Battery Discharge Indicators

Battery Discharge Indicators

Solar, EV, Golf Cart Battery Indicator, meter, gauge 12, 24, 36 or 48 Volt Rect

Only One LED lights at a time.

Battery Condition Indicator -Solar System, Forklift, Golf Cart or other 12, 24, 36 or 48 volt DC battery powered equipment.

This unit will work on both 12, 24, 36 or 48 volt systems.

For use on any equipment where the battery status is important.  It is specifically designed for battery power equipment to monitor the charge status of the battery or batteries.

Some mechanical aptitude is needed to make the installation. If you are not capable of finding an appropriate voltage supply, you may need to seek the help of a professional for installation.

The only available instructions are provided below.

  • Battery Indicator Status
    • The battery meter has 10 LEDS that will light to show the battery condition. When fully charged, only the 10th LED will light shown a green LED.
    • As the battery discharges, successively lower LEDs will light; the 9th, 8th, 7th and so on lighting only 1 LED.
    • At approximately 30% battery life, the #3 LED will light and the color is Yellow as a caution indicator.
    • At approximately 20% battery life remaining, the #2 LED will light as a Flashing Yellow.
    • When the battery discharges to approximately ~10% remaining life, the #1 LED will start FLASHING RED with the #2 LED FLASHING Yellow alternately.

It is recommended to have the battery or batteries recharged when the #3 LED lights Yellow as a safety margin to prevent dead batteries.

CAUTION: CAUTION: This is not a full proof device and no warranty is made that your battery/batteries is/are in good condition.

Installation Connections

The terminal marked “+” is for positive volts. The terminal marked “-” is for ground. These must be hooked up for the indicator to record battery usage. With only these two terminals hooked up, there will be no display showing. This is done to conserve battery power, but the meter is monitoring the batteries.
When you want to see the display, connect the terminal marked “C” to a positive volt source (+ and – terminals should still be connected).
“C” can be hard wired to have the display showing all of the time or can be used through a momentary contact switch to see the battery status by depressing the momentary contact switch. Another method for installation would be to connect “C” to a terminal coming from a switch key that goes hot when the key is turned on. Remember that + and – must always be connected. 
NOTE: For the meter to be reset to full, it is necessary that the meter sees the charging voltage for as little as 1/2 second. If you have your meter hooked up only from a switched source for both the + and “C” terminal, you must switch this on during the recharge cycle for less than 1 second to reset the meter.
R Terminal – An internal relay logic output allows powering auxiliary devices using your external solid state relay. The relay logic output is present until the battery is “empty” at which time the logic output shuts off.

Round battery indicator with hour meter – ADJUSTABLE

Adjustable Voltage Battery Discharge Indicator
adjbathr

A lot of engineering packaged in a small gauge.

This series of battery gauges are multi-functioning devices … adjustable voltage range, separate controls for turning on the display and hour meter and an internal relay for powering auxiliary devices.

The battery gauge “empty” voltage reading can be adjusted to closely match the gauge to the actual battery level of charge. Seven battery voltage ranges can be selected for for each voltage range; 12, 24, 36 and 48 volt operation. See bottom of listing for range specifics.

The gauge is connected directly to the battery, but no display will show until a separate lead wire is taken to plus volts. The gauge is monitoring the battery all of the time. By having a separate connection to illuminate the display, it stops the battery from discharging if left for extended periods.

Another connection is used to enable the hour meter. Therefore it is possible to view the battery state of charge, but not accumulated hours until it is desired to do so.

An internal relay logic output allows powering auxiliary devices using your external solid state relay. The relay logic output is present until the battery is “empty” at which time the logic output shuts off.

Golf Cart Battery Indicator Meter EZGO Yamaha Club Car 12, 24, 36, 48 VDC

PRO12-48M Battery Indicator

  • Auto Ranging Battery Indicator – Connect to any fully charged lead acid battery system and the meter will select the proper range, for 12, 24, 36 or 48 Volt DC systems.
  • Works on all lead acid batteries as the meter can be set for one of two discharge curves found from different battery manufacturers.
    • Curve 1 – Standard Lead Acid batteries have a discharge curve of 10.4 volts empty to 12.34 volts full (multiply by 2, 3 or 4 to get the range for 24, 36 or 48 volt systems).
    • Cruve 2 – For newer designed “hot” acid batteries with a discharge curve of  11.5 volts empty to 12.7 volts full as found on Exide and Trojan deep cycle batteries  (multiply by 2, 3 or 4 to get the range for 24, 36 or 48 volt systems).
  • Internal Relay – can be wired for Normally Open or Normally closed operation – limited to 200 ma.
    • Relay opens or closes (depending on how you wire it) when the display shows fully discharged – flashing red #1 and yellow #2 LEDs
  • Can be used on forklifts, golf carts, solar sytems and any other battery powered equipment
  • Battery Status
    • The battery meter has 10 LEDS that will light to show the battery condition. When fully charged, only the 10th LED will light shown a green LED.
    • As the battery discharges, successively lower LEDs will light; the 9th, 8th, 7th and so on lighting only 1 LED.
    • At approximately 30% battery life, the #3 LED will light and the color is Yellow as a caution indicator.
    • At approximately 20% battery life remaining, the #2 LED will light as a Flashing Yellow.
    • When the battery discharges to approximately ~10% remaining life, the #1 LED will start FLASHING RED with the #2 LED FLASHING Yellow alternately.

It is recommended to have the battery or batteries recharged when the #3 LED lights Yellow as a safety margin to prevent dead batteries.

CAUTION: This is not a full proof device and no warranty is made that your battery/batteries is/are in good condition.
