Lenny--

I think that no one is responding because no one has an answer to your question.

My two cents is that I would not want to re-battery an old golf cart because the cost of the lithium batteries is so much that you really need new technology in the rest of the cart. The motor, for example, is probably not optimized to the new batteries. Old DC motors probably don't perform as well as newer AC type motors.

Default Lithium batteries

My problem is when lithium batteries go dead there is no warning they just die

It is just simple math but you need to know the power draw of your cart.

The latest EZGO RXV AC electric does about 2.0ah per mile. It does this with lower power output that makes it as slow as a gas cart. The less efficient AC carts are maybe 2.5ah per mile.

4 Trojan Trillium 12V lithiums are 4x110ah=48V110ah or about 110ah/2.0ah=55 miles at 80F.

Note how many electric cars you see at the side of the road because you just never know when the batteries will die - LOL

A 200 amp battery pack would be good for about 70 miles.
A friend of mine build a lithium cart about 10 years ago with cheap china batteries and it would do 50 miles it a cart call a Big Man EV. This was a very heavy ugly looking cart.
With the improvements today, Id say 50 miles would be easy.

First thing you need to understand is that a golf cart does not care what source the electricity comes from as long as its within the acceptable voltage range for your system components and can provide sufficient amperage.

Lithium cleaner, requires almost no maintenance and is safer than FLA batteries provided 3 simple rules are followed, they are never allowed to be overcharged, undercharged or stored over 130 degrees. To do this a Battery Management System (BMS) MUST be used to monitor each cell of the battery pack individually and the BMS must be capable of disconnecting the battery if any cell is over/under voltage.

There are a number of companies on Ebay and the internet that advertise "plug and play" lithium battery replacements that don't have a BMS that will disconnect the battery pack if over/under voltage. Do your research.

I have done quite a bit of research into lithium conversions and have built two 120AH lithium battery packs out of Nissan Leaf modules. I am currently using only 100AH of the capacity. I converted over a 06 Club Car Precedent (DC motor) and a 16 Ezgo RXV (AC motor). The Precedent gets conservatively 40-43 miles and the RXV gets 50-55.

In a 48v cart a 60AH battery pack will get you approximately 20-25 miles and a 120AH pack will get around 40-50 miles.

Orange Blossom to Brownwood and back with a comfortable amount of reserve is not a problem using only 100AH.
