I have 2006 Ezra, five of the six batteries are seven years old, one just died, so used your video the convert to three 12 volts from Sam’s, $87/ea. my cart is now 2-3 hundred pound lighter, it runs great. Thanks

Sure it will work, those are group size 27 deep cycle batteries w/ about 75 amps each. Set up in series to make 36 volts, the amps stay the same. 6V golf batteries GC2 standard size are on the low end 180amp (super cheap Costco version) to over 230amp on the really good Deka or Trojan battery. You can also get 245amp batteries in the same size that are used in floor scrubber machines. Bottom line is - yes a deep cycle 12 volt battery will work, BUT 6 - 6 volt golf cart batteries will easily give 2 to 3 times (maybe more) the run time over 3 - 12 volt deep cycle. Compare the cell size between the 12v and 6v - the golf battery cells are 2 times larger and able to provide huge power to get a 1500 to 2000 pound cart (two men, clubs, etc) up and down and around 18 holes without issue, most golf carts run 2 rounds per day so the power is substantial. So if you are just goofing around your neighborhood on a relatively flat surface, you might be ok. But if you are playing golf or hauling something or driving more than a couple of miles you really need the higher capacity of 6 volt GC batteries.

Great video and you are correct it's a much cheaper way to get by - driving slower actually does not help as the throttle is always full speed full amperage draw however at low speed some or most of the current is shunted through a resister bank and is simply wasted as heat at full speed all the current goes to the motor.

Depending on your usage needs this is a good way to save money. You do get less range, I did a swap to 4 12v marine batteries on my 48v cart 5 years ago, still running strong. I use it around the farm about 5 miles a day max 3-4 days a week, so it's fine for me. I get around 14 miles of range at a 50 percent max depth of discharge, compared to 35 miles from the trojan 170 amp 8v cart batteries at a 60 percent max depth of discharge. I recommend bypassing the carts obc and getting a smart charger with a good onboard lead acid charging profile and checking the electrolyte level frequently.

I haven't finished watching your video yet but had to stop and say thanks for clearly explaining the series wiring set up. Just bought an old cart I plan on Restoring but before I do I'm gonna go out to my camper van and fix the wiring set up that's been wrong for 10 years. Iyiyiyiy

I have an old beater 1982 EZ-Go and converted it to "Just" 3 - 12 Volt Marine Batteries...You had 6 - 12V marines in your cart. My old beater would only get around 3 miles to a charge though...my hills are much steeper and are mostly "pasture", although there's a gravel road I run each night too. I've had it 2 years now and it suddenly quit on me...dead in the water at the moment trying ti figure out what's up. I tested the batteries and they are still fine...I use a smart charger that stops when it reaches a full charge. I "suspect" a solenoid issue but have no experience there...I'll keep perusing you tubers and see if I can find clues. (Like your Aunt, I too am up there in age and just need it to do chore and small hauling jobs on the place here) Enjoyed your experiment though - thank you!

Great video that will help many people who may not know/understand the basics of batteries in golf carts and low speed electric vehicles. A couple of additional things, for those who may not be familiar with lead acid batteries (golf cart, deep cycle, or general use). 1) NEVER run them below 50% SOC (State Of Charge) or "half full" on your battery meter. Repeatedly doing this will internally damage the batteries. 2) If you have batteries that have the maintenance caps, get a watering system, like the one that Bootstrap Revival removed from the old batteries. This makes maintenance easier, but you still need to periodically take the caps off and verify the acid level in each cell is correct. IF/When you need to add to them, use DISTILLED WATER ONLY. 3) Extreme heat or cold will kill a battery (ANY battery chemistry). If you live in a climate that freezes in the winter, remove the batteries and store inside a garage or heated shed, where they won't be damaged. Same for if you live in an area that gets extremely hot. Do not store your cart/batteries in a giant oven (metal building, storage container, etc.) where the temps can get 120+. 4) When the cart isn't going to be used for a period of time (longer than a week), disconnect the main leads (Positive and Negative) or turn the Master Switch off, if the cart has one. Option 2 would be to connect a smart charger, and a timer system to turn the charger on for 6-8 hours every week. This will ensure the batteries maintain a proper charge and don't discharge below 50% and shorten the life. 5) Many people cringe at the cost of replacing batteries, and if one is bad, they want to just replace that one. Don't cave to the temptation. Replace all of the batteries, so that they all have the same number of charge cycles, come from the same batch, and should have approx. the same lifespan. Adding one new battery is going to drag it down quickly, as it tries to make up for the weakness of the rest of the "team."

awesome sir. i will be trying this

Hi Russel, hope all well from you. My pleaure to see this video, may i suggest you to experience 48v30ah LFP in GC2 size in your cars? Max support 10 connections parallel

never seen final wire hookups!!! did i miss something

I tried the 3 DC24 battery route. While it worked fine I wasnt happy with the performance once I added larger tires. Ended up with 6 new crown batteries, $680 out the door.

I used these same batteries in my 48V club car with the stock charger. at first they were great, but ended up only lasting 20 months which works out to $200/yr... upgrading to lifepo4 batteries this time.

We put 3 4d30 batteries on our golf cart at work, they are the length of 2 of those batteries so we removed the center divide.

So if I put 3x 12v 100Ah batteries, would my factory charger be able to charge it? My factory charger plug is stamped 50A 600V

Nice video

Great video what app did you use for a speedometer in the odometer

Can I still use my cart charger when I do this???

I want to do the same thing as you in this video, but have all 6 12v batteries hooked up at the same time and only use 36v

I tried this and I dont know if the charger dosent work correctly, but I get less than an hour run.

These 24DC batteries at Walmart are being discontinued. They’ve changed the name to 24M. Make sure you get these deep cycle version which is specified on the label. There’s also 24M that’s not deep cycle. Also don’t get them mixed up with the 24MS.

I understand why one would use three $90 12V batteries in place of six 6V batteries. This gets one around okay for modest usage at a little less than half the price of six 6V. But why use six 12V of these marine batteries when the total cost is just a little less than six genuine 6V deep cycle batteries that will likely last longer due to the full deep cycle design. Marine batteries are a compromise between a starting battery and a deep cycle battery. Here in Central Florida 6V deep cycle batteries are $100 each and up.

My dad gave be an old gf cart with very old batteries. My sister and i would go for rides. The batteries lasted so long that wed drive to 2 other towns (not in the same day). Wed have lunch.. drive around and then go home. 1 town was 6 miles there 6 back. I didnt know i was making the batteries get hot. I did it for 3 years. I ended up having to call for someone with a trailer to come and get me. I burnt the posts right out of the batteries. What a shame...such wonderful rides we had. So now its sat for a year. Im trying to decide what batteries to use. I thought maybe lithiumbut then i have to change other stuff. Maybe the car batteries would be best and dont go driving the country side... What do you all think? Im a 63 yr old female and i can do things like hook up new cables .. Whitch i did so i cobbled them fur a while when i first got it so i could drive it. What do you smart guys think?

Nice range test! It looks like you are short circuiting 3 terminals with the metal plate in the middle holding the batteries in palce. battery 4 negative, 5 possitive & 6 negative. Even if ther is a small margin between the plate and terminals you should consider waht happens when ther is a bump in the reoad and over time displacments of the batteries.

I bought 3 of the 24 dc batteries and a htrc 36/48 volt charger, I’m trying to find out what my low voltage number should be so I don’t run them too low, thanks for any input, it’s a 36 volt ez go

I changed out my six 6v batteries for Walmart's EveryStart 12v Deep Cycle and within six months I can't drive the cart around the house and back before it goes dead. Also, be careful when hooking up your batteries to the cables from one battery to the next. Make sure the connections are very tight otherwise you'll burn up your battery posts (speaking from experience). If possible, double-nut the cables to the posts to ensure they're on tight and won't come loose.

I have that exact cart wanting to convert it to 3 12s

So it say three batteries but it’s six in there?

What MCA Deep cycle Wal-Mart batteries dud you use ! Is it possible to get a picture of the label on the side of one of your batteries ? Great job and info. Thanks ! Love to have picture of the label......

I call these Neverstarts !!!

I’m seriously considering this. I have a 2007 club car presedent. I don’t wanna pay 1200 for 4 batteries. But I want to be able to play a few rounds of golf before they need recharging. Thoughts?

i bought a house on 6 acres of land and it has 2 pole barns and in one of the barns i have this exact golf cart i'm going to change out the batteries and see if it runs

Quick question when you got the battery’s from Walmart did you take 3 of your old batteries so they don’t charge you a core fee?

Can I use 2 everstart 24DC’s and 1 everstart 24MS? Both are Marine batts.

What about those lithium ion golf cart packs. How far do those go. Are they worth the high price tag?

Can you use the charger that is made for golf cart. To charge all 3 at once. Thanks. Great job🎉

were you able to use a regular charger for the golf cart to charge 12 volt batteries

Did you use the same charger to charge the new batteries?

I installed 3 group 31's on my ezgo shuttle and I drive through my neighborhood 2 to 3 times a day plus the kid driving and it lasts me just fine for what I do

Are you still able to retain the stock 36v charger?

Thank you for the video.I have been kicking around the idea of converting my 36 volt to 3 batteries. My main question is with the charger .I have 2 different chargers. The one that came with cart with no monitor and my second on is the little trickle charger with smart cut off only 5 amps. Could I get away with that?

Was the regular charger able to charge the 6 12v batteries? If not, what did you use specifically? I'm new to batteries and don't know much. 🙂

I need help. 36V 2007 EZGO. The batteries are fine. I rode it up the hill with a lot of resistance. The batteries got hot. I went for a hike, came back and the cart wouldn't move. I hear the click when I engage the pedal. Please help.

Must the batteries be Deep-Cycle to work in the carts?

What battery profile are you using on your Lester summit 2?

I tried this, installed just how your video said.. and when I turn the key on and press the accelerator, I hear the solenoid but it doesn’t move. Suggestion?

ok so you have 2 banks of 36v batteries. you said you ran each bank in series then paralled the banks. Am I right so far?....lets say i am...so now you still have 36v but twice the amps/capacity....how far did you go this way and why do this?......I should mention that i did the same thing but only have 3 batteries

I have #3 =12v but all I am getting 33 volt not 36v do I need 1 more battery? or is 33volt ok

So basically 6 12v and every 2 are in parallel making 12v bank with double amp hours, then put 3 12v banks in series so u get 36 volts total with all six and double the amp hours?

Where do you get all of the cables

We just did this and now it wont go. We heard a pop sound when connecting the battery. Do you think we blew the solenoid?

Any update on the six batteries?

Did u need the converter

I am about to get a cart that needs new batteries. I want to do that on the cheap too. Is there anywhere I can look up a diagram of how to wire these? I’m afraid of electricity and don’t want to fry it!

Why two banks of batteries?

LEAD is a terrible pollution. We tool lead out of paint and gas why use heavy , short life lead acid batteries Compare how long they last. Lead is about 1 year life. Lithium are 8 to 10 years.

I’m confused by this whole video. He says he used 3 12v to make 36v which makes sense, but then shows another bank of 3 12v ( behind the 36v bank) which was not connected and seemingly served no purpose . What was purpose for this test? Was the cart tested with the extra weight ? Was it tested with the second bank of batteries behind the 36 v bank in front?

Do the math watt, amp & voltage. And how many times can you recharge it and charger make compatible with batteries. Hey just going to buy a new set of 6 volt batteries Costco. Time on the internet.

Why you run on three batteries if they are six.

How are they doing I just pick up a golf car and batteries look dead

I think your math is wrong on your amp hours … if they are in series you increase the voltage your amp hours stays the same, so for each 36v bank you only have 100ah, so 200ah total as you have configured there…. If you had all 6 in parallel you would have 12v 600ah

It'll be OK for a little while then you'll lose charge quickly theoretically you're running less voltage but the same Amp hour 6 6 volt High output deep cell or lithium will be your best bet wired in series your voltage will be higher along with Amp hours and run time will be 3 to 8X longer especially with lithium perhaps 10X longer but you're talking $1000 to $2000
