Firstly, your inverter must be within the range of inverters compatible with my battery. Then after connecting the battery to the inverter and establishing communication, you can directly view the battery parameters through the inverter. If you are unsure whether your inverter is compatible with our battery, please contact me to confirm! 

You can also connect to the computer via RS485/RS232/CAN cables and download the software to view the battery parameters on the computer.

This means with these options, you no longer need to use a Bluetooth app to view battery data.

However, for customers who prefer viewing battery data on their phone, I recommend still purchasing batteries with Bluetooth functionality. This is because you can view data through the above two methods on the inverter or computer, while also using a Bluetooth app on your phone.

Battery Testing Videos ↓

Please note: The heating function is automatic and not manual. The heating module is an independent module that is not controlled by the Bluetooth app. Therefore, the heating function cannot be adjusted through the Bluetooth app. The heating function will only automatically activate when the ambient temperature drops below 0°C (32°F).

Intelligent temperature control: The self-heating function automatically activates in environments between -20°C to 5°C (-4°F to 41°F).
Precise Adjustment: Automatically stops heating when the battery reaches 5°C/41°F and begins normal charging.
External Power Supply: Uses the charger/controller's current rather than consuming the battery's own energy for more flexibility and efficiency.  
Notes on Use: The battery must be placed below 0°C for self-heating to activate automatically. Please check this video for more details: https://www.youtube.com/watch?v=GA_DfhawRpw&t=14s

Auto-balancing Function: Easily connect multiple batteries in parallel(4S/4P)with the auto-balancing function, improving the average charging efficiency for your batteries in the long term.
