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 6Ah LiFePO4 Battery FAQ

The Motawill 12v 6Ah LiFePO4 Battery offers an impressive lifespan, typically ranging from 4000 to 15000 life cycles. This longevity translates to a usage span of around 10 years or even more, depending on your specific usage patterns. In comparison, traditional lead acid and AGM batteries typically provide only 300 to 500 life cycles before experiencing a substantial reduction in their capacity.

Despite the higher upfront cost associated with a LiFePO4 battery, it's important to consider the substantial long-term savings it offers. This extended lifespan makes it a cost-effective choice, ensuring you get the most out of your investment over time.

Selecting the right size of a Motawill 12v 6Ah 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.

For specific dimensions, please consult the battery's specification sheet. If you have additional questions or unique requirements, feel free to contact us via email for personalized assistance.

Yes. LiFePO4 is an inherently safe chemistry and the most stable lithium-type battery on the market. Motawill 12v 6Ah LiFePO4 Battery are UL certified for the highest safety and sustainability standards. All Motawill 12v 6Ah LiFePO4 Battery 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, Motawill LiFePO4 Lithium batteries have been tested to be free from the risk of fire, and electric shock in harsh environments.

Yes, you can charge Motawill 12v 6Ah LiFePO4 Battery 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 as example. You would need a solar charge controller that can handle 24 volts and 27.5 amps (125% of your max current output).

The Motawill 12V 6Ah LiFePO4 Battery is designed to be charged safely within a temperature range of 32°F to 113°F (0°C to 45°C). This range ensures optimal performance and longevity of the battery.

Additionally, our LiFePO4 batteries feature a low-temperature charging protection mechanism. When the cell temperature drops below 32℉, this protection function is automatically activated. It will interrupt the charging process to prevent potential damage to the battery cells when charging in freezing conditions.

In the event that you need to charge the battery in extremely cold temperatures, we offer a solution for emergency use. By pressing the low-temperature protection button twice, the Battery Management System (BMS) will temporarily override the low-temperature protection. This allows you to charge the battery under freezing conditions. However, it's important to note that this is not the recommended operating method and should only be used when absolutely necessary.

Your battery's safety and performance are our top priorities, so please use this emergency feature sparingly and under extreme conditions only. If you have any further questions or concerns, feel free to contact us for additional guidance.

It is recommended to store Motawill 12v 6Ah 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

    So I previously trashed this product in a similar way to the other 1 star review due to my lack of knowledge on how these batteries work. These batteries have internal battery management systems (BMS) which cutoff the current at 10V and cause the batteries to read 0V. I was under the impression this was either a “recommended cutoff” on the datasheet or the BMS would cut the current and then restart a moment later like many other BMS’s do. When looking online, many people stated the drop to 0V was part of the protection circuit and was permanent: This isn’t true!

    These batteries are designed to go into a sleep mode when they reach 10V and will wake up when voltage is applied from a charger. This is actually an incredibly useful feature for my application of using these as a portable power bank for heated motorcycle gear. I no longer need to worry about over discharge. I can just let the internal cutoff activate if the cells get too low (obviously this isn’t preferred, but will work in a pinch if I run the batteries longer than normal).

    Now here’s the issue: The charger I’m using, which is a smart charger for sealed lead acid (SLA) and Li Ion batteries used in cars, needs to detect the voltage coming from the battery to turn on charging. As a result, it does not send out any voltage of its own and will not wake up a sleeping battery. To turn the batteries back on, I VERY quickly tapped a 9v battery across the terminals of the battery (another 12v battery would have been better), positive to positive and negative to negative. This supplied the needed voltage to wake up the BMS and allow the 11.2 or so volts remaining to be present on the terminals once again. Now my smart charger could detect the battery and charge it like normal.

    Yes, the battery had 11.2V when the cutoff is 10V. This is not a defect in the BMS, rather, the voltage will sag under load to 10V, the cutoff will activate, and when the battery is woken up it will once again read the non-sagging “open circuit” voltage as there is no load any more.

    Overall I’m very happy with the 3 batteries I bought which arrived with identical voltages, perfect for parallel configurations. They have more power than I was expecting and should easily run my heated gear for 2+ hours on max heat. Being able the use a standard SLA charger and having an automatic low voltage cutoff makes these a versatile power source for many projects. Just make sure you have a way to “wake up” a battery that has reached the low voltage cutoff; either another battery or a non-smart charger.

    Here’s the result of my discharge test for those who are curious about how much power these have. I’m using 3 batteries in parallel for roughly 18Ah of capacity (Series configurations are not recommended without a BMS, and even then, these batteries have internal BMS’s so most people wouldn’t recommend series configurations at all. I’ll leave you to decide if you want to run series or not). I was powering a heated vest which consumes 5 amps at max heat and has 5 power settings. You can very roughly estimate that each power setting draws 1 amp (setting 1 is 1 amp, setting 2 is 2 amps, etc.), but the actual current draw is likely higher based on my testing. Here’s the results:

    Heat 1 for 1.5 hours
    Heat 2 for 3 hours
    Heat 4 for 2 hours

    At this point the low voltage cutoff activated around 6.5 hours after I started running the heater! Obviously this isn’t even remotely scientific as I used different settings and the only power setting that I can check the current draw accurately on is setting 5 which draws 5 amps (other settings use PWM so my cheap multi-meter is pretty useless). I’m pretty happy with these results and this pack should power my gear for a few hours with medium heat settings.
