Battery Discharge Indicator - 12v To 72v System Compatibility | Solid State Bdi With Open Circuit & Battery Charging Resets, Led Voltage Display

These Battery Discharge Indicator is an inexpensive, easy to install Battery Discharge Indicator (BDI). It is completely solid state and provides a reliable, accurate, and easy to read display of battery state-of-charge.
APPLICATION
This battery discharge indicator is ideal for golf cars, hunting buggies, commercial leaning equipment, mobility aids, electric bicycles, and similar equipment.

RESET METHODS
a c Open Circuit Reset (OCR).
Upon reconnection of a battery, the BDI will reset to the full status if it measA ures 2.09 volts/cell or higher.
a c Battery Charging Reset (BCR)
During charging, the BDI will light LED bar by bar according to the increased battery capacity, the BDI will reset to the full state when the BDI measA ures the voltage of per cell up to 2.35 volts or higher.
OPTIONS
Pin 3 is the collector of a triode without high drive ability. Pin 3 will output a pulse (Note.1) voltage at 80% discharge of battery. It can be used to signal another component or to allow for the disabling of a specified vehicle function, insuring against abusive deep discharge conditions.
(Note.1: Output Saturation Voltage: 300 mV (Type) @ 10 mA; Maximum VCE is 40V; Frequency is 1Hz.)
