New Golf Cart Batteries, Trojan Lead Acid or Upgrade to Lithium?

In my experience with carts retrofitted with lithium cells are something to be avoided. However, my experience with them and talking to the manager at the course that used them was a couple years ago, so I imagine things have improved. The problem wasn't with the batteries themselves, it was always the electronics messing up. Additionally, one of the benefits of lead acid batteries is actually their weight. 4 or 6 deep cycle batteries keeps the center of gravity low on carts and makes it hard to tip them unlike gas and lithium carts but that is more of a concern for rental fleets and not personal carts. My other thing with lithium retrofit carts is that they always seem sluggish but that is probably tied to the electronics protecting the batteries. Lithium carts are the future but I'm not a fan of the retrofitting old carts. If you want cheaper batteries and can install them yourself, I would recommend calling your local battery distributors and avoid the golf cart shops. It seems you can usually find the Trojans for under $100/battery. In my experience, Trojans seem to last the longest but there are cheaper options. I've used the Interstate deep cycle in the past and they lasted about 40% less than the Trojans, so the savings wasn't worth it.

I decided to take the jump to Allied Lithium 48V 30AH in my Yamaha G29 in January 2021.  My cart is mostly used for pleasure along 100+ miles of paved cart paths.  My cart is is very good condition for its age, so it will be many years before I need a new one.  I was tired of dealing with the lead acid maintenance challenges and the inconsistent power they provided.  I spoke to a couple different shops.  The first guy said, there was no way he would install the 2 battery unit in my cart. I would not be happy with the mileage and would experience power failure on inclines.  He said a 3 battery setup would be the least he would install if I wanted them.  The second shop I spoke to said, try the 2 battery install, and I could always add more batteries if needed.  I went with the second guy, but shortly after added a third and then a 4th battery.

I must say. the cart runs much better now.  Smoother acceleration, consistent power and speed, 50-60 miles between charges on a much lighter cart.  The cart has a stock controller and motor, so its not much for speed, which I would like to change.  Top end is about  14mph and I'd like to get it around 20-22 mph.  Trying to understand my options for improving top end while minimizing the loss of torque needed for extra passengers. 

Any suggestions?

I'm not an expert, but always thought there was a governor on carts. We have an EZ Go RXV that had some motor work done about 3 yrs ago and it zooms by the other carts. now. I'm thinking they disconnected the governor or forgot to reconnect it. There are a number of dedicated golf cart forums that can give you specific advice.

I took the plunge with my old cart this week.  Ordered a 2 battery setup from Allied for the 36v EZGO txt.  Took out the 6 lead acid batteries and put in two 36v 36ah Allied's.  So far all my electronics work and the cart runs about 2mph faster than before.  My course opens this coming Sat so that will be the real test.  If I can get in 36 holes on a charge and still make it home I'll be happy.  I've got 2 years to be able to add an additional battery if I want more range.  Got the batteries and a charger for $1950 shipped with no tax.

I have a Yamaha Drive2 PTV golf cart with Yamaha’s AC motor, and it came new with six 8-volt lead acid batteries.  The cart gets used an average of three times per week on one of our two golf courses, both of which have sizeable elevation changes throughout the courses.  After three and one-half years the original Trojan T-875 batteries were failing and barely able to make it through one round.  Based on my research, I decided to go with RELi3ON® InSight lithium batteries, provided at cost by RELi3ON®.

While most applications will work fine with just 2 of the InSight lithiums (each is 48 volts, 30 amp-hrs), because of the frequency we use our cart and the elevation changes, I went with 4 InSights for a total of 120 amp-hrs.

After my first couple month’s use of the RELi3ON® InSight lithium batteries, I have found that they perform perfectly.  No matter how hard the cart is pushed, they never even get warm to the touch.  They charge back to 100% and 120-amp hours in just a few hours.  Even after driving around and playing 36 holes on my very hilly courses, the remaining charge is still in the mid 60% range.

Handling and “zippiness” are superb due to the permanent weight reduction.  Another bonus is not ever having to think about checking and adding distilled water to the batteries.

The install was straight forward.  I have done a write-up with pictures if you are interested.  It is at https://insight.daumphotography.com/2021/04/26/36-holes-no-problem-powered-to-go-and-go-with-reli3on-insight-lithium-batteries/

Let me know if you have any questions.

I ran into the issue Captgriff mentioned. I would recommend replacing them with the same type the original cart came with (doesn't have to be same brand) 

More than likely, newer carts are going to be equipped with newer batter types like lithium. 

For reference, I found this article pretty useful.

This is an update on my post above on April 27th, re converting my Yamaha Drive2 PTV to run on RELi3ON® InSight lithium batteries.  Recently I was away on an extended trip and shoot so my cart sat for more than 7 weeks.  I don't like leaving the golf cart on a charger when I am away, so I set it to "Tow" and powered down the lithium batteries.  When I returned and turned the cart back on, the batteries were at 99% of a full charge!  Pretty outstanding.  Never could do that with lead acid batteries in the cart.

Reply to EzgoOwnerx2. Absolutely agree Allied are a joke and should be avoided at all costs. They continually lie about delivery dates and when I cancelled, they told me I couldn’t. I have told them to f... off and they haven’t responded. Aid they do I am filing an FTC complaint and also contacting the FBI as I believe they are just scam artists. Beware.

My update on the Allied batteries.  Used them for an entire season and am very pleased with the performance.  I still have the 2 battery setup.  I can get in 27 no problem.  I think 36 would be pushing it, but I could always add a 3rd battery and get more range.  

For price, ease of install and zero issues I would have no problem recommending them.  I have 2 other buddies that have since gotten them last season and 2 more that are switching this season.  

Here's the only 2 issues we have seen between the 3 carts that have them installed already.  One of my buddies has a lifted and sped up EZGO RXV.  He had to go with a 3 battery setup right away because his cart would cut out when going full speed (around 30mph)  Adding the 3rd battery solved his problem.

The last issue is going to be with any lithium setup vs lead acid.  There is no "run down" period.  With lead acid as the batteries get close to empty the cart will slow down and you can often limp home.  With lithium batteries your cart will go full speed until it dies and then IT WILL NOT MOVE!  We had one night we had to haul a generator out to the course and charge a cart long enough to get it home.  (FWIW that's about 2 beers worth of time)  So just a heads up to keep an eye on your battery meter if you make the switch.

LITHIUM. Before getting into golf the manufacturing company I was with dealt with numerous battery products, mostly lead-acid. When LI batteries appeared, every product increased it's performance.

I have a 6 year old Yamaha that needed battery replacement in June 2021 and i went with lithium.They had to put in a new bracket but it has worked well.

Yes, it requires a new charger but I get at least three rounds on a charge and there is no maintenance. Glad we made the change.

After your conversion is complete your new lithium will batteries offer several advantages over lead-acid batteries:

● They are much lighter weight, offering a quick and smooth ride.

● They offer a no-maintenance solution.

● Lithium batteries charge much faster than lead-acid.

● They retain charge far longer

● They have up to 10 times more battery life

● A Direct drop-in replacement
