I have had multiple golf carts running on Amperetime 12V 100Ah modules (wired 4S for 52V). One cart running the original $420 units for a few years now, and one running the cheaper LiTime (now $230 each shipped off Amazon) at 36V. Both of them get absolutely hammered daily in the wet, mud, dust, shock, vibration, etc.
The batteries are bulletproof for this application and passed all testing including Short Circuit - So ignore the warnings that you cant use them for Golf Cart Applications AFAIAC. If you need LiFePO4 for Solar, Golf Cart, Stationary Storage, etc -> 420% I can vouch for Amperetime / LiTime 12V 100Ah Stackable Units.
Anyway - If you are into Golf Carts, eventually you start finding the failings.
* Steering Rack
* Controllers
* Throttle
* Linkages
* All buttons and copper
* Tires peel off
* Frame welds break
* Every part of them rots, rattles, and degrades
Anyhow

G22 Variants
2001 - 2004.5 : GE Controller mounted low
2004.5 - 2007 : Moric Controller mounted high
In this case we are the G-MAX (JU2) but in Electric (G22E)

There were 3 motors from the factory over the years
Some better some worse - GM was better I believe
Hitachi was weak

There are Series and Shunt wound motors
This one is wound SHUNT
It does Regen, Shunt Motors are referred to as “Regen Motors”

WOUND SHUNT
Controllers changed a lot over the years. Moric were considered to be low reliability. Ours appears to be UNMARKED
We presume we had a 48V 300A controller. Modern replacements are 300A, 400A, 440A, 500A, 600A. 300A would probably be similar but who knows what we had. 400A or 440A would probably satisfy. 500A would invite possible trouble and drive upgrade in the contactor and wiring… possibly stressing out the batteries. NOTE that is MOTOR current and not BATTERY current which can be quite different.
---------------- CONTROLLER
G19 and G22 controllers are different but SHOULD BE compatible. We have a G19 controller in unknown condition. I may pull it and give it a try. G19 is more traditional extrusion, side plug, made by GE, probably repairable. G22 is forward facing, front plug like Sevcon, probably Moric.
Close Guesses and Keywords: JU2-H6510-21, fx302g027, XCT-48300-YDRE
Likely Match: XCT - 500 - G22 (significant torque upgrade…)
Vintages of controllers
48V G19 - GE Controller mounted low in front battery compartment
48V G22 - Moric Controller mounted high behind seat
Drive G29
$820 Likely to be exact stock replacement (Assuming nobody tuned ours)
Dont even think about it. Pay more for less? Bah.

I am going to try to pull and swap the G19 controller and put that in the G22. It may underperform or give us trouble but we will see.
