Golf Cart Upgrade, Lead to Lithium Battery, EG4

Let's put a new waterproof lithium battery in this old Golf Cart.
This is a 2003 Club Car Golf Cart that came with a 48V lead acid battery. We are swapping out the old lead acid batteries for a new 48V (51.2V) Lithium. The battery is a 100 Ah, 5.12kWh, LiFePO4, sold by Signature Solar under the brand EG4. The type we are using is waterproof.

Nice to see you back David! Great job on the golf cart! I like the off road suspension on the golf cart.

[@Roll2Videos]

Holy crap! I didn't recognize you Dave

[@hometheatre1706]

Woah, this new look made David almost unrecognizable..😄 Cool new style! 🍻

[@FlashTwoSix]

David looks like a younger version of the Una bomber. lol

[@SOLDbyYOU]

ITS NOT DAVID !!!! It’s an evile clone… that ate the real David ! If he raises his pinky…RUNNNNN !

[@paulbarrette2557]

Wow ... what happened to your head. I like your new look.

[@nola2635]

Be careful if installing this in a golf cart. On the battery manufacturers website for this battery, they have a disclaimer that says, "**EG4 (48v) Waterproof batteries are not a direct swap drop-in option for GOLF CART or ELECTRIC ATV application due to increased amperage during ignition / loaded acceleration moments."

[@DavidPozEnergy]

I agree you need to be careful. Things like, aftermarket motors, or larger diameter tires, will increase the Amp draw. In this case, it's been working all summer just fine.

[@offgridwanabe]

Put a 300 watt solar panel on the roof and never charge again. The new look is awesome but must be hot for the summer.

[@wango556]

You’ll need a charge controller also.

[@TheWickerShireProject]

OMG I love the wild Look! Cave Dave! Look like you been off grid for 6 Months. Grow that beard out brother!

[@obiebrown]

100% move battery to the passanger side and put a small 12v cooler in there :) that would be GOLD! Put to FREEZER mode on cooler and ICE COLD BEERS!!! :)

[@ugetridofit]

How did that current clamp read right when it was on AC ?

[@davidkettell6236]

that is what i thought ,but i am sue he aught that minor booboo.

[@atomicsmith]

Inrush measures peak amp draw, shouldn’t matter whether AC or DC.

[@CSEV661]

It would be fairly cheap and simple to also add a single 100-200 watt solar panel on the roof as well as a solar boost charge controller to charge the battery while driving. I've seen others do this as well.

[@DavidPozEnergy]

I agree. He has already tossed one on the roof with just a ratchet strap. Ha. It's been keeping the battery charged.

[@Comrade_YG]

Keep your hair that way do not change it

[@atomicsmith]

It would be cool to use one of the EG4 all in one charger/inverters. You could charge it from grid or solar, and you’d have 3k watts of AC wherever you went!

[@kurtsandy766]

Wonderful beard and longer hair! Very manly! Hopefully the beard is here to stay! Woof! Great video, per your usual quality! Woof!

[@TheNicko773]

Good work on going lithium. Tell Pat it's a Club Car DS not a Precedent.

[@bartonfisher1538]

I'd love to see some real world tests, like how long/far/fast you can go on a full charge. What is top speed?

[@schoolboy6633]

I just bought a 2022 EZGO S4 Elite & they told me it can go 35 miles on a full charge & it goes 20mph! They deliver it in the morning so if anything is different I'll let you know

[@stephengilstrap]

@@schoolboy6633 My Club Car goes about 40 miles per charge with a Bigbattery Husky 48V LiFePo4 battery. Also goes about 37-38 top speed.

[@Rickmakes]

I help my in-laws upgrade their backup sump pump battery to a Chins 12V 100Ah LiFEPO4 battery. They ran their pump on it for 4 days and it still had a lot of juice in the battery. Their old lead acid would only last an hour or two. A new lead acid would have lasted longer but LiFEPO4 was the way to go since it will perform for years to come.

[@allenconley6243]

isnt that a club car ds? and not a precednet

[@kevinmills5293]

Who are you dude? What have you done with David?

[@allan80supra]

wow it's David Poz wilderness adventures! epic beard bro! :) need a hot rod golf cart video, bump that voltage up! :)

[@LithiumSolar]

Such a simple upgrade but makes a huge difference. Nicely done. I'm still trying to find me a cart for the right price. They don't seem to come easily around here (unless you're willing to pay $5000).

[@Roll2Videos]

Me too! Waiting till the fall.

[@dennis1954]

Where’s David and why are there two bearded guys doing a video on his channel? That bearded guy talking sounds as knowledgeable as DavidPoz is and as interesting too. Great video as usual.

[@steffen1182]

Wow, beardet David surprised me.

[@theborednerds]

Lmao your hair and beard

[@yodasbff3395]

Awesome conversion 👍, how does the price and range compare to the lead acid batteries? I didn't recognize you, you need to take one step closer to your razor blade.

[@theremyyoutube5431]

to limit current for the motor, just use an inductor

[@garymucher4082]

Interesting in this change over. Can you tell me if there were any differences between this battery setup and the previous lead/acid battery setup concerning speed. Did it give more top end? And what was the cost to change over to Lithium?

[@fisherus]

You have a Yeti running your channel, David? He might have eaten you from the sound of his voice. Now I know why you never answered my emails.

[@davefroman4700]

Now he just needs to add a 450w solar panel to it. You will never worry about charging it again.

[@user-ol2sm9jq9g]

David love the new style! I want to do this on my own golf cart but I am going to build my own batteries from the cell packs from SS.

[@danieldougan8550]

Great video but with all due respect, how did you get that werewolf to sound like David? LOL And I thought they were eight volt batteries ??

[@witherow321]

It looked as though you had the meter on AC amps when you recorded the max inrush should have been on DC

[@jfh400]

A+ beard

[@jeffclark4008]

You said that was a 2003 model, but you put a 48v battery in it. Was the motor upgraded to 48v at some point?

[@serverrackbatteryusa]

Great and interesting video again.

[@carlosramosjr7266]

Bro the beered lookes good man i haven seen you conce iv instaled my solor system im glad youre doing golfcarts naw

[@Sylvan_dB]

Pull up against an immovable object. Floor it at full stall. Try again in reverse. Sure wish I could score a deal on a "dead" golf car like that!

I need more David Paz videos they're the best thank you

[@TonyPham-Creations]

Hi David, do you know when this battery will be available again?

[@gregb1714]

Who is this new guy?!? lol

[@ralphbell1786]

I honestly didn't recognize him until I heard his voice.

[@curtw8827]

It appeared the clamp on ammeter was set to AC?

[@ZZTwinCam]

By doing a lithium battery conversion on that old cart, You’ll have more into it than what it is worth. Seems to me like a waste of money.

[@Eastcentralstainingco]

Carts aren't like cars. There isn't a lot that goes wrong with it because of age.

[@troyrowy6709]

Was that clamp set to AC amps

[@oliverschurr46]

what about all that hair??

[@oscer1111]

my god that facial hair !

[@CncObsession]

Hilarious the facial hair!

[@hhuuzzzzaahh]

hair like a grass hut. also, rad cart.

[@ForwardGuidance]

Awesome! The new look suit you very well.

[@JuanGonzales-or6pu]

Hi David, Great Video. long time viewer here. Can you just confirm when you tested the inrush Amps @92, the clamp meter was correctly set at DC. I ask because the first test showed 72Amps, the meter was at AC. As you know, Will not show correct measurement.

[@fatfreesalami]

it looked like it was on AC for both tests. not the right setting.

[@windsurfertx1]

@@fatfreesalami yeah I was wondering about that measurement too. clamp on ammeters is only supposed to work on AC.(they are transformers). It could be that modern clamp on meters have Hall effect sensors built into the jaws. I'll have to study into that.

[@callmebigpapa]

I was watching this and thinking "who is this guy he is so familiar" .......at the end of the video I look at the channel image and it is David.....LOL

[@TeslaAddicted]

was the Clamp meter in AC mode?

[@stickershocksmith2576]

Your amp clamp is ac not dc

[@randycollins5981]

Hey David. Have you seen the new EG4 6548, , i hope they lone you a pair to test out, That would be awesome .

Bro your link is just to there page not a product how can I support check your links like a buyer il come next week and try it again

[@DavidPozEnergy]

Hi Mike. Thanks for letting me know. It looks like Signature Solar changed the exact address of the waterproof battery, so it defaulted to the home page. Here is the new link, and I'll also update the description. Thanks again. signaturesolar.com/eg4-wp-lithium-battery-48v-100ah?ref=4_rHcgZ9x-TiF-

[@Eastcentralstainingco]

Great video

[@SOLDbyYOU]

Dear Dr Poz’ Evile clone… What happened to David? I am not “ afraid” of building a batt bank with BMS from raw goodies… BUT … it this cost effective.?…. Considering the eight year warranty on many golf cart batteries… makes me think that “ one 48 volt , 105 amp, 200 constant discharge” battery sells for approx $1200 - $1500 ( +/-)…. So two equals approx $2800… with the eight year warranty and the independent redundancy … if one batt fails…. Baby the golf cart and limp home… PLEASE…. Disagree with the above logic! I would LOVE to buy raw cells, plus two or three BMSs… and build a very cost effective batt bank… to use in both my ( wife’s) golf cart…and as a great short term power system for our small house. ( yes I get “ batts in series adds volts and batts in parallel adds Amps) Also again please disagree with the following…. I have been reading that the golf cart “ A/C Motor Conversions”, can net a 20%-40% increase in efficiency and therefore “ range” ( miles per charge)… BUT …. That conversion costs over $2 kilo bux … BUT…. if I keep my dc motor and controller… and buy another $2000 ( or less) in LiFePo batteries… ( if I have a 48 volt , 105 amp hr batt pack and just buy another identical batt pack) By spending the money on batteries I “ nearly double the capacity” of the batteries (range)… And I have redundancy … AND ..I have more capacity for the home ( small) power backup . I am an instructor in a different industry and I teach ( qualify) other instructors. I stress that “ I LIKE learning that I was mistaken about a concept because…. I LEARNED “. So please… shoot me down… Or please recommend some of the raw parts. Thx Ps .. my “ other industry”… you are welcome to pm me… I can do the Battery build. Thx

[@Erik_Swiger]

I really, really want a small, cheap, electric city car. No power anything, no air conditioning, extremely basic. Just something for traveling 50 miles while running errands, or whatever. Since EV makers seem intent on making cars with 1,000 mile range and heated steering wheels, maybe I'll have to convert a golf cart to finally get my small, cheap, electric city car.

[@Dutch_off_grid_homesteading]

heya that is nice with just 1 batterie driving that golf car into the future

[@lithiummoto]

THere's a reason this battery from sigsolar is $1650. When all the other golf cart batteries are around $2500 ??? , you need to answer that question.

[@evjedi4061]

OK Grizzly Adams. Lol 😂 good job Maybe you can get a sponsor from the shave club. 🤷‍♂️

[@bubbacat5392]

Dang Dave, the wild man look. Did your Dollar Shave Club membership run out ?? 🤣🤣🤣 Rock on Bro. 👍👍👍

[@mrrewog]

Hey Grizzly Adams, didn't recognize it was you until you started talking. 🐻

[@tommybenton-c3p]

Has any one made the switch of batteries on a older electric zero turn mowers sold at the big box stores. The ion batteries last about four years. With the four 12v 100 AH batteries connected in series new I was getting one hour thirty minutes per charge. Last year I was lucky to get thirty minutes. The company changed its new models to Lithium batteries, so support over the next couple years is maintance going to be suspect. The meter is a little flaky but I am happy with the unit. I have about two and half areas to cut and need at lest two hour run time. I am looking for a solution so I am not buying new batteries every four years. thanks for a great video.

[@bubbawubba2307]

Don't think those LiFePO4 batteries like being charged with insane currents. Like 100AH battery being charged by 100amps. I think the 280AH can handle it.

[@CityGirl33]

Cost ?

David...didn't recognize you and skipped over the video until now. Nice off-grid look!

[@jessefaircloth8321]

Have you had any experience with High/Low Temperature shut off in the Summer and Winter uses?

[@realvanman1]

In all likelihood that golf cart has an electronic motor controller which means that the maximum power draw from the battery occurs at a higher speed than zero. Specifically the speed where the controller is no longer stepping down the voltage (and stepping up the current) to the motor, and instead has the motor across the line. It would be interesting to put your peak recording ammeter on there and do a standing start to full speed run, and see what current reading you get. Then put the ammeter on the line to the motor, and you'll see a much higher reading when the controller is dropping the voltage and raising the current.

[@pickandstrum]

Interesting conversion and after watching this video I did look in to the signature solar battery, but for my cart it is a 36 volt and the BMS in the 36 volt battery has a much lower discharge amp rating than the 48 volt and I am not sure it will work for me. The 36 volt EG4 WP only has a 102 Amp discharge for 10 sec and the 48 volt is rated at 150 amps my concern is the BMS may trigger under a heavy load, my cart is a stock cart but finding the amp dray for a stock cart is pretty hard to find online.

[@jamesmoore2007]

Did you loose your home? I hope you're not homeless man. If not I'll send you a razor

[@tomsterism]

Is it possible to identify the approximate cost of the groovy Lithium Iron Phosphate battery, its weight and cost? Also, as to performance, will this run longer, faster, etc., than the regular deep-cycle lead acid? Great video, by the way!

How did you grow that much hair and beard in only 3 months?!

[@lelandeggleston1041]

This is exactly the video I was hoping you would make. I have a ranger ev that is need of a battery upgrade.

[@yellowgreen5229]

Shame you didn't put a few batteries to the same size and weight as the lead as that would have been an interesting test. Why you didn't use 12v batteries is beyond me.

[@ssteele1812]

Really makes me wish that the golf cart my mother in law bought last spring was already electric instead of gas. She can barely drive is because of the issues with the gas motor and the starting battery constantly running down.
