36 Volt Club Car Golf Cart Lacks Power

Here's what I've got a 86 Club Car golf cart 36 volt with 3 year old batteries.
It's my first golf cart and first electric. I've had it for a couple of months. Most of the time I spent working on it. I have no plans of going off road and using it where I shouldn't, but I would like to take it up and down the hills on the road and through the pasture. The back seat weighs a lot, but I didn't think it would hurt the performance that much.

It's having a real hard time with hills. Even on the paved road or gravel roads in the pasture it lacks power. Is it the big tires? Could it be the brushes? I haven't gone through them yet. The battery connections look tight, but I'm going through them again.

That should be a 5 solenoid resistor cart. Are all the micros clicking and all soleniods working? Kind of the nature of the beast, my 90 was real slow on 36 with the big tires, lose a lot of low end torque. I swiched to 48 but hills still bog it down some, I think a bigger motor is the only to get rid of that. You do get more top end with the big tires though.

Crap. That's what I feared. Bigger motor costs $$$$.

But the way it is now, I need a full charge to do anything in the pasture.

It's a good setup for a campground, but not good enough for pastures.
 
You could add 2 more 6 volters in the bagwell or any 12 volt to test it on 48 and see if it helps. It will get some of your low end torque back. Worked for me.
 
From what has been said (no torque and having to charge the batteries to do anything) I am thinking that one or, perhaps, all your batteries need to be replaced. If nothing else, an electric with good batteries has lots of torque.
 
Not on hills.Stock electrics slow down on fairly steep hills. On those long grades you really notice.
 
Rereading this post, you say you need full charge to do anything in the pasture. Just for grins i would load test those batt. and check them out with a hydrometer. Ole Copb might be right.

Good looking cart by the way.
 
Take individual voltage readings on the batteries after a full charge and again after a hour or so of run time. The big tires will take away some torque and from what your saying you may have battery problems that will kill your hill climbing. Are any of the cables getting hot after a ride?
 
Yeah, I need to "borrow" the load tester from dad.

I gave it a very long charge and was satisfied with it's performance.
