The 205ah lithium battery from Evolution has a 5 year full warranty and a life expectancy of 3000 charging cycles. A charging cycle is not every time you plug it in - 1 cycle = 100% charge. If I drive the cart down to 50%, then charge it, that's .5 cycles.

I've got 1,500 miles on my cart in 5 months with 21.5 cycles. If you extrapolate that it equates to 210,000 miles and 58 years.

No where near close to "every few years".

I'm pretty sure I'm going to want a new cart before I need a new battery. Replacement cost for a new battery is currently $3K. If something happens and I need a new battery after the warranty expires, I fully expect the prices on lithium batteries to be significantly less... but I've never kept a vehicle for 5 years anyway.

Getting an Evolution D5 saved me over $10K from buying a Star, EZ-Go or fully loaded Yamaha, and I have more features and a better ride than any of them.

I could replace my battery 3 times and still have saved money.

FYI - My old cart was a Yamaha Drive 2 fully loaded with El Tigre seats.

Did the test with same operating conditions but with tire pressure at 30 PSI.

Got right at 80 watt-hours per mile or 0.67 cents per mile.

Just tire rolling resistance makes a big difference...gas or electric. The ride on the EZGO Elite is quite uncomfortable at that tire pressure.
