FAQs

How long does a 12V 100Ah Bluetooth 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 100Ah Mini Bluetooth battery and connect a 50W lamp and a 50W speaker, the runtime will be:
1280Wh / (50W + 50W) = 12.8 hours

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

How do I download the WattCycle App?

You can search for WattCycle on Google Play or Apple Store, and you will find the app named WattCycle.

What data can I view through the WattCycle App?

After you connect the battery, you can see the state of charge (SOC), temperature, voltage & current, control battery charging and discharging, and warnings on the data center interface. In the advanced settings, you can set the maximum charge and discharge current and temperature.

Can this 12V 100Ah Mini battery be placed under the seat of the caravan​?

Due to this mini battery's height of 208mm, you cannot place it vertically upright under a caravan seat. Instead, you will need to position the battery sideways (switching the height to 138mm).

What’s the difference between the 12V 100Ah battery, 12V 100Ah Mini bluetooth battery, and 12V 100Ah Mini battery?

Size Comparison:

  • 12V 100Ah Standard Battery Dimensions: L260 × W168 × H209mm
  • 12V 100Ah Mini Battery & 12V 100Ah Mini Bluetooth Battery Dimensions: L229 × W138 × H208mm

Functional Differences:

  • 12V 100Ah Standard Battery & 12V 100Ah Mini Battery:
    Low-Temperature Protection: Automatically stops discharging when temperatures drop below -20°C to prevent damage.
    No Bluetooth Connectivity.
  • 12V 100Ah Mini Bluetooth Battery:
    Low-Temperature Protection: Same as above.
    Bluetooth Monitoring: Allows real-time tracking of battery status (e.g., voltage, charge level, temperature) via a smartphone app.
How should I discharge my WattCycle 12V 100Ah Mini LiFePO4 smart battery in Sub-Zero temperatures?

No worries! All WattCycle LiFePO4 batteries feature built-in low-temperature protection, allowing safe discharge even at temperatures as low as -20°C. This means that devices that are operated in freezing temperatures can continue to be reliably supplied with power.

What’s the maximum output energy I can get from 16 WattCycle 12V 100Ah Mini batteries?

20.48kWh! You can connect 16 WattCycle 12V 100Ah Mini deep cycle batteries in a 4S4P configuration (4 in series, 4 in parallel) to create a 48V 400Ah battery system. This system can continuously discharge 400A and deliver 20.48kWh of energy, making it ideal for home energy storage or high-demand off-grid applications.

Best in class LiFePO4 battery

There are many brands to choose from but WattCycle provides a great balance of build quality, features, and price. I was very impressed that the company seems to really stand behind its products. All-in-all, I am very satisfied.
