Its just a slightly more complex solution, but it may end up being how i set it up.

1 47ah batt pack in my cart (although I did 14S and not 12S as the Volt comes standard) should run me between 11 and 13 miles range on pavement with no hills where I live.

And the stock 48V controller can handle more V for sure. I don't know longevity but my stock EZGO TXT48 controller handled the full 58.8V (and also one time I accidentally overcharged the pack above 58.8V) just fine. I ran like that 4 weeks IIRC and it was still good when I pulled it out to put an Alltrax in there.

I like the Alltrax because I can program a LV Cutoff as a backup safety precaution. And I can program all kinds of other cool stuff, but the LV Cutoff was what sold me on it.
I was going to use the same charger you have, did the cut off fail in the charger? The only reason i am resisting the controller change is its kind of pandoras box of other changes that go along with an Alltrax change in older carts.

That would be split with six and eight if you are using 14. here is my diagram. You need to confirm it is correct before using, as I'm not making any representation that it is.

The overcharge was from my stock Powerwise charger... I was looking for a charger to use and I bought a shipped-direct-from-china charger. It worked one and a half times... Then I started looking for one I felt I wanted and would last a bit longer and i took a bit too long. In the interim I was using the Powerwise and had it on a timer and would go out and check it occasionally then unplug.

Not a big deal, I could stay on top of it... But one time I forgot and overcharged... That's when I just grabbed the Meanwell and it's worked great for me since. Since the Lith doesn't require frequent charging like Lead Acid I've really only charged it maybe 10+ times with the Meanwell... It's still working fine and I see no issues with it, but I've not used it for 100+ charges...

The Meanwell does have a parasitic drain when unplugged. Not a problem if you physically disconnect it. I set it up as an on-board charger so I put in a disconnect because of that. I'd still recommend the Meanwell. It does get a little warm so I just make sure it has ventilation around it when charging.

As for the Alltrax, I went with the 300 amp (350 amp peak)... I think that's 75 more peak amps than stock, but when you drop 400 lbs of lead and add the controller it makes a big difference. And with the 300, you don't need the heavy solenoid to go with. The most current I've seen on the logs is 304.1 amps of battery current draw once. Most of the time it is far below that and the 304.1 was only a single data point on only one log file. None of the other logs ever reached a full 300 battery amps. I still tell others that the 400 is the way to go, mainly because if I told them 300 and it weren't enough for them I'd feel pretty crappy having directed them the wrong way. For me and my specific cart in my specific situation, the 300 is very much plenty fine... Flat land, 23" tires, 4 people on a cart and rarely pulling heavy loads (like Christmas floats) and the XCT300 makes me plenty happy. Series may be different and aftermarket motors are absolutely different. Your Mileage May Vary.

The modules finally showed after a 2 day delay in Portland. All showed 4.08 per cell. Put together a 7 module pack and went for a test spin. Seems slow but that may just be me, gps said 15 so i guess its not to bad for a stock cart. Gonna check the Vglide sweep and make sure everything is correct. Went for about mile run around the block with a pretty decent hill. Checked all the temps after and the motor, controller, and all the cables where at ambient temp so its not working real hard. Any other things to check or does this sound about right for a stock cart on 18" tires?
