I've been looking for that info about O'Reilly's cart batteries. Please post a link to it or a picture without anything circled.

There are so many variables that determine how many amps a specific cart draws while it is being driven that the only way to find out how far a cart will go (or how long it'll run) on a single charge is measure it.

If your cart averages less than 75A, then it will run longer than 66 minutes, if it draws more, it will be less.

Also, new batteries only have about 75% of their rated storage capacity until they are broken in, which takes about two dozen charge cycle or more.

In addition, the batteries are rated at 80°F and if they are cooler than that, they will have less storage capacity, which results in less run time.

Like I said, too many variables to make a good guess.

This is for all their batteries so you will need part numbers for the deep cycle batteries. The ones I got are part number EV125.

What is the best way to measure the avg amps my cart gets?

I use the logging function on my Alltrax controller. Set it to continuous mode and log a 'normal' run through the hood. Then look at the various point-in-time measurements to see what's going on.

For my cart it pulls right at 70 amps when cruising at a steady 27 mph. Pulls far more when accelerating. If you don't have a controller that lets you log then I doubt you can measure your amp usage accurately. Unless you have some really fancy equipment laying around.
