What happens to lithium batteries when you get to around 4-5 years of battery age? Does the range also start to drop off? What warning signs does one get with a lithium battery that it needs replacement?

The life expectancy of most Lithium batteries in golf carts, is expected to be 8 -10 years. Given that no one has had one for 8 -10 years yet, I guess that's just an estimate. They could last longer.
Just like your cell phone, the amount of charge available will decrease with age.
Based on my experience, a 105 amp in your golf cart, you'll have about a 15-20 mile range, depending on speed & conditions.
150 amp is about 25-30 miles.
210 amp is about 40-50 miles.
I could probably get 60 out of my 210 amp, but I'd have to really be nursing it, the entire trip ... & hope it was downhill.
As long as your Lithium battery is charged (operational) you'll be getting 100% power from it, but at some point, you won't get power for the same length of time. At least that's how I understand it.
