FAQ
Yes. Our 200A BMS protects against charging or discharging in unsafe temperatures.
- Charge cutoff: 0 °C – 45 °C
- Discharge cutoff: –20 °C – 60 °C
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 hoursThis straightforward formula helps estimate runtime under different loads. Always consider real-world factors like temperature and battery aging for more accurate predictions.
You can search for WattCycle on Google Play or Apple Store,and you will find the app named WattCycle.
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.
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.
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.
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 a48V 400Ah battery system. This system can continuously discharge400Aand deliver20.48kWh of energy, making it ideal for home energy storage or high-demand off-grid applications.
The 12V 100Ah MINI Bluetooth LiFePO4 Battery, equipped with an integrated Bluetooth module, enables convenient monitoring of the battery status using your smartphone through the App.
This application is independently developed and designed by Shenzhen Wattcycle Power Co., Ltd. lt specializes in monitoring lithium batteries, providing real-time status readings such as the voltage of each battery series charging and discharging current, alarm prompts, protection status, etc. This allows users to clearly understand the health status of lithium batteries and ensure their safe use.
You can download the app by scanning the QR code in the user manual.
Yes, it does. It is recommended to charge it between 32℉ (0℃) and 122℉ (50℃ ).
Expand your power options! You can connect up to four (4) WattCycle 12V 100Ah lithium batteries in series or parallel configurations (denoted as 4S or 4P). This allows you to increase the voltage (series) or capacity (parallel) of your battery system to meet your specific needs.
For safe and optimal performance, please follow these connection guidelines:
1) Brand:Only connect WattCycle brand batteries (ensure compatibility).
2) Type: All batteries must be lithium type.
Voltage: All batteries must have the same voltage (12V in this case).
3) Capacity: All batteries must have the same capacity (100Ah).
4) BMS: Ensure all batteries have the same Battery Management System (BMS).
5) Purchase Date:Ideally, connect batteries purchased within 3-6 months of each other (for similar performance characteristics).
Not following these guidelines could damage your batteries.
We recommend consulting a qualified professional for assistance with battery connection.
20.80kWh.
With 4S4P, this allows you to quadruple the voltage (series) and capacity (parallel) of your battery system for maximum output energy.
Then the maximum output energy you get is equal to 20.80kWh. (12.8V*4*100Ah*4=20.80kWh)
