This conversion has become a lot more appealing with the 12 volt lithium batteries now out. Six 8 volt batteries give roughly 170 amp hours at 48v, but only 85 amp hours are usable at the recommended 50 percent depth of discharge for deep cycle batteries. They have a lifespan of 1000-1200 cycles or 5-8 years. Six 8 volt high quality deep cycle batteries will set you back about $850-$1100. 12 volt 60 amp hour lithium batteries can be found for $130 each, $520 for four, half the cost of the 8 volts. You get 54 usable amp hours at the recommended 10 percent depth of discharge, roughly 65 percent range of the 8 volt batteries. They have a lifespan of 3000 cycles, or 15-20 years, almost triple the lifespan of the 8 volt batteries.
@@glenntower3590 Amazon has many of them. I have read that the Curtis controllers are prone to failure with Lifep04 batteries. That is an expensive part to replace.
How are they holding up? In the market for new 12volt batteries but like you said you can save a lot by just buying marine batteries. Please let me know!
This setup will work. BUT not for long. Marine batteries cannot tolerate the heat generated by the charger. After multiple charges, they will lose range. A buddy just did this and can't even get 27 holes in on the golf course. His cart used to play 54 holes. Lithium is the only way to go but you will HAVE to purchase a lithium charger. The factory charger will not work and damage your lithium batteries.
I need to ask you something somebody one of my neighbors and keeps messing with my golf cart and changing the batteries and the cords around and all that stuff so the last time we did it I don't know what's going on with it but the lights are coming on but it won't charge and it won't show it charging so when putting the battery connection charger cable on you put that underneath the cable connecting the battery or on top?
It would probably be best to ask a golf cart service person for help, your question is lacking in details and specifics. Don't want to catch the thing on fire or hurt yourself !
I use my same charger, it works just fine, and by the way, our cart still runs great with these new batteries (they are maintenance free batteries also), as long as I remember to keep it on the charger when not using it ! We ran out of power on a run thru the neighborhood and my wife was livid !!! Made it back home just fine with help from some neighbors.
that was the #1 reason to change out the dead batteries . . . I was skeptical at first but after almost a year I am satisfied with my choice @@SmokeyA55
doing just fine, keep them on the charger when not running around the neighborhood . . . we take the cart out and drive maybe 1-2 miles (two - three times a week) give or take and the voltage only drops from 53 to 49-50 after that run. I'm happy with the exchange, all variables of course are different from driver to driver, we don't speed around either, just cruise about.
actually, in my neighborhood we cruise around for up to two miles and still have a good charge, around 53v start to 49v finish . . . works for us, maybe a golf course run, but not sure as I don't golf
@@designandbuildguy I just bought 4 marine batteries and just driving up the street a couple times and moving it around drained it to 50 percent..might take them back and go with real deep cycle.
Never heard of six 8 VDC batteries. Are you sure you counted correctly? Also if they were 8 VDC batteries, what combination of batteries supplied 12 VDC devices like headlights? Finally, I don’t think I would admit that I didn’t check the voltage going to 12 VDC systems before living them. Makes the observe question anything you did.
Yes I counted right, started with the 6 - 8 volt (48 volt total) batteries and I then converted it to 4 - 12 volt (48 volt total) and it works like a champ. The lights are 8 volt bulbs which run off of one of the batteries only. Any added questions are welcomed !
after the fact that you have replaced the batteries, it would be best to check all of your connections as well as where the charger plugs into the cart. I had to replace my inlet charger port on the cart as it was not making a good connection, which baffled me because I never did anything there to upset the rework that I did with the batteries. is it possible to check the charger output ? . . . does the charger turn on ? fuse problem ?
@@designandbuildguy I have checked all connections and fuses. The charger turns on for about 15 seconds then kicks off. If I plug it back in right away nothing happens, let it sit for 15 minutes and plug it in and I get another 15 seconds then it kicks off.
@@AEMansell could be that there is a bad connection somewhere, which at times are hard to find, I replaced my charge port on my cart as it was acting up the same way. Or it could be that the connections are not properly configured ? + / - ?

Coolest grandpa ever
Most of videos I watched showed some type of holder on top holding the batteries. Did you end up ditching? Thank you
yes, as we don't ride on rough bumpy roads it is not a factor, however a bungee or two might come in handy
How are they holding up? In the market for new 12volt batteries but like you said you can save a lot by just buying marine batteries. Please let me know!
Doing just great, I'm pleasantly surprised and so very happy I did not have to buy expensive cart batteries such as Trojan !!

Did you need to replace the charger as well
no, used the same one, works fine
Does your regular charger work on batteries or did you have to get a different one

@@designandbuildguy Thanks for info going to swamp my Yamaha cart over to 4 /12 volts also it ridiculous what Trojan wants for 6 batteries

How are the batteries doing now?
they can take me over 3 miles in the neighborhood without worry !
How are the Walmart batterys doing ?

Where did u get the volt meter at?
Amazon . . . www.amazon.com/gp/product/B08BX13TYY/ref=ppx_yo_dt_b_asin_title_o07_s00?ie=UTF8&psc=1
What's the runtime with the 12 volt, I'm guessing a lot shorter runtime?
actually, in my neighborhood we cruise around for up to two miles and still have a good charge, around 53v start to 49v finish . . . works for us, maybe a golf course run, but not sure as I don't golf

Oh, that's news to me. Never heard of 8 volt LED lighting. They are usually either 5 or 12 volt diodes.
All 48 volt carts I've ever seen use 6 - 8 volt batteries.
I did this and now the old charger doesn’t work. Any advice?

Was hoping the video showed the properly way to wire for 48v. But wasted 5 min of my time.
You put four 12 VDC batteries in series to obtain 48 volts. If you don’t know something that simple, you should not attempt this project.
If you can’t understand basic electricity, series and parallel you shouldn’t be touching anything 😂
