Battery Emptying Faster Than Expected? Try This.


On a few of our BT modules, the idle / power-off current drain is larger than normal, and the battery is discharged when not in use.You will notice this after leaving the RaceTracker for 1-2 weeks without use it will have fully drained itself, or it arrives completely empty from the factory. There are possible DIY fixes, but TBS recommends to ship you a replacement unit instead. Please contact our customer support!


The Fix:


  • The circuit needs to be modified using a PFET transistor to cut off power to the Battery Monitoring section.
  • Add switch onto the power line from the battery


If you don't know how that works, please don't try to do it yourself. Open a ticket with our customer service instead.
