The big savings is using three deep cycle marine for for a little under $300. But there's not much savings when you use six of them at about $600. 6V deep cycle golf cart batteries can be as low as $700. From what you describe I should be able to get along with 3 as you did in your first video. Thank you for these excellent videos.
The theory behind using 6 volt batteries was the amount of plates/AH available because there was only three cells leaving more room for plates instead of dividers for the 3 extra cells. I have no idea if that is still true or if it even was true back in the day.
Can you go a bit more in detail of how you connected the batteries ? You mention series and parallel ? I'm a bit confused on that part. I thought it had to be one or the other. You mention 36 + 36 = 72 Volts SO I'm concerned about burning the motor or controller up. Can you maybe go through the wiring sequence a bit more and also what battery group size and type (number on side of battery) did you use from Walmart ? Thanks, nice video.
Certainly! We will be making 2 banks of 36v in series, then connecting the two 36v banks in parallel. Set up the First Series Connection (Group 1 - Battery A, B and C) Connect the positive terminal of Battery A to the negative terminal of Battery B. Connect the positive terminal of Battery B to the negative terminal of Battery C. This creates a series connection within Group 1, resulting in a total voltage of 36 volts (12V + 12V + 12V). Set up the Second Series Connection (Group 2 - Battery X, Y, Z) Similarly, connect the positive terminal of Battery X to the negative terminal of Battery Y. Connect the positive terminal of Battery Y to the negative terminal of Battery Z. This establishes a series connection within Group 2, also resulting in a total voltage of 36 volts. Connect Both Series Groups in Parallel: To combine the two 36-volt series groups, connect the positive terminal of Group 1 to the positive terminal of Group 2. Connect the negative terminal of Group 1 to the negative terminal of Group 2. Result: By connecting the two 36-volt series groups in parallel, you will get a combined output of 36 volts. This setup correctly creates a 36-volt power source using six 12-volt batteries, with two sets of three batteries in series and the series connections then connected in parallel.
I love this and similarly, I'm trying to get one running for my mother-in-law and she can't spend $1,400. I noticed in the notes that your original charger was fried and the new one looks to have a regular golf cart battery connection, so assuming I could simply leave her existing charging port in place with the newer charger you mentioned. Could you confirm and also, would using her old charger that was used with (6) six volt batteries be a no-no on your application? The only other thing I would ask is if you could send a photo of the final connections. I could clearly see the "neg to pos" "neg to pos" etc. on each battery, but couldn't see where your 12 volt converter was connected or the main power and ground. Awesome video!!
That's sweet. I am putting 3 AGM 125 amp hour batteries in mine and can't use my charger because they say it could ruin the batteries. I'll look into this Summit charger. Thanks!
Hi, glad i found your video. I just had a 1997 ezgo txt freedom and its in bad shape. Had no batteries. All we want to do is ride around our yard. How would a cheap (80.00) 5 amp smart charger from Amazon work? Also does yours still hold a good charge on just 3-12v. 8 months later?
I cannot recommend enough the Summit 2 charger. Mine was used off eBay for $150. The key is you need it to handle the total voltage of the cart (36v/48v) and charge to that rate PLUS it needs to cut off when full. After 8 months our batteries are holding up excellent.
Hey Chris! I did 2 banks of 3 in series (12+12+12 =36) and I put the two series in parallel. I connected the controller directly the batteries. I should be picking up that cart from the farm this week. I plan on doing a few videos on it. In the meantime - I found this photo online that explains the wiring diagram. Hope it helps! 1.bp.blogspot.com/-M1ODn4PU4tg/YJDjFM_DaVI/AAAAAAAAAvc/T8qNwnKsNr4DfsI0VB-YPOHgOSjOxS0YgCLcBGAsYHQ/s710/battery%2Bconnection%2Bin%2Bseries%2Band%2Bparallel.png
@@BootstrapRevival it went great! I have a 1987 36 volt ez go text tron. I picked up 3 of the batteries you had linked, installed them, and the golf cart ran for like 2 hours before I had to charge them again. Zero issues so far. I was worried I would have to pay like 1k to get it running again. Total bill was like $306 for me.
I really appreciate your comments and recommendations for the Lester Summit II charger And how it contributes to long battery life by shutting off the fast charging at the proper time. At what voltage is it shutting off on your 36 volt battery system?
That is a great question that I don't have an answer to. This cart is currently in another state and I just sold my spare summit 2 charger. Bill with support is super responsive via email and could probably provide you an exact answer. (service@lesterelectrical.com). I will say I love these chargers. I've used them on multiple carts in multiple battery configurations and they have been rock solid.
Hi there, it’s me again lol! Do you happen to have a link that you can share of the eBay plug adapter thing that you got? I bought the charger that you recommended. I just don’t want to cut an extra hole for mounting point for the charger. Thanks again looking forward to getting this thing up and running.
I’m with you. No need for extra holes. I used this cover: www.ebay.com/itm/275074255695?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=s-yFbcDGSR-&sssrc=2349624&ssuid=XkkWGqpFQQq&var=&widget_ver=artemis&media=COPY
Hey glad to watch your clip. I am considering going to a similar set up, but I was thinking of using the dlt batteries, the kind that are very big and are used in tractors and road tractors. They usually have 1000 amps/ea. how many amps are you suppling to your cart to get 20 miles(i think thats what you said)? Have you considered this set up with a roof mounted solar panel?
Can you recommend a less expensive charger. I picked up an old cart for my grandkids to ride around on and am looking to go cheap. I plan on putting three 12 volt batteries in it for now.
I would still highly recommend the the Lester Summit 2 but used off eBay. Make sure you read the little white sticker. The 48v ones will drop to 36v. One model will not support a lithium profile but they will all support lead acid batteries. All the ones on Amazon I'd choose over the lester cost more that I've paid for used ones off eBay.
I’m considering doing this. Would you do it again? I seen you did a Lithium one recently. Other than the cost and the distance you gain out of the lithium would you still recommend the 12 V version? Have you had any issues?
Great question. I honestly can't complain about either the lead acid or the lithium. Both have been extremely solid and without issues. I think it come comes down to budget and a good charger to manage the batteries.
Can you connect (2) 12v 100ah to make 12v 200ah then 2 more 12v 100ah to 12v 200ah then the other (2) 12v 100ah to make 12v 200ah then connect all 3 12v 200ah together to make 36v 200ah
It will auto select voltage if you are using lead acid batteries. You can use the app and tell it what type/brand of batteries and voltage - it will auto pick the best for you. Alternatively you can pick your own profile out of their app to load. Support was also extremely helpful and responsive
I used marine dual purpose (starting/deep cycle) batteries. They are rated at 690 MCA which is marine cranking amps. I have no idea how many amp hours they are.

Honestly - I have never played a round of golf. I have zero idea on how far 9 or 18 holes would be. You can always download a gps app on your phone and measure the distance when you are there next. I got 10 miles in my very hilly neighborhood.
@@BootstrapRevivalGoogle maps will allow you to determine distances even before you go there. Using it in satellite view will allow you to pin in your distance points.
Yes, it was for the front LED light bar and backup light. It’s used on the farm often after dark. You could just attach the positive and negative to one 12v battery and work fine - I wanted to load all the batteries evenly.

I've used them on multiple carts. Love those things!
Where can I find these adapter plates?

You've been using it for 8 months or did they only last 8 months?
Thanks for the DIY video, Have you thought about increase the voltage?
If you increased the voltage you'd fry the DC speed controller. Keeping it at 36v has been rock solid!
So if my cart is 48volt I would need 4 12v correct?
That would do it!

The golf cart cruising about 15 mph will be consuming 50 to 70 amps.
So that makes it 50AH to 70AH per hr consumption.
Looking to buy a cart for my sister-in-law. This video will help after purchase. Thanks!
Glad it was helpful!
Good information Tony Stewart....
So my question is if it was originally a 24 V system how do you keep from burning the motor up with 36 V?
Its a 36v cart. It came with 6 6v batteries.

Hi, what amp hour batteries did you use, I am looking at 12v 170ah.
I used marine dual purpose (starting/deep cycle) batteries. They are rated at 690 MCA which is marine cranking amps. I have no idea how many amp hours they are.
What bank do you hook up the positive and negative from the charger?
Straight to the battery bank. I'll see if I can draw up a wiring diagram.
