        FAQ

        Q: How do I monitor the battery status?

        A:

        The battery includes an embedded Bluetooth module, which allows you to monitor the battery status using your smartphone and the Power Queen App.

        Q: Can I charge Power Queen 36V 50Ah Smart Deep Cycle Lithium Batteries in cold temps (below freezing)?

        A:

        The Power Queen 36V 50Ah Smart Deep Cycle Lithium Batteries can charge from 0℃ to 50 ℃ (32℉ to 122 ℉). The 36V 50Ah TM version incorporates a low-temperature charging protection mode that stops charging when it drops below 0℃.   It is advised that the battery be charged indoors on cold days.

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

        A:

        The Power Queen 36V 50Ah lithium battery allows you to connect up to four identical batteries in parallel for a 36V(38.4V)200Ah battery system. However, the battery does not permit connecting in series.

        To connect in series or parallel, batteries must meet the following conditions:

        • Identical batteries with the same capacity (Ah) and BMS (A);
        • From the same brand (since lithium batteries from different brands have their own BMS);
        • Purchased within a month.

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

        A:

        Please be aware that your battery may have a low State of Charge (SOC) after shipping and storage. To avoid overdischarge, we recommend charging the battery promptly.

        Bluetooth batteries may come in an off condition, with a virtual voltage of 3 to 5V at the terminals. This is typical and may be remedied by charging the battery for 3 to 10 seconds with an AC-DC LiFePO4 lithium battery charger or an MPPT solar charge controller, allowing it to function normally.

        If you plan on storing the battery for a lengthy period of time, charge it to a state of charge (SOC) of 30% to 50% and perform maintenance every three months. This method will help it retain its functionality and performance over time.

        Q: What is the ideal thrust range for a Power Queen 36V 50Ah trolling motor battery?

        A:

        The ideal thrust range is 100-120 lbs trolling motor.
