Why Can’t My Pro Battery Establish a Communication Connection with the DC Home APP?
Unfortunately, when your Pro lithium battery can not establish a communication connection with the DC Home APP, there could be a variety of reasons behind the problem. The issues might stem from a damaged bluetooth or external factors unrelated to the lithium battery itself. It may require some trial and error as well as battery troubleshooting to uncover the underlying cause.
What Are the Factors Affecting Pro Battery’s Communication with DC Home APP?
1. The battery is in undervoltage protection mode, causing the Bluetooth inside the battery to be turned off.
2. The battery has already communicated with DC Home APP on another mobile phone or with Renogy One M1/Renogy One Core device.
3. The DC Home APP is not updated to the latest version.
4. There is electromagnetic interference where the battery is located.
5. The distance between the phone and the battery is too far.

1. Exclude BMS undervoltage protection. Measure the open-circuit voltage (Voc) of the battery and judge based on the following criteria:
- For 12V battery: Voc < 10V
------Possible Results------
Positive: The battery is in undervoltage protection, and the BMS and internal communication module are not working. Activate the battery by using a lithium battery activation charger.
Negative: The battery is not in undervoltage protection. Please try other steps.
2. Exclude the possibility of the communication channel being occupied. Eliminate the possibility that the battery is paired with other mobile devices.
------Possible Results------
Positive: The battery is paired with other devices. Unpair the existing connection and pair it again with the intended device.
Negative: The battery is not paired with other devices. Please try other steps.
3. Exclude the possibility of a low DC Home version. Update the DC Home APP to the latest version and then search and connect to the battery in the app.
------Possible Results------
Positive: After the update, communication is successful.
Negative: Even after the update, communication is still not possible. Please try other steps.
4. Exclude electromagnetic interference. Please check whether there is electromagnetic interference where the battery is located, as it can affect the product's communication function.
------Possible Results------
Positive: Electromagnetic interference has been ruled out, and communication is successful.
Negative: Confirming no electromagnetic interference but still unable to communicate. Please try other steps.
5. Exclude distance factors. Being too far can cause Bluetooth to have an unstable connection. Please place the phone within a 2m range of the battery for connection.
------Possible Results------
Positive: Normal communication within a 2m range. Considered a normal product.
Negative: Still unable to communicate within a 2m range. Please try other steps.
If all the influencing factors mentioned in steps 1, 2, 3, 4, 5 are ruled out, it can be determined that the product itself is faulty.
