bluetooth module damage

[GotSmart]

My renogy bluetooth battery could not connect to dc home app. could not find the device. I open the top up and found that bluetooth module is corroded with salt and water, I guess. could not find the replacement part. The battery still charge and discharge but there is no way I can monitor except with voltmeter. Any advice? I prefer reestablishing bluetooth capability.

There is a aftermarket monitor available. I believe it’s about $20. 

You could always contact Renogy because they are all about customer service.
