    Fantastic easy to charge and hook up!

    We received the battery with no issues, right on time. We charged it up over night and hooked it into our invertor the next day. Everything went smoothly and we are very pleased with the power accessible.now even with the rainy days. Yay!!

    I received the battery in 4 days

    I haven't had the chance to use the battery yet but the quality of the case and the weight was much less than the old 6 volt batteries plus the energy storage should be hugely beneficial.

    FAQ

    Q: Are LiTime LiFePO4 batteries safe?

    A:Are LiTime LiFePO4 batteries safe? Yes. LiFePO4 is an inherently safe chemistry and the most stable lithium-type battery on the market. LiTime lithium cells are UL certified for the highest safety and sustainability standards. All LiTime LiFePO4 batteries come with an internal Battery Management System which protects against under-voltage during discharge, over-voltage during charge, over-current during discharge, over-temperature during charge and discharge, and short-circuit protection – protects battery cells from damage. Additionally, LiTime LiFePO4 Lithium batteries have been tested to be free from the risk of fire, and electric shock in harsh environments.

    Q: Can I use LiTime LiFePO4 Lithium batteries as starting batteries?

    A:

    No. LiTime LiFePO4 lithium batteries are not intended to be used as starting batteries but energy storage, please do not use them to start any devices.

    For more information to tell the differeces among these 2 types batteries, read on our blog Deep Cycle VS Starting Battery.

    Q: Can I charge LiTime lithium batteries with solar panels?

    A:

    Yes, you can charge LiTime lithium batteries with solar panels. Here are 3 reliable ways to charge

    1. Using Solar Panels

    The LiTime 12V 400Ah battery can be fully charged by in one day (with effective sunshine 4.5hrs/day) by 1200W solar panels. It may take more than one day to fully charge the battery by ≥1200W solar panels since the duration and intensity of light would be a great factor for their charging efficiency.

    2. Generator/Alternator

    If the alternator or generator supports DC output, a DC-to-DC charger is needed to connect the battery to the generator; if your alternator or generator supports AC output, please add a suitable battery charger to connect the battery and the generator according to our recommendations.

    The Recommended Charging Voltage: 14.2V - 14.6V. The Recommended Charging Current: ① 80A (0.2C): the battery will be fully charged in around 5 hrs to 100% capacity; ② 200A (0.5C): the battery will be fully charged in around 2 hrs to around 97% capacity.

    3. LiFePO4 Smart Chargers

    To charge 12V battery, it is recommended to use 14.6V battery charger.

    The Recommended Charging Voltage: 14.2V - 14.6V.

    The Recommended Charging Current: ① 80A (0.2C): the battery will be fully charged in around 5 hrs to 100% capacity; ② 200A (0.5C): the battery will be fully charged in around 2 hrs to around 97% capacity.

    Related reading: Can I Charge LiFePO4 batteries with a Normal Charger?

    Q: Can I charge LiTime LiFePO4 lithium batteries in cold weather (under freezing temperatures)?

    A:

    LiFePO4 batteries can safely charge between 32°F to 113°F (0°C to 45°C). LiTime 12V 100Ah TM & 230Ah LiFePO4 batteries include low-temperature charging protection which will automatically cut the battery charging off when the cell temperature is lower than 32℉, thus preventing the battery cells from damage when charging under the freezing point.

    Q: How do I store LiTime LiFePO4 lithium batteries?

    A:

    It is recommended to store LiTime LiFePO4 batteries at 50% state of charge (SOC). If the batteries are stored for long periods, cycle the batteries at least every 6 months. Recommended storage environment: 10℃~35℃ (50℉~95℉), 45%RH~75%RH

    Q: What is the typical application for a 12V 400Ah lithium battery?

    A:

    Typical applications include RVs, marine vessels, solar home energy storage, off-grid power systems and industrial equipment.

    Q: Can this battery be used in series to build a 48-volt system?

    A:

    Yes. LiTime 12V deep cycle lithium batteries can be connected 4 in sereis to create a 48V battery system.

    Note: DO NOT connect batteries with different chemistries in sereis or parallel.
