    The 12V 100Ah Pro lithium leisure battery is engineered to handle harsh climates. With low-temperature cut-off protection, charging automatically stops below 0℃ to protect internal cells, resuming when temperatures rise above 5℃. It also halts discharging at -20℃, ensuring safe operation even in winter camping or high-altitude travel.

    Expandable Energy for Greater Needs

    Need more power? Connect up to 4 batteries in series and 4 in parallel (maximum of 16 units) to create a massive 48V 400Ah system with 20,48kWh of capacity. Whether you’re powering a motorhome, a remote cabin, or an off-grid home, this scalability gives you the freedom to design an energy solution that matches your lifestyle.

    Multiple Charging Options for Total Flexibility

    No matter where you are, keeping your LiFePO4 deep cycle battery charged is easy. Choose from: Solar panels + MPPT solar charge controller for renewable off-grid charging; 14,6V 20A LiFePO4 battery charger for fast home charging; Generator charging for backup in remote locations.With three charging methods, you’ll never run out of power—whether at home or on the road.

    FAQ's

    How do I charge the WattCycle LiFePO4 deep cycle battery?

    You can charge it with a LiFePO4 battery charger, solar panels + MPPT solar charge controller, or generator/alternator (with the correct voltage regulation). For optimal performance, use a charger specifically designed for LiFePO4 deep cycle batteries with the correct charging profile.

    How many solar panels can charge a 12V 100Ah battery​?

    To charge a 12V 100Ah lithium battery from 100% depth of drain in 4.5 peak sun hours, approximately 400 watts of solar panels and an MPPT charge controller are required.

    Can different models of WattCycle 12V 100Ah batteries be connected in series or parallel?

    Absolutely not! For safely connecting WattCycle LiFePO4 batteries in series or parallel, four strict rules must be followed:

    • Same Brand (Manufacturer)
    • Same Voltage (12V)
    • Same Current (Capacity: 100Ah)
    • Purchased Within 6 Months

    Why Mixing Different Models Is Unsafe:

    • Even if two batteries are labeled "12V 100Ah," different models may have variations in internal resistance, cell chemistry, or BMS (Battery Management System) behavior.
    • These differences can cause imbalanced charging/discharging, leading to overheating, reduced efficiency, or permanent damage.
    Is the battery safe for marine and outdoor use?

    Absolutely. The WattCycle 12V 100Ah Pro lithium leisure battery is equipped with a 110A BMS for protection against over-voltage, over-current, over-discharge, short circuits, and temperature extremes. The casing is built for durability, making it suitable for both marine and off-grid outdoor applications.

    Does the battery require maintenance?

    No. Unlike lead-acid batteries, LiFePO4 deep cycle batteries do not require regular maintenance or water refilling. Simply store and operate within the recommended voltage and temperature ranges.
