1996 EZGO TXT Full Pack Voltage Low

Hello, I have a project cart 1996 EZGO TXT 36v. I've had motor armature repaired, brand new interstate deep cycle 6v batteries installed, all new wire kit between batteries, except main wires going to controller and motor. New solenoid replaced old forward reverse switch with a new toggle switch, so everything has been fixed or replaced besides those cables i previously mentioned and the controller. I started having issues at campground last summer/fall with the pack voltage ,after charging , would only be between 36-37.3volts …. Everything I've read says I should have a pack voltage of 38+ when fully charged. Bought a brand new $300 charger 36v 18amp smart charger by form charge. If after a full night of charging, I unplug the charger and plug it back in and let it run again, I can sometimes achieve 38+ but only after doing that process. I purchased a battery tester and all batteries check out according to that and my voltmeter. What's my next step? Any ideas? I do have some larger tires/ rims on it so I know that slows it down and shortens my run time but starting off the day with only 37 or less volts , I can't go very far. Any help would be much appreciated thanks.

I suspect a weak battery in your pack. Interstate only offers a one year warranty; even trojan only offers 18 months. Your pack voltage is a little low and even good resting voltage does not always mean the batteries are good. My go to method is to load test each battery individually. I usually disconnect them when I do this because it doesn't hurt to clean the terminals while you are at it. I bought a battery tester that tests resting voltage and will also place a load on the battery to see how it reacts. You attach this tester to your battery and immediately gives you resting voltage and then you depress a small switch for 10 seconds which places a100 amp load on the battery . I quickly found a bad battery on my cart this way and have also ruled out bad batteries on my neighbors cart. Here is a link to the tester I bought on Amazon. Best of luck to you

I bought a load tester. All batteries read just over 6v when attached and then needle just slighty moved to “ weak” when put under load. Exactly the same for each battery separately , all unhooked from everything . Im stumped lol
