FAQs

Is the 600A overcurrent protection on the 12V 280Ah Mini battery safe?

Of course, the WattCycle 12V 280Ah Mini deep cycle LiFePO4 battery is safe, with 600A current only supported for 1.2 seconds. This overcurrent protection ensures that in the event of an overload or surge, the battery will be safely disconnected to prevent any harm.

The BMS (Battery Management System) constantly monitors the battery's health and can cut off power if necessary, so you don’t have to worry about overheating or permanent damage during high-demand situations. This level of protection ensures both the battery's longevity and your peace of mind, making it a reliable choice for various applications.

How long will a 280Ah battery last?

Battery runtime is influenced by multiple factors, including battery capacity, connected load, and the battery’s condition. For example, a new battery performs better than a used one, as its capacity slightly decreases with repeated charge cycles. However, you can estimate runtime using a simple formula based on power consumption and battery capacity:

Runtime (hours) = Battery Capacity (Wh) / Total Device Power Consumption (W)

Example:
If you have a 12V 280Ah Mini battery and connect a 50W lamp and a 50W speaker, the runtime will be:
3584Wh / (50W + 50W) = 35.84 hours

This straightforward formula helps estimate runtime under different loads. Always consider real-world factors like temperature and battery aging for more accurate predictions.

Does the 12V 280Ah Mini LiFePO4 battery come with certification?

Yes, the 12V 280Ah Mini LiFePO4 battery is fully certified to meet global safety and quality standards. It comes with the following certifications:

  • SDS (Safety Data Sheet): Ensures safe handling, storage, and transportation of the battery.
  • UN38.3: Verifies compliance with transportation safety standards for lithium batteries.
  • FCC: Certifies that the battery meets electromagnetic interference (EMI) regulations.
  • CE: Indicates the battery conforms to European Union safety, health, and environmental protection standards.
  • RoHS: Ensures the battery is free from hazardous materials, in compliance with environmental regulations.
  • UL1642: Verifies that the battery meets rigorous safety standards, ensuring safe operation and protection against risks.

These certifications highlight the quality, safety, and environmental responsibility of our battery, giving you confidence in its performance and reliability.

How many kWh is a 280Ah battery?

3584Wh!

WattCycle 12V 280Ah Mini battery with 200A BMS provides 2560W output power and 3584Wh energy storage.

How to charge WattCycle 12V 280Ah Mini deep cycle LiFePO4 battery?

WattCycle LiFePO4 Batteries are straightforward to charge. The following 3 charging methods are recommended by WattCycle:

1. Dedicated 12V LiFePO4 Battery Chargers

  • Charging Recommendations:
  • Recommended Charging Voltage: 14.6V ± 0.2V
  • Recommended Charging Current:
  • 60A (0.2C): Charges the battery to 100% capacity in approximately 5 hours.

2. Solar Panel & Solar Charge Controller

  • Harness solar energy! With 4.5 hours of effective sunlight per day, a 1200W solar panel system can fully recharge your battery in a single day.
  • Solar Panel Flexibility: Larger solar panels (e.g., over 1200W) can also charge your battery, though charging times may vary depending on sunlight intensity and duration.
  • Critical Component: Always use a solar charge controller to regulate voltage and protect the battery.

3. DC-DC Generator/Alternator
Compatible Power Source is Key:
Ensure your generator or alternator has a DC output. In this case, a DC-DC charger is required to connect it to the battery.
AC Output Option: If your generator/alternator uses an AC output, refer to our recommendations for a compatible battery charger to interface with your battery.

Charging Recommendations:

  • Recommended Charging Voltage: 14.6V ± 0.2V
  • Recommended Charging Current:
  • 60A (0.2C): Charges the battery to 100% capacity in approximately 5 hours.

Runs my appliances for days without a recharge. Overcurrent protection is a nice safety feature. Looking forward to the Bluetooth model.

USER MANUAL

Tested, Reviewed, and Approved by YouTubers

They are packing the power up NICE and DENSE inside of this battery, what I found out is that this battery's low voltage cut-off is at 9.2V instead of the typical 10V that we've been used to for the past couple of years. They are packing a lot of energy into a very small space.

YouTuber @Temporarily Offline Ham Radio

That's a lot of power in a small format like this, very COOL! That's beyond the 300Ah, it held up real nice for the capacity test. I really like it!

YouTuber @DIY Homestead Projects

It looks pretty large, but a 300Ah (280Ah) battery looks a bit small size and indeed it is smaller than you would expect. And, that's why they're calling it a mini battery. Anyway, the battery pretty much has the capacity, the answer is it ran that heater for over 6.5 hours straight!

Youtuber @Solar Power Edge

It is absolutely incredible how tiny this thing is. I know this thing doesn't look real pretty, this is a great way to save a ton of money, this gives you a big big big power in a very small package that you can move around.

Youtuber @Texas Prepper Projects

WattCycle 12V 300Ah (280Ah) Mini battery, this thing is absolutely insane at 3840Wh (3584Wh) worth of capacity. This thing is a beast of a battery in a very very compact format.
