Wear protective clothing and wash your skin afterwards. Battery corrosion and fluid are both acidic and poisonous. Designed to keep track of the level of charge in your batteries. Dirty battery contacts must be cleaned to maintain good battery performance. If your jewelry touches a live wire you will become part of the circuit. Remove all metal jewelry and watches before working on the cart's electrical system.
If the voltage drops below this value, remember to charge the batteries. The battery meter should show the voltage you calculated in Step 1. LED meters need a switch so the lights don't stay on when the motor is switched off. TipsĪnalog meters can stay on all the time because they do not draw any power from the battery. If you use an LED meter, connect the third pin to the switched side of the On/Off switch on the cart dashboard. Make sure you preserve the correct polarity, as LED lights will not work if the wires are the wrong way round. Analogue meters have just two pins, positive and negative.Īttach cable connectors to the ends of the positive and negative wires from the battery, then connect them to the appropriate pins on the meter. LED meters have three pins at the back, labeled positive, negative and switch. Two common types of golf cart voltmeter are available rectangular LED meters and circular analog meters. I'm not sure where the parallel thing came from but I have never seen 48 or 115 volt batteries to connect in parallel.Mount the meter somewhere secure and visible when you use the cart. This is why I asked for results to be posted so I could look at the data, for additional testingĪlso a 45% drop up a steep hill would put a 50.0 volt pack at around 27.0 volts and very close to the cutoff voltage of a stock controller.Ī stock cart IQ model is only allowing 117 amps output not sure that would load the batteries anywhere near that type of voltage drop again I have not seen anything less than 43 - 42 and the batteries still be in good shape.
This would indicate a not so strong battery at least not up to pack standards. Most people do not have a huge hill to test on so I'm thinking a hill that will load the batteriesĪs far as voltage drop I'm speaking from testing again just enough to load the cartĪnd I also said if it drops below a level then check each battery one at a time and look for one to fall lower than the rest. And I know of no one to this day that is running a parallel battery pack. In drag racing golf carts they have always said that a parallel battery pack is the way to go.

If I'm out of line please fill free to set me straight or teach me something about batteries. That's why I told him to wait a hour before he gave us his readings. But your static voltage as I know it is just surface charge as it comes off the charger. Your talking 2/0 welding cables vs a small volt meter.Īnd as far as static voltage being useless. I believe the only way to truly test a battery is with a hand held load tester. Even with a strong set of batteries & a stock golf cart. Of course it is possible & more than likely he will see a 45% voltage drop going up a step hill. I have pop the caps plum off some of the best batteries that money can buy. With just a set of contactors no controller to launch my drag cart I have seen my batters fall well below 45%.
The seconded thing you learn is no matter which type of battery you have you will always have a voltage drop or sage under power. The first thing you learn is how not to abuse your batteries. I have spent literally thousands of dollars in lead acid, AGM's, & Ion lithium Batteries for my drag cart since 2005. I push over 156 volts into basically a stock golf cart motor. You know I have a 1/8 mile drag golf cart. Unless I'm misunderstanding you I have to disagree with your up hill load test. Electric EZGOElectric EZ GO Marathon, Medalist, TXT and RXV. And I do hold you with the up most respect as a well knowledgeable person with electric golf carts. Buggies Gone Wild Golf Cart Forum Golf Cart Repair and Troubleshooting.
