    Nice Battery

    We bought this battery to replace our camper's aging lead-acid batteries. So far it is doing great and powers the jacks and slide out just fine. We did have to reconfigure the battery compartment and get an upgraded charger. We haven't used it yet boondocking, but in testing it ran the refrigerator for a day and still had a charge. The benefits of lithium over lead-acid will become more apparent during our trip to Alaska where we may do many boondocking stops.

    I'm Happy With This Product

    The battery arrived well packaged (picture 1) in just two days. It includes a product manual (picture 2), which I like, and a resealable bag to store the manual, which is very useful in my situation. The terminal hardware was clearly labeled and attached to the document bag (picture 3) so it didn't get lost in the packing. The battery is large because of its capacity, but it fit into my existing battery compartment with no problem (picture 4).

    I chose a lithium-based battery, because these days they're actually less expensive than lead-acid batteries. Lithium batteries are also much lighter. This battery weighs 63 pounds, but it has roughly twice the usable capacity of my old lead-acid batteries, which weighed a total of 200 pounds. I chose the 300AH (amp hour) model because I run a desktop computer in my bus, and I need enough stored power to run it at night or on cloudy days when my solar panels aren't delivering much power. Starting with a full charge, this battery can run my computer, monitor, speakers, lamp, and a fan for 30 hours or more while still keeping my phone, cameras, tablet, and other gadgets charged.

    I also chose Li Time because they seem to be working hard to constantly improve their products and their customer service, and I believe in encouraging companies that try. I don't have the equipment to do a full technical review, but you can find such reviews online. According to those reviews, the build quality and performance of Li Time batteries are very good for the price.

    I would buy from Li Time again, and I would recommend them to others.

    FAQ

    Q: Are LiTime LiFePO4 batteries safe?

    A: 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 LiFePO4 lithium batteries with solar panels?

    A:

    Yes, you can charge LiTime LiFePO4 lithium batteries with solar panels.  Here are 3 recommended ways to charge LiFePO4 lithium batteries.

    1. Using Solar Panels

    The LiTime 12V 300Ah 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 60A (0.2C): the battery will be fully charged in around 5 hrs to 100% capacity; ② 150A (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 60A (0.2C): the battery will be fully charged in around 5 hrs to 100% capacity; ② 150A (0.5C): the battery will be fully charged in around 2 hrs to around 97% capacity.

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

    A:

    LiFePO4 lithium 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.

    Related reading: What is low-temperature protection to lithium batteries?

    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.

    Q: How many LiTime 12V 300Ah lithium Batteries can I connect at most?

    A:

    he 12V sereis batteries support versatile connections, including series, parallel, and series-parallel connection. You can connect 12V 300Ah up to 4 batteries in series, 4 in parallel, or 16 in the series-parallel connection to create 40.96kW capacity and 61.44kWh energy.

    Batteries of the same model and similar capacity are required.

    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
