12 volt and
24 volt Smart Battery Overdischarge Protectors with 60 amps pass through and solid-state control |
|
It is well known that overdischarge is the biggest enemy of lead acid batteries. This device prevents your battery
from being discharged below a pre-defined point. |

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.

Questions and Answers
1. 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.
