Discharging your battery to very low levels can irreversibly degrade its performance and reduce its lifespan by weakening its ability to hold charge and reducing the no. of charge/discharge cycles available. This 10A Samlex battery guard prevents over-discharge by cutting the power to to the appliances once the voltage drops to a user-selectable level, so preventing further discharging of the battery. It also cuts power once the voltage rises to a certain pre-set level to protect appliances connected to your battery from potential damage caused by an over-voltage situation (e.g. faulty alternator or charger).

There are a number of pre-programmed low voltage thresholds that can be selected to suit your application and the battery guard will then automatically cut power at that threshold to preserve the life of your battery. It automatically detects the battery voltage (12 or 24V dc) and has very low voltage drop and standby current draw.


  • Extends battery life and prevents damage
  • Guards against excessive discharge and over-voltage by disconnecting battery
  • Auto-detects battery voltage (12/24V)
  • 10 programmable voltage thresholds
  • Low current consumption
  • Low voltage drop

It is recommended that the battery guard be installed in between the battery and a fuse/distribution box, as close as possible to the battery.

Suitable for batteries used in caravans, motorhomes, campervans, boats, off-road, industrial and commercial vehicles with a current draw from the battery up to 10A max.

Works well, easy to connect up. Instructions are detailed but default setting works so didn't need to read afterall.
