q: Can I connect the battery in series or parallel?

    A:

    Yes, but there are limitations based on the intended use:

    1. For Starting & Deep Cycle Applications:

        a. Supports up to 4 identical batteries connected in parallel.

        b. Maximum configuration: 12V (12.8V) 560Ah battery system.

        c. ⚠️ Only parallel connections are supported; series connections are not allowed.

    2. For Energy Storage Applications:

        a. Supports up to 16 identical batteriesin the following configurations:

            i. 4 in series for a 48V (51.2V) system

            ii. 4 in parallel for a 560Ah system

    Before connecting batteries, ensure the following:

    They must be identical models with the same capacity (Ah) and BMS specifications (A).

    All batteries should be from the same brand to ensure BMS compatibility.

    Batteries should be purchased within the same period (within one month) for consistent performance.

    Q: What should I do when I receive the battery?

    A:

    Since batteries may arrive with a low State of Charge (SOC) due to shipping and storage, follow these steps:

    1. Charge the battery immediately to prevent over-discharge and ensure optimal performance.

    2. Use a LiFePO4 battery charger to fully charge the battery before first use.

    3. Ensure the battery voltage is above 11.5V before attempting to start a motor.

    4. Monitor via Bluetooth: The built-in Bluetooth function allows you to track the battery’s voltage and capacity when under load for an extended period. Ensure the voltage does not drop below 11.5V.

    5. Starting Guidelines:Do not crank the motor for more than 3 seconds per attempt.

        a. If the first attempt fails, wait 15 seconds before trying again.

        b. If the motor fails after 3 attempts, inspect the system and wait 5 minutes before trying again.

    🔹 For Bluetooth models:

    Some batteries may arrive in anoff state, showing a virtual voltage of 3V-5V. This is normal. To activate:

    Use an AC-DC LiFePO4 charger or MPPT solar charge controller to charge for 3-10 seconds. This will wake the battery for normal operation.

    🔹 For long-term storage:

    Charge the battery to 50% SOC before storage.

    Perform a maintenance charge every 3 months to preserve battery life.

    Q: How do I charge the battery?

    A:

    There are four recommended charging methods:

    1. Solar Panel & Controller

    Recommended Solar Power: 600W or higher

        ○ A 600W solar panel can fully charge the battery in a single day under optimal sunlight conditions (approx. 4.5 hours of effective sunlight).

        ○ Charging may take longer in areas with less sunlight.

    Recommended Charging Current:

        ○ 28A (0.2C) → Fully charges in ~5 hours

        ○ 70A (0.5C) → Fully charges in ~2 hours

    Charging Mode: Set to 12V (14.6V) LI (LiFePO4) mode.

    2. Battery Charger

    Use a marine battery charger to optimize charging efficiency.

    Recommended Charging Voltage: 14.2V - 14.6V

    Recommended Charging Current:

        ○ 28A (0.2C) → Fully charges in ~5 hours

        ○ 70A (0.5C) → Fully charges in ~2 hours

    Best Practice: Disconnect the charger once charging is complete to prevent overcharging.

    3. Alternator (Using an DC-DC Charger)

    Requires a DC-DC charger to regulate voltage and prevent overcharging.

    Charging Voltage: 14.2V - 14.6V

    Charging Current:

        ○ 28A (0.2C) → Full charge in ~5 hours

        ○ 70A (0.5C) → Full charge in ~2 hours

    4. Generator (Using a AC-DC Charger)

    Use an AC-DC LiFePO4 charger for safe and efficient charging.

    Charging Voltage: 14.2V - 14.6V

    Charging Current:

        ○ 28A (0.2C) → Full charge in ~5 hours

        ○ 70A (0.5C) → Full charge in ~2 hours

    By following four guidelines, Australian users can maximise the performance, safety, and lifespan of their LiTime 12V 140Ah Dual-Purpose Marine Battery. 🚤🔋

    Q: Do I still need a separate Bluetooth battery monitor to track my battery's status?

    A:

    No, you don’t need an additional Bluetooth battery monitor. The LiTime 12V 140Ah Dual-Purpose Marine Battery comes with a built-in Bluetooth 5.0 monitoring system, allowing you to check the real-time status of your battery directly from your smartphone via the LiTime app.
