[Customer Emails]

A customer asked: Is it normal for the lights on the battery pack to go on and off during treatment?

[tallymarks]

Yes, it is absolutely normal for the LED lights on the battery pack itself to turn on and off during BFST treatments!

There are LED lights on the controller, or the part of the cord that connects the BFST and the battery together, with the white piece of plastic and power button. As long as the lights on the controller remain on throughout the treatment, it does not matter if the lights on the battery pack turn on and off.
