Free Shipping to Lower 48

Motawill will ship your batteries for free anywhere in the lower 48 US States. Batteries ship UPS ground freight and will arrive in 5-7 days in most of the US. You will receive an email with a tracking number after your order ships. The USPS does not allow batteries to be shipped to Post Office boxes (PO Box). Please use a street address. Larger batteries (over 300 watts) require hazmat shipping. We pay the cost of Hazmat and freight (typically $90 to $150 a battery). You pay $0 for shipping. Shipping to Alaska and Hawaii is higher due to federal law that requires that batteries ship Air Freight and have Hazmat protection. Shipping to Canada includes duty, GST, and import fees.

For non-quality issues, customers may ask for product replacement or return within 30 days after receiving it. A 10% processing fee will be applied but we can prevent it for the customer if a replacement order is received. The customer is also responsible for the return shipping cost of $150. Motawill will provide a return shipping label, and the designated carrier will collect the return package. The customer may also self-return or arrange the return shipment by himself.

12v 50Ah LiFePO4 Battery FAQ

When replacing your old batteries with our 12V 50Ah LiFePO4 Battery, follow these simple steps:

Remove the Old Batteries: Begin by carefully taking out your old batteries from their housing or compartment.

Position the New Battery: Place our 12V 50Ah LiFePO4 Battery in the same location where the old batteries were situated. Ensure that it fits securely and aligns with the previous setup.

Reconnect the Cables: You can reuse the same cables and connectors that were originally connected to your previous batteries. Reattach these cables to the terminals of the LiFePO4 Battery. Make sure to connect the positive (+) cable to the positive terminal and the negative (-) cable to the negative terminal.

By following these straightforward steps, you can easily transition to our 12V 50Ah LiFePO4 Battery, enabling a more efficient and cost-effective power solution for your needs. If you have any questions or require further assistance during the installation process, don't hesitate to reach out to us for support.

The Motawill 12V 50Ah LiFePO4 Battery is renowned for its remarkable lifespan, spanning an impressive range of 4000 to 15000 life cycles. This extended longevity translates to a usage span of approximately 10 years or potentially even longer, contingent upon your specific usage patterns.

Charging your 12V 50Ah LiFePO4 Battery is a straightforward process, thanks to the advanced technology and robust built-in battery protection system. Here's how to charge it:

Select a Charger: You have the flexibility to use a standard charger with our 12V 50Ah LiFePO4 Battery. However, in specific situations, such as when rapid or specialized charging is required, you may opt for a dedicated lithium charger.

Connect to Power: Plug your chosen charger into an appropriate power source or outlet.

Battery Connection: Use the charger's cables to connect it to the battery. Make certain that you correctly match the positive (+) cable to the positive terminal on the battery and the negative (-) cable to the negative terminal.

Monitor Charging: While the battery is charging, you can monitor the progress. The built-in battery protection system ensures the battery is safeguarded against overcharging and other potential issues that could lead to damage.

Selecting the right size of a Motawill 12v 50Ah LiFePO4 Battery depends on your specific priorities and needs. Motawill LiFePO4 batteries offer roughly double the usable capacity compared to lead acid and AGM batteries.

We strongly advise against combining a 12V 50Ah LiFePO4 Battery with a lead acid battery pack. Such a configuration may lead to damage to the batteries and should be avoided.

When wiring or connecting batteries, it is essential to match batteries that are of the same type (in this case, lithium), possess the same capacity in Ampere-hours (Ah), have the same voltage (V), and are from the same brand. Mixing different types of batteries, especially lithium and lead acid, can result in operational issues and potential harm to the batteries.

Absolutely. Motawill 12V 50Ah LiFePO4 Battery are designed with safety as a top priority. LiFePO4 (Lithium Iron Phosphate) is known for its inherent safety, making it one of the most stable lithium-based battery chemistries available. In addition to this inherent safety, our batteries undergo rigorous testing and adhere to the highest industry standards:

UL Certification: Motawill 12V 50Ah LiFePO4 Battery are UL certified, meeting the most stringent safety and sustainability standards.

Battery Management System (BMS): Each battery is equipped with an internal Battery Management System that provides protection against various potential issues. This includes safeguards against under-voltage during discharge, over-voltage during charge, over-current during discharge, over-temperature during charge and discharge, and protection against short-circuits. This comprehensive BMS ensures the safety and longevity of the battery.

Harsh Environment Testing: Motawill LiFePO4 Lithium batteries have been rigorously tested to confirm their safety and reliability in challenging conditions, ensuring they are free from the risk of fire and electric shock.

Certainly, you can charge your Motawill 12V 50Ah LiFePO4 Battery using solar panels. Here's what you need to consider:

Sizing Your Charge Controller: Ensure that you choose an appropriate charge controller based on the voltage and current output of your solar panel array. The charge controller is essential for regulating and processing the power generated by your solar panels. For instance, if you have a 24V solar panel system with a maximum output of 22 amps, you should select a solar charge controller capable of handling 24 volts and, for safety, around 125% of your maximum current output, in this case, about 27.5 amps.
By correctly sizing your charge controller, you can efficiently harness the power of your solar panels to charge your LiFePO4 battery, making it an eco-friendly and sustainable energy solution for your needs.

The Motawill 12V 50Ah LiFePO4 Battery is designed with specific operating temperature ranges for both charging and discharging:

Discharging: This battery can safely operate within a temperature range of -4℉ to 140℉ (-20℃ to 60℃).

Charging: The recommended operating temperature range for charging is 32℉ to 113℉ (0℃ to 45℃).

For the best performance and to maintain battery health, it's advisable to use this battery in an environment with a temperature of approximately 73.4 ± 9℉ (23 ± 5℃).

It is recommended to store Motawill 12v 50Ah LiFePO4 Battery 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

Upon receiving your battery, it's important to follow these guidelines to ensure its proper handling and optimal performance:

Check State of Charge (SOC): Be aware that the battery may have a low State of Charge (SOC) when it arrives, which is common due to the transportation and storage process.

Immediate Charging: To safeguard against over-discharge, we recommend charging the battery as soon as possible upon receipt. This will help prepare the battery for use and maintain its performance.

Storage Preparation: If you intend to store the battery for an extended period without use, it's advisable to charge it to a SOC of 30% to 50%. Additionally, perform a maintenance charge every three months during storage. These measures will help preserve the battery's functionality and performance over time.
