Cart lunges/loses power

[DWesley]

I have a 2011 EZ Go 48volt TXT. Bought it a couple years ago and put a lift on within the first couple months . Anyway, ever since I put the lift on the cart lunges/loses power when the battery starts to get low. It has been continually getting worse as time goes by.

We mainly use it at a camp ground where there are alot of hills and trails. That may be adding to the problem.

What is causing this? Are my batteries junk or is there a cheaper fix?

Thanks for your help!!!

Can anybody say battery time , . How old are batts ?

Lifts are typically done to accommodate taller tires and taller tires reduce the torque where rubber meets road, which may be a contributing factor, but your batteries are also going on 4 years, which is about the typical useable lifespan.

The batteries are the be original batteries.

That's kinda what I was thinking but didn't really want to shell out the cash.

Is there anything that can be done to help with battery life while running a lift?

Thanks for your help!!!

The taller tire essentially increases the rear end gearing. This requires the motor to produce more power to turn the wheels, a situation we call torque loss. For 4 year old batteries this may be the final straw. You can try putting the old smaller tires on and see if the problem stops.

It sounds like battery time.
