INTRODUCTION
It is important that most rechargeable batteries are not discharged lower than a specified cell voltage. This is especially true of Lithium Ion (LiIon) batteries which may be damaged by too-lower cell voltage.
This article describes a simple circuit, shown below, that can be adjusted to suit most cut off voltages. The circuit also has an hysteresis which caters for battery rebound and prevents the circuit from...
