The like-new batteries were purchased by customers who mistakenly bought the wrong capacity or incompatible batteries for their applications. We assure you that all like-new batteries are rigorously checked and tested to verify functionality and quality before delivery (only a few have minor scratches on the surface). All like-new batteries qualify for the same 5-year warranty as our new batteries. Order with confidence knowing we stand behind the quality.

【Grade A LiFePO4 Cells】LiTime 51.2V 100Ah LiFePO4 batteries use UL-certified Grade A LiFePO4 Cells that offer higher energy density, better performance, and greater power. With a BMS system that auto balances cell consistency, you can expect a longer battery lifespan, that's more than 10 years lifespan, with up to 4000-15000 cycles. Backed up with FCC, CE certificates, and a 5-year warranty.

【Unbeatable Energy Density】LiTime 51.2V 100Ah LiFePO4 battery boasts an incredible energy density of around 53.38Wh/lb, up to 3-4 times that of lead-acid batteries of the same size. It is equivalent to four 12V 100Ah LiFePO4 batteries in series (or even eight 12V 100Ah AGM batteries), providing a maximum energy of 5.12kWh.

【10 Days Nonstop Power Supply】With LiTime 51.2V 100Ah lithium batteries, you can enjoy up to 10 days of uninterrupted power for your home (assuming a minimum daily usage of 0.5kWh) and avoid any grid outages. With 100A BMS and 5120W output, you can even power heavy-duty appliances such as air conditioners and dryers at the same time. Plus, you can connect them in parallel to increase power output (max. 4P for 20.48kW).

【4X Faster Charging】You can charge LiTime 51.2V 100Ah battery in just 5 hours with a 20A current, not 20 hours with traditional batteries. LiTime delivers reliable and efficient charging, so you can spend less time waiting and more time using your devices.

【1/2 Space Saving】 51.2V 100Ah's compact design saves 50% of the space compared to traditional batteries. Easy to install and use, equivalent to group 8D battery size, it's the perfect solution for those who want to save space without compromising on performance.

【Fast Delivery & Exceptional Service】At LiTime, we are committed to providing you with the best service possible. Our batteries are shipped from US local warehouses and typically arrive within 2-5 working days (depending on inventory). You can also expect professional technical support and quick feedback from our online customer service team within 24 hours.

FAQ

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.

Can I use LiTime LiFePO4 Lithium batteries as starting batteries?

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.

Can I charge LiTime LiFePO4 lithium batteries with solar panels?

Yes, you can charge LiTime LiFePO4 lithium batteries with solar panels. You should size your charge controller based on the voltage and current output of your solar array setup. That will ensure that your charge controller can process and regulate the power coming from your solar panels. Take a 24V MAX. 22 amps output solar system for example. You would need a solar charge controller that can handle 24 volts and 27.5 amps (125% of your max current output).

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

LiFePO4 batteries can safely charge between 32°F to 113°F (0°C to 45°C). LiTime 12V 100Ah TM & 230Ah LiFePO4 batteries include the 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.

How do I store LiTime LiFePO4 lithium batteries?

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
