Low Battery Cut off and Overload Protection Circuit

Posted on Feb 6, 2014

The battery voltage has to pass through R1 before reaching the load at the output and therefore the current passing through it is proportionately transformed into voltage across it. When the battery voltage falls beyond a certain low voltage threshold, the base current of T2 becomes sufficiently low such that its no longer able to hold the relay i
