PRO12/24FRC, PRO36FRC and PRO48FRC – ProPower’s 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.

These units will work on  12 and 24, 36 or 48 volt systems depending on unit selected. They are designed for standard lead acid batteries and will not work on all battery types. See below.

Not for use with Trojan, Exide, PowerTron, Interstate, Continental, US Battery, AGM batteries, Walmart batteries and some others. If you have these batteries, they have a different discharge curve than the standard lead acid battery. Order PRO12-48R for 12, 24 and 48 volts systems. Order PRO36FRC-R for 36 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.

We ship  meters within 24 hours of payment or next business day.
