Discharging your battery to very low levels can cause irreversible damage, reducing its performance and ability to hold charge. Battery guards prevent this excessive discharge by disconnecting the battery from loads in an under-voltage situation. They also disconnect the battery in an over-voltage situation, so protecting sensitive electronic appliances from damage resulting from faulty alternators or chargers.
There are a number of pre-programmed lower voltage thresholds that can be selected to suit your application and the battery guards automatically detect the battery voltage when connected so can be used with both 12V and 24V DC systems.
