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. And I do hold you with the up most respect as a well knowledgeable person with electric golf carts.
