SMC Racing Precision Lipo Alarm

Introducing the Precision Lipo Alarm, designed to get a more precise cutoff then an ESC. When running the Traxxas or Arrma ESC which are known to have the cutoff set to low and not adjustable this is a must have item if you are interested in getting maximum cycle life out of your packs.

With standard Lipo alarms the alarm is set at the desired cutoff but the alarm doesn’t account for voltage drop which occurs under heavy acceleration. This means the normal alarms will go off when the pack/cells haven’t reached the desired cutoff voltage. The SMC Precision Alarm has been designed to have a delay before the alarm goes off so this prevents voltage drop from heavy acceleration to trigger the alarm. The Precision Alarm will go off once the desired cutoff is reached. You can see the difference between a normal alarm and the precision alarm by clicking on the video link below.
