If you are getting a "low battery" alert on your Flame Boss® controller. There is no internal battery in the Flame Boss® controllers. This warning is intended for users who are using our FB Rechargeable Battery Pack. When getting this alert when using the FB 12V DC power supply it usually means the controller is getting less than 1 amp of power. Are you plugging the FB power supply into an extension cord? Please try plugging the controller into a different outlet and/or extension cord.
