Not entirely sure what all of this means (does it serve to explain why the cart only runs for 10-15 minutes and at very low power?), but am eager to learn. If I need to replace batteries is it possible to mix 6 volts with 12 volts to reach 48 (in conjunction with controller upgrade)? Acknowledged. Definitely leaning on doing the rewire just to clean out all of the crap currently in this thing, and also to build familiarity with this skillset. |

I looked up Powertron P2000, and found this: https://www.trojanbatterysales.com/product/11073/ This may not be correct, but I'll assume they are similar to Trojans, since they sell them. Attached is a chart based on Trojan batteries, which are 6.37 volts. |

I guess it depends - if we determine that 4 out of 6 batteries need replacing, this will certainly be an option that I will consider. However, if I can get some additional life out of what I have I may temper the upgrade plans and instead focus on making the changes that would be agnostic to voltage (cables, what else? upgrade controller / etc but wait on motor?). |

SOC is State of Charge, and is on the chart I attached. First, how old are the batteries? If there aren't obvious stickers on them, go to their website and find the code. Many are stamped on one of the posts, sometimes with a number and a letter. Generally, well maintained batteries can last around five years. Some do better, others do worse. Next, what did they settle out to, as far as voltage? Two at 100% and four at 70% seems odd for batteries that are the same age. If you want to try and see how well you can make the week ones, try charging them two at a time with a 12 volt car charger, unless you're lucky enough to have a 6 volt one, like me. No need to disconnect them, unless you can't get two in series. See if you can get the four ones closer to each other, then try several back to back charges with cart charger. Just unplug charger from cart, some chargers may need a minute, then replug, making sure charger starts again. Depending on their age, if it's not a big deal to take all six, a dealer may be able to properly load test them and tell your their condition. Make sure they can test golf cart batteries. They are different than automotive cranking batteries. I did all of my upgrades at once, with the exception of my motor, which wasn't really necessary, but increased speed. To go to 48 volts you'll need charger, controller, solenoid, and likely cables. Do all cables at once. If you need to defer anything, you can dial the controller amps down and upgrade the FNR later, or replace with a reversing contactor. If you didn't find it, here's a well written explanation of what each link in the chain does: https://www.cartsunlimited.net/upgrade-suggestions.html Finally, I reread your first post, and you don't have to worry about any clicking or a twist test when you first turn the key on, as you have a series, not an RXV. You do not need DI water. Distilled, which is different than simply drinking water. Older batteries need watering more frequently, as does operating in warmer weather. Batteries should be charged after each and every use, or at least at the end of the day. I don't see where you ever told us tire size. Larger than stock tires pull more amps, and deplete batteries faster than stock 18" tires. To "load test" them yourself, hills are ideal, but not necessary. Connect your volt meter to each battery one at a time, and note voltage after accelerating to top speed. Repeat for each battery. This is easier if you don't have a trailer to carry cart to dealer, or if they don't have a load tester for golf cart batteries.

Re: I want to learn how to maintain my EZGO (unknown model, battery and power issues)
Awesome feedback! Tires are 23.5" (oversized, lift kit).
I do have a 12v charger. To clarify, I would connect one clamp to the the "in" post of battery A and the other clamp to the "out" post of battery B? All of the ones that were below 6.43 happen to be next to each other in sequence. Regarding testing with volt meter as the cart reaches top speed, I have a basic Klein unit with mechanical (hand) probes - what is the best practice method / addon device to secure the probes to the battery leads without using my hands? Will confirm the rest later today. You are awesome!!! |

Is it possible the previous owner was using two circuits of two batteries - 12 volts - to run his TV and other things? That may account for weaker batteries, if they are the same age. |

There's cheap kits out there too that come with just the wires and alligator clips that snap on to the probes, I found one the other day at dirt cheap.

Re: I want to learn how to maintain my EZGO (unknown model, battery and power issues)
All - I had to table the project apart from grabbing some of the rewiring components. Did just see what looks to be a sweet deal on AGM batteries (6x 6v Leoch DTA6224s for $250 total) but they are used (were pulled out of another cart). Am told that all resting voltages are over 6.3 and that a full refund would be available if I am not satisfied (seller seems reputable) - does this seem worthwhile for short term or should I run far away and refocus on the more expensive, time-consuming but ultimately more rewarding reconfig to 48v?
