GEM E2 2001 Cart Charger is Bad. Is Zivan the only option?

My charger supposedly went bad recently but a new replacement is about $1000 plus labor.
72 Volt Charger 10 AMP output 110 Volt Input - ZIVAN
is what it says to replace it with. I have GEL batteries
Can anyone recommend a battery charger that would replace the ZIVAN?
I know that a rebuilt ZIVAN is about $600 on ebay but one says not for use with Gel (Dry) Batteries so I’m confused what to buy since other sellers don’t state information on what their charger’s compatibility is.
I know that ZIVAN would give me the LED colored lights indicating charges and faults.
Will another brand match a ZIVAN for the 2001 GEM?

Delta Q works in all Gems. One from @LithiumGods will drive an led also.
About $400 I believe.

Thank you very much

the Deltaq is also lithium compatible for future upgrades.

@LithiumGods . I have been told that my 2002 GEM will operate with the Delta Q but can connect with ring terminals. What modifications will need to happen to accommodate the ring terminals connections. The car has a Zivan charger 72v.

you hook pos and neg charge wires where the existing Zivan wires go and then hook the 2 small zivan wires(interlock)together
