Prevents dead batteries, Measure voltage tells you when to charge your battery. Allows for maximum discharge, extends battery life by not letting the battery become too discharged. The alarm is a loud high pitched pulsating alarm with flashing red LED indicators.

Lithium Battery life is measured in charge cycles. To obtain maximum battery life the voltage must be maintained within a certain range (see chart. While a lithium battery can be discharged to zero and still recover, if the voltage goes below a certain level the cycle life will be reduced. The charging source should protect the high end. This discharge alarm will indicate when the battery should be charged before the cycle life is diminished. 

Great for batteries on vehicles being stored. Trolling motors in use. Battery banks. Extends the life of your batteries by not letting them get discharged to low.
