I have personally done distance checks on my Precedent, 40+ miles, and my Ezgo RXV, 53+ miles, for a single charge. I built both packs myself. The actual measured useable capacity from 57.5v to 50v. is 90AH for both packs. The only difference is that Club Car is a DC system and the RXV has an AC system which is ~20 more efficient.

I have driven from Orange Blossom to Brownwood (13.2 mi. one way), played 9 holes, drove around a bit sightseeing and then back to Orange Blossom with right at 50% left in the pack.

Due to the linear discharge curve, these batteries will not suffer from "voltage sag" like FLA's. This means with a nearly dead battery you can drive over the bridge at 20 mph from a stand still at the bottom. These batteries should still have nearly the same capacity in 5 years as today due to the low stressing of the cells (never charged over 80% or discharged under 25%, seldom under 50%). I have Zero, 0, zip, none, nada routine maintenance. When I leave I simply charge to 50-80% unplug 2 connectors and walk away, when I return after several months it may have 1/10 of 1 volt loss. I keep a 50' extension cord just in case I ever need to charge with the onboard charger.

I also hear that lithium is dangerous all the time. Ponder this: that awesome new smoke detector that lasts for ten years, has a battery in it that has the same chemistry as most of the "drop in" lithium golf cart batteries.... if it was a fire hazard would they be putting them in smoke detectors... It is much more likely that someone will suffer acid burns from an exploding FLA battery or poisoning from the hydrogen sulfide from charging than a lithium fire. I hear all the time that gas carts are safer... let a spark fall anywhere near a shot glass of gas.... and then there's carbon monoxide and carcinogens.

Typically lithium cells if produced correctly will only become dangerous (a fire hazard) if they are ever (even once) over charged or over discharged. If this ever happens they should be removed from service. Most batteries, but not all have protections built in, so I recommend verifying especially if they're affordable. Over charging or over discharging can cause dendrite growth within the cell (like mini stalagmites) which can pierce the thin membrane that separates the two sides of the cell and cause a fire.
The other common cause of lithium fire is because of manufacturing defects in the membrane (Samsung cells around 7 years ago) or off brand manufactures using cheap materials. Samsung had a hiccup years ago but is a top of the line lithium cell manufacturer.

Don't get me wrong, lithium is not perfect, but don't believe everything you heard from someone who was told a friend or read it on Facebook... because we all know that Villagers are typically current with technology. Lol.

Do your own research and make an informed decision. Get batteries that are only made using quality cells such as Panasonic or Samsung. If they don't disclose what cells are used in their batteries I would keep looking. If a battery company uses quality cells, they will use that as a selling point for informed consumers and typically list it in the specs.

The system that looks most interesting to me is new to market from a company called RoyPow which is a subsidiary of EVE Energy which is a big energy company in China and also produces their own cells. I've been looking at the S51105, which is a 105AH, 16 module, self contained with a BMS and necessary safeties and a 15 amp charger for around $1,850.
