	Superbly Engineered Products, Retail, Wholesale, and Custom Designed! Here is a convenient way to prevent over-discharge damage to batteries in RV, boat, camping, and battery backup systems. It prevents the battery from discharging below a predefined, user adjustable level. The protection circuit also protects against overload and short-circuit conditions, protecting not only the battery, but also any upstream or downstream wiring.

Q: What is the intended application? A: Automatic control over the amount of charge drawn from a battery. This prevents damage to the battery and extends the cycle life. 2. Q: How does the module work? A: A DIP switch is accessible from the outside of the case. It is set to the desired cutoff voltage. The input leads are connected to the battery and the output leads are connected to the load. When the battery voltage is above the setting the green "operation normal" light is on and the battery can supply current to the load. When the voltage of the battery drops below the threshold setting the red "battery low" light comes on and the load is disconnected from the battery. 3. Q: What size wires should I use? A: As big as is reasonable. Our web page http://www.powerstream.com/Wire_Size.htm says that the 6 square mm (between 9AWG and 10AWG) is good for 60 Amps for short runs. For longer runs the wires should be larger, for lower current the wires can be smaller or longer. When using the calculator on our Wire Size page note that the voltage drop only depends on the gauge and the current, not on the input voltage.
