Lithium batteries for golf carts are gaining in popularity like crazy. Newer technology in lithium batteries, such as in Tesla cars, have transformed long range capability in a compact battery pack. The benefits of doing a lithium ion golf cart battery conversion are many! An average lithium battery can cycle between 2,000 and 5,000 times; whereas, an average lead-acid battery can last roughly 200-300 cycles. That's about 10 times longer life than a lead acid pack.
Another huge benefit of lithium ion golf cart batteries is their weight. Lithium ion batteries are about 70% lighter than their lead counterparts. On average, a golf cart conversion from lead acid to Lithium Ion will save over 300lbs! This positively impacts the cart's performance and reduces wear and tear on a golf cart's controller, motor, suspension, frame, and tires.
Lithium golf cart batteries are able to accommodate higher voltage levels compared to traditional lead acid batteries. This allows your motor to produce higher torque and while optimizing the efficiency of your electronics.
Each of the Lithium Battery packs that BigBattery.com sells comes with a built-in Battery Management System (BMS). This will ensure that your batteries are never over-charged or over-depleted.
Most lithium-ion batteries operate around 99.1% energy efficiency compared to 50-80% with lead acid. This efficiency impacts charging speed as lithium ion batteries can reach a full charge nearly 50% faster than lead acid.
In this video, I basically transform my lead acid pack to a Tesla golf cart! I chose to upgrade to the Tesla Model 3 2170 lithium ion battery pack. It only weights 68lbs and provides 95ah of power. On one test run after this video I was able to go 25 miles with 25% battery capacity left. Could I have gone 30 miles? We'll find out one day so stay tuned!
I will explain how to perform a lithium ion golf cart battery conversion. One of the reasons I chose the Tesla Model 3 2170 pack is because it is the same size as my previous Trojan 8 volt batteries so it fit in my cart perfectly. I'll also list all the items needed and show you how to wire the system properly for a perfect DIY install. When you are all done you can tell your neighbors that you now have a Tesla powered golf cart!
Thanks for watching!

Wow!! Great video! Can’t wait for you to start on the next one!!
Just found your channel tonight. Really thankful for your thorough explanation of the lithium setup
Glad it was helpful! Good luck! 👍
This is a really well laid out and presented video. Your install and cabling is super clean!
Thank you! Appreciate the nice comment!
First thing I noticed as well. Looks beautiful inside! I’m currently in planning stages of my DS to receive the 48v hsky unit from BigBattery.com. Little different set up for the single unit but I think it’s going to work out nicely.
That was an awesome video. Sweet upgrade to an already awesome vehicle. Now all you need is a solar panel on top of your hunting cart roof. I like that you cruise around in it in your neighborhood.
Thanks for commenting! Glad you enjoyed it!
Duuudde!! Just ran across your account, what a set up!! Thanks for all the information. Great explanation and again. REALLY NICE SET UP!
Thank you for the compliment! It’s been a good rig so far!
Fantastic system. Thanks for the great explanation. Super clean system.
Thank you for the compliment!
Man that is one sweet ride. I want one!
This video is awesome! Thank you for showing how easy our lithium batteries are to install as well as how much gain and efficiency is involved!
Would it be possible to connect 4 of those battery packs to double the capacity? He would have room under the rear seat.
Yes, you absolutely could!
Thank you mate, very insightful, cheers!
You are welcome!!
howdy! You saved me! I just got 2011 stealth 4wd utv....batteries are a mess and I decided to go lithium....I will be memorizing this video over the next few weeks for sure...thanks
Awesome! You are welcome and have fun with it!
Very tidy install and wiring. Nice!
Thanks! 👍
Hey HH! Love the video. I can’t wait to see it on your farm pulling a trailer load of hogs... God bless, and keep the Vid’s coming.
Thank you for watching! Keep an eye out for some future vids. God bless!
@@TheHandyHunter have you notice an increase in battery life with the lithium batteries? I was curious. Thanks
@@Tomthormeyer Big difference! I did a range test on pavement and got 24 miles with 25% battery capacity left. Next, I will do a range test on the farm for a comparison so stay tuned. Hope that helps.
Hey HH!!! You know that hot rod would be illegal in the Villages!!!LOL
LOL...I don’t know if it would even compete over there. Those guys go all out! Thanks for watching!
Come build stuff with me in Belize!
Thanks for the info.
You are welcome!
This looks great! I have a hunting cart 4 we . I will certainly look into this option.😎🇺🇸🇺🇸👍✝️
👍 nice to see there are more lithium pack alternatives. I'm currently building another stol plane. I'm planning on electric in it also. Will be using a 40 HP 89# of torque. With Peak efficiency at 3000 rpm And 4 Tesla packs. These packs are flatter allowing two in each wing. This Plane will be used mostly for competition. But with its glide ratio and the motor regen capability. I'm hoping for close to two hours of flight time. Which at top Cruise speed should get me around 250 miles. More than enough to take a leisurely early morning or Twilight light flight.
That’s awesome! What a cool project! Shoot me some pics when you are done…would love to see it👍
Hey HH, love the video! Great information you shared here, this is something that I definitely plan to do in the future on my club car DS hunting ride. Quick question for you. Are you at all concerned about the #6 AWG wiring on the Anderson cables with the high torque motor and controller upgrade? I personally have the same motor and a 600 amp alltrax controller which both recommend #2 AWG cabling.
I had the same concern too but so far everthing is working great. I shortened the provided cables as much as possible since they were extra long but you could create your own 2awg cables with anderson plugs going to your bus bar. Keep in mind that the short internal cables are still 6 awg so you can’t completely eliminate the smaller cable. With that said, I haven’t had any problems in my initial use and my motor runs about 40 degrees cooler on lithium vs lead acid! I plan to torture test them on my next trip to the farm. I want to pull a heavy trailer loaded with wood to see how it performs and whether I can throw the breakers. So far so good, lots of pepp, power, and range with a little more speed thrown in. Good luck and Merry Christmas!
Great video, converting mine. What did you do about the interlock that prevents operation while charging since all the old charging cables are replaced.
I removed all that so the cart will actually move while charging. I either put it in neutral or turn the key off. Hope that helps.
Excellent Job Friend......
Thank you!
Man i love what you ve done with your cart! The welding and fabrication is impressive. I would like to add suspension to my rear axes and wandering. Would the shocks alone do well by themselves without the top links?? Im trying to minimize the amount of welding. Also where would find the top links ? Robby
Hi Robby, you have to have the top link to keep the whole axle from swaying side to side. It also keeps your axle from rotating forward when you hit the gas. You can find the top links called heim joints on ebay. You can find the weldable heim joint brackets on ebay is well. Hope that helps! Good luck.
Looks great. Very clean build. How did you secure those battery cases down?
Thank you! I used an adjustable rubber strap and clipped each end to the frame. Nice and snug. Hope that helps.
The led acid batteries need airflow because of the off-gassing. LiPo needs airflow but because of the heat dissipation. So don't seal these up without giving them a way to get rid of excess heat. Use a porthole with a small fan that turns on at 75 degrees or something based on the specification.
Great video and awesome illustrations for the wiring diagram. Using it in my build right now. My apologies is you answered this before. Why 600amp buss bars?
What’s the amperage on your controller?
I have a 500amp Altrax controller. Hope that helps.
Good video thanks. Did the batteries stop holding a charge or a different issue?
Internal cables too small, breakers tripping constantly, and range drastically shorter way too soon. I would build my own batteries next time.
@@TheHandyHunter thanks for the info!
Just started watching this episodes and you may cover this later in the video, where did you source these batteries?
Check link down in the description. I found the best deal and help at Bigbattery.com. Hope that helps! Good luck!
ok in your description on your amazon parts i do not see the shunt for the bus bar, also i'm confused about the accessory bars are they on the page. thanks
Hi Dale, sorry for the delay. The shunt comes with the Coulometer. Not sure what you mean by the accessory bars…let me know. Thx!
@@TheHandyHunter so i am thinking about buying the same Batteries that you have, 1st what has been your opinion on your setup 2 i currently have a voltage reducer with a fuse block and ground block will that be sufficient with this system? thanks
It’s a win all around. Improved under seat storage space, better power to weight ratio, better handling, less wear on suspension and brakes.
For sure! Many benefits to a lithium upgrade!
Love this cart! I’m currently converting mine to petrol.. 440cc supercharged engine.
That sounds awesome! Shoot me a pic when you are done and I’ll post it on our community board. Good luck with your build!
@@TheHandyHunter thanks mate will do! Got it running today took it for a test drive it goes really good!
@@TheHandyHunter hey mate I finally finished my cart how do I send you a picture?
Hhsteve@protonmail.com….thx!! Can’t wait to see it!
Hey..Nice job! I was wondering, are you concerned about water/debris getting into those bus bars and such? Your wheel wells are open to inside that battery compartment. Also, your charging port is exposed. For an off road cart, that would concern me.
Not concerned about the bus bars but it can get really dirty inside so it needs to be cleaned. I pressure wash the inside but avoid direct hits on controller and battery boxes. Never had a problem. Also, there is a cover that goes over the charging port when not in use. Hope that helps!
Hey. So this was a great video. But, as I am a newbie and I wanted to understand this a bit more. I love your diagram you drew up. But I am not sure where the solenoid is as well as the controller (I think it is) is on the wiring diagram?
The “main out” cables on the diagram will go to your solenoid and controller. This diagram was just meant to show the difference in pre-controller setup using lithium vs lead acid. I hope that helps!
Great video! Did you say you put a new motor on your cart? If so can you tell us what kind you used and were you got it at. Thanks.
I installed a torque beast by AMD. I’ve got a link to it in our Amazon store under Hunting Cart. It runs awesome! Hope that helps!
How did you secure the diamond plating? Screws/Bolts??? and where did you get it from??
I get my diamond plate at a local steel store but you can get it at Home Depot or Amazon as well. I just used stainless metal screws to secure. Good luck!
have you tried towing anything with this? if so are you using the stock motor and how much did you tow?
I’ve towed heavy with the original motor and with my new motor. I abused my old motor which was about 40 years old and can’t believe how well it held up. I have the beast now and it’s great too. I tow a 4x6 trailer loaded with firewood till it can’t hold anymore. It probably weights 2,000lbs completely loaded with big logs. Cart does fine but I’m also pulling on flat land with decent roads. Once you get it moving the amp draw drops a lot. I may be testing some new batteries from RoyPow soon with 200 amp 30sec capability. I hope that helps. Good luck!
How’d the mileage range test go? Don’t regular batteries already get that, maybe more?
Take a drink every time he says super excited.
Just don’t hit the hard stuff! 😂🤣😂🤣
how did you mount your battery monitor to the roof? Looks like Velcro but I feel like that wouldn't hold. I want to mount mine to the roof as well.
I took a junction box face plate and cut out an L shaped bracket and then wedged it between the bar. I used double sided tape to get it to stick to the faceplate and it holds well....never comes off. Good luck!
Can you give me some links for your buss bars and coulometer I’d really appreciate it ty in advanced
I am in the middle of a similar conversion. New controller, solenoid, and lion batteries. Did you need a obc bypass for this setup. I cannot get any click out of solenoid but have voltage everywhere.
I don’t have an obc on mine. May want to double check your throttle wiring to make sure it’s turning on the selenoid.
Where did you purchase the upgrade motor from? Curious on the price. Thinking about doing a conversion from my gas to electric. Could gain a shit ton of storage. And use for hunting.
I bought it off Amazon. I have a link to it in our Amazon store if you want to see the current price. It was around $600 if I remember correctly. It’s really strong...real happy with it so far. Good luck!
Good stuff
Thank you!
In addition to all that below, my set up does not use a bus bar, just a single terminal post for positive and another for the neg.
Hey Handy Hunter!
Thank you for posting a very informative video with our New Model-3 Battery Packs. This will help a lot of people understand how to do their own DIY Lithium-Ion Conversion and scrap scrap the heavy lead-acid batteries! We hope you enjoy your "Maintenance Free" batteries for 8-10 Years! Happy Hunting! : )
You are welcome! I can’t believe I didn’t do this years ago. Batteries have come a long way! Thanks for pointing me in the right direction👍
Great video sir.. Does the cart ride rougher now that its a lot lighter..?
The front is fine but the back is a little stiffer from the loss of weight but nothing that bothers me. I usually throw a bag of corn on the back to help a little.
I did a very similar set up and mine is definitely rougher. still thinking about how to take some of the bounce out. Im not doing independent suspension. I've spent enough money...
I got that temperature gauge in the mail today, did you have to make the wire longer so you could run it to your motor from where you mounted it?
Yep, I remember having to extend it with some light gauge wire...real easy to do. I think if you look closely at the wire you can find the neg/pos marking. Hope that helps!
Have you had any issues running your winch off the bus bar given the regulator is just 60A but the winch can pull 180A at 3000lbs? Or do you just make sure not to pull that hard?
My winch doesnt work off any of the regulators I’ve tried. I’m thinking of adding a new separate battery for the winch. Thinking of building a 16v or even trying a 24v😬. I just know that my winch ran like a scolded dog on 16 volts with lead acid. I’d like to get that performance back. Let me know what you decide.
Looks like you have a 500 amp controller. These packs have a 126A peak discharge so did you have to turn down your controller?
I did not but I rarely hit that high of a draw for very long. It does happen sometimes when pulling a heavy firewood trailer for a while and the breaker will throw on the pack. I just flip it back on and take it easier.
How did you mount your battery monitor and temperature gauge? I kind of want to do the same thing (mount up high so easy to view). Can't tell from your video and don't see any brackets on your amazon store. Looks like you may have used velcro? Also, for your battery monitor, did you wire it through your key switch so screen only on when key on? OR, since you have on/off switches on your batteries, did you simply wire per instructions and turn off your batteries when not using so no power to accessories? I bought the same monitor and planning to install this weekend.
Hi Troy, I took a metal junction box cover and bent it so my monitor would angle down a bit. I then wedged it in place for a tight fit. I used double sided tape to make it stick and so far it’s been great. I did not wire into key switch because it draws little power, goes dark when not in use, and I flip off the battery breakers when not in use for extended time. It’s good to mount high where its protected from sun and rain since I dont think it’s very weatherproof. I love mine! Good luck and let me know how it goes.!
I like the electric idea you can really sneak up on game with it! They'd hear a quad coming from a mile away. I'm thinking my electric geo metro project would be better served with golf cart parts as most car drivetrains and axles are going to be way too big and heavy. I'm just afraid the state's brain will break when they still demand I go for emissions testing and they cant find the tailpipe.
That’s awesome! What a cool project!
Do you think this would work with stock controllers and motor or would it need the upgrade?
Should be fine as long as you stay with the same voltage. Good luck.
Steve if you haven't seen it, look up DIY Solar Power with Will Prowse and his second installment of the Off-road Solar Golf Cart. That inverter/charger he added is a darn appealing.
Thanks! I’ll check it out! I love his vids!
@@TheHandyHunter Look forward to seeing your thoughts on that mod. Seems like it could be very handy to have access to power tools out in the field like that. Granted, not sure what all tools it would be able to power but certainly worth putting pen to paper to find out. Plus multiple charging capabilities is also nice.
Good Afternoon,
I have a 94 club car ds that I am wanting to convert to a similar system, I saw the diagram in the video showing the power coming from Buss Bars to main out.. Can you show me how you have the rest of the power wired to the controller, pedometer forward reverse etc? I'll be switching to the lithium when the current batteries are dead.
Hi Jay, that’s why I stopped the diagram where I did because that’s where different brands of carts start showing their differences in how they are wired. Luckily, there are lots of wiring diagrams for DS carts on google or the internet in general. They will show you how to wire the F&R switch, the controller, motor, and throttle. If you are buying a new controller chances are they will have wiring diagrams on their website. Lots of good resources out there that explain it better than I can. I hope that helps and good luck!
Awesome info! I've been looking at converting to lithium and could only seem to find manufacturers sales pitches. Thank you for sharing!
You are welcome! Glad it was helpful!
Your Amazon store has a link to the RMP 3003 H22 Aluminum Diamond Tread Sheet, 12 Inch x 36 Inch . How many of these did you need for your conversion?
I used 2 and had some left over. Hope that helps!
You have a great upgraded adult version Power Wheels.
LOL…thank you!!
Have you thought about doing the 4x4 add on motors for the front?
Thinking about doing that on my next build or installing a polaris transmission with 4wd to front axle. Not sure which direction I’ll go yet?
Your batteries look great compared to my old dirty Trojans!😂
I know the feeling! Thanks for watching!
just read your unrecommendation on big battery....and noticed your list of alternatives,will be checking them out
Check them out and if you are handy you can build the best set on your own. All you need are the 3.2v blue blocks and add a Daly BMS and you are set. It all comes from China on Alibaba but all lithium batteries in the US pretty much comes from there anyway. Much cheaper doing it DIY too. That’s what I am doing next time. Good luck!!
Did you consider just mounting the charger inside the cart since you have so much space for it now? That's what I have been thinking I'll do, so that I just have to plug into any wall outlet anywhere I'm at.
I wanted too but this charger is not waterproof and I pressure wash my cart often. I may upgrade to a new charger in the future as having it mounted onboard is a huge plus...especially since these chargers are very light! If you can do it I would mount it onboard for sure! Thanks for commenting!
What gauge wire is that going from the battery's to the motor? When i upgraded my motor and controller I had to swap to 2 gauge welding wire I think. Those wires you were holding looked smaller than that. I could be mistaken, just curious. Other than that your build looks awsome. Also what is the total AmH on the new batteries? Cost?
Hi Jace, the gauge from the battery pack to the bus bar is 6ga. From the bus bar to controller and motor is all 2ga. So far it’s been fine and motor runs about 25degrees cooler over lead acid with all 2ga. This pack runs around $2,399. Not cheap but lithium is long life and low maintenance. Good luck and hope that helps!
What's up HH glad to see another video and as always very informative. I was thinking of getting the same kit. I have a few questions that hopefully you can answer. Do you think the winch is going to work with that voltage regulator with the about us draw, I know you had it hooked up on 2 batteries (16v) and if you can tow that trailer with a load to see if the BMS will shut down. Finally can you do a diy infrared light with solar for our night scopes. Great job keep up the informative videos👏👏👏
Stay tuned as I’m hoping to test out the cart at the farm this weekend. The winch worked fine at home but I didnt put it under load. On 16volts it came on immediately. On my 12v reg I have to hold the button down for about 3 seconds while the lights blink before it comes on. I think it’s delayed because it’s loading the capacitor? It does seem to be straining the regulator a bit so I’m thinking I might find a slighly higher voltage regulator in the 16 volt range (if they even make them) and connect the winch to it separately. It would be an easy install. My current 12volt reg is 30 amps and hasn’t blown a fuse but not sure about the start delay and why my lights shut off while pressing the winch button. I’m still getting used to this setup but it’s been great so far. I want to do a range test on the farm. I got 25 miles at home on pavement with 25% battery life left. If I get half that at the farm I’ll be happy. My motor runs a lot cooler now too👍. Keep an eye out for some future updates. Thanks for watching!
I’m ordering an upgraded 60amp 12v regulator as my first one blows a fuse with lights on while using the winch. It’s a 30amp and my new one is 60amp so that should work a lot better. Whole cart is working great except for the 12v regulator which will be fixed soon. Just wanted to give you an update.
@@TheHandyHunter I can wait to see the updated video once everything is lined out. Trailer full of pigs and the winch pulling them up a tree to get cleaned out.👍
What kind of range do you get with this setup? Love the videos!
I got almost 25 miles on pavement with 20% battery left. I would expect less for off-road use but have yet to run a full test. Hope to do soon.
where did you find that pigtail you used in the video?
If you click on our Amazon store link down in the description I have all the pigtails in my hunting cart ssction. Hope that helps.
Hey Handy Hunter! I've checked out your tube long ago and it helped me with my conversion, thx, very appreciated! Year plus later I have issues, was wondering if all is good with your set up? I did mine set up similar but your's is by far a whole another level! A couple of questions for you. I have the BigBattery 36v gator max kit 120Ah 5 kW! My charger never shuts off, according to them that is correct. How about yours? Also fully charged shows 45.5-46v, cart is a 36v. Does your's go well over 48v fully charged? My cart stopped running, appears to be controller, spoke with a mechanic and he believe the controller has been getting too hot and the resistors are burnt, wondering it it's from to much voltage! I am getting the full voltage on cart parts using multimeter! Emailed Big Batt. about this and back initially on set up about to much voltage at full charge they stated their computer board inside would not let that much voltage to cart and that even though the charger does not shut off the board will not allow it to over charge. Does any of this happen with your set up?
My charger slows to a trickle as it reaches full charge but never completely shuts off. My 48v pack will hit like 55 volts at full charge so yours is normal for lithium. Have you thought about upgrading to a solid state system vs the coils? You will be amazed at the difference and will work better with yiur lithium set. Hope that helps!
I have a 2019 yamaha drive 2 what will i need for conversion?
My diagram in the video will work for pretty much any cart. The bus bar setup makes it easy to connect all your power from your batteries and then to your controller, etc. I hope that helps.
Do you think this would work with a 5kw 600amp Navitis AC system?
Offroad or pavement? I think you’ll be fine either way but offroad can be more demanding. I run a 500 amp Alltrax and it’s been fine. You may want to call Bigbattery and ask their thoughts as well. Good luck!
What size controller do you feel is the best for optimizing cart performance without tripping the BMS ?
I run a 500 amp Alltrax and I havent tripped it yet. I want to do a torture test next trip to farm and pull a firewood trailer uphill for a ways and max out the amps to see if I can trip it. We’ll see!
@@TheHandyHunter I’m really torn on going to the lithium making the cart so light that I lose traction. Sorry for all the questions but really like learning from your experience. Love to chat on the phone if your comfortable. My email is robbydwhite@hotmail.com. You can send ur info.
Do you have to replace the controller and motor or is it really as simple as replacing the Lead batteries with lithium?
It’s as simple as switching out the batteries! You may need to do a little rewiring to a bus bar for your charger wires and 12v regulator but that’s all very easy. Good luck and let me know how it goes or if you need any help.
Oh, my lithium 48v pack had slightly higher voltage (peaks at 58 volts fully charged) on the pack vs lead acid (a good thing!) so I had to raise my high voltage cutoff on my alltrax controller to the maximum to accommodate the slighly higher voltage and prevent controller shutdown. You’ll want to put it at max if you have a programmable controller.
Hey what kind of cart is that. Im looking for one to do something similar
It’s an old Club Car
Thanks HH for the Promo Code. Just ordered the Gen 2 36V Li-ion Conversion Kit. My 1995 EZGO Freedom already has the Anderson plug charging receptacle receiver. Should I leave as is or disconnect and reroute to the bus bars? Thanks
You are welcome! Where do your current charger leads go...the battery pack or bus bar? With your new setup I think you’ll be best served to consolidate everything to the bus bar. Hope that helps. Let me know if you need anything!
@@TheHandyHunter Thanks for the reply. The two leads go to the big plastic box under the passenger side seat. I just ordered the conversion kit last night and haven’t started disassembly of the cart yet. My intentions are to basically wire it up similar to the way you did the 48V.
Sounds like a plan. It’s pretty easy to rerun the wire once you install the bus bars. Good luck and let me know how it goes.
Upgrading my cart with Navitas AC conversion kit and stumbled across your video. Looks like you live in our neighborhood. Ha! My batteries are about done so now would be the time to make this kind of change. Did you look at the 48V 6.4kWh Li-ion Kit they offer? It does not state in on their website but their video for 48V Model 3 Li-ion Kit states that system has less capacity (4.6 kWh). I believe you said one of the reasons you did this particular setup vs the 6.4 kWh set-up was for additional storage capacity under your seat, correct?
Hi Troy! If you go to bigbattery’s website and click on the 10 year warranty at the top you’ll see details and specifics regarding their warranty. You’ll love the upgrade and let me know if you need help. Stop by sometime, I’m the first house on the right. Lot’s of carts in this area! Merry Christmas!
Hello, I love the upgrade and was wondering what the cost to do this would be ?
If you click on the links in the description of the video you can see the different price options at Big Battery. You can also see the misc items I used in our Amazon store under Hunting Cart. I try to organize things in our store so people can find them easily. Hope that helps.
Is this a different cart or did you repaint it? Looks great
Same cart, I just repainted it a couple years ago. Thanks for watching!
@@TheHandyHunter did you use rattle can paint?
Yep, and I spray over with a clearcoat to protect. Hope that helps.
@@TheHandyHunter yes it does, I’ve been building a hunting buggy thanks to your inspiration. Really appreciate it
Awesome! They are fun projects for sure! Shoot me some pics when you are done. Keep in touch and good luck!
Hey Handy Hunter. Looking to upgrade an electric cart for a similar build. I live in Appalachia and have some good hills to climb. In any way that you want to reference it, would you say the new motor and controller help climb "X" grade? I know I won't be able to do hill climbs, but with a lift similar to yours I'd like to be able to climb hills around 20 degrees. Thanks.
No problem at all. Are you running lithium or lead acid? LA is 300lb more up hill. If you are concerned you could jump up to 600 amp controller instead of five but not sure you need it. Hope that helps!
I’ll go LA for the weight savings. And may go with the 600 amp just to be safe. Better too much than too little. Thanks for the quick feedback.
Great video! I just upgraded my cart to 48V lithium as well. The problem I'm having is that my lithium battery has a separate charging port (different from the main + and - terminals), and the battery shuts off during charging. My understanding is that the coulometer has to stay on in order to have the right information. So I'm not sure how I'm supposed to wire it up.
When you say your battery shuts off what do you mean? Is the charger shutting down prematurely?
@@TheHandyHunter my battery is a single 48v pack with a power button. When I plug in my charger, the power button light turns off and no voltage is available at the main + and - terminals. Power is not restored until I unplug the charger from the battery.
Interesting. Did the charger come with the battery? It sounds like a circuit protector on the BMS is being triggered...possibly for overvoltage? How long does it stay on before it turns off? What brand of battery is it?
Did you go with a high Touareg low speed motor or high speed motor
High torque...top speed for mine is about 20-24mph
How much of a difference over lead acid was there as far as range, power, etc.....
Got almost 25 miles on pavement at night running lights. I’m hoping to do an offroad range test soon. The power seems stronger I think due mostly to the massive weight loss from lead acid. You can tell a big difference in weight loss. Batteries now charge faster too. Hope that helps!
Nice conttent for a new subscriber. Can you recommend any sources for the carts themselves - used - or for bare bones carts like this one? We all are searching for value and in adding to our own skills to convert that value to fit our own needs, without breaking the bank for new carts off the standard showroom floor. Any help is appreciated. Thanks.
I found mine on Craigslist and know of others finding them on Facebook Marketplace. You may also want to check with your local golf cart dealers to keep an eye out for really old ones that they might not want to fool with. Hope that helps.
What shunt and monitor do you have I like that and would like to add one on my rig
Check out our Amazon store in the description. I have a link to it there. You can also search for “coulometer” and find others. I really like the one I have and it’s a really simple install. They are great for keeping tabs on the system. Good luck!
@@TheHandyHunter I have the same coulometer as you. ?? When you charge your battery does your coulometer show that its charged or do you have to reset the coulometer after every charging cycle? Thank you
It automatically shows the state of charge at any given point. So it will show 100% when battery is full. Hope that helps.
Which torque motor did you go with?
AMD torque “beast” motor. I have a link to it in our Amazon store under my hunting cart. You can see some specs on it there. Real happy with it so far.
Love this cart.
By "charger", do you mean solar panel?
Is this a solar cart? How many watts of panels would you need to charge these lithium batteries? Did you mention the total amperage in the battery bank?
Thank you 😊
Thank you! It’s a 48v cart and it’s not solar charged. I use a lithium battery charger for 48v. Hope that helps!
@@TheHandyHunter thanks a bunch! Your cart is perfect for my island jungle. I just need to charge via solar.
EnjoyBot batteries seem to be the best bang for the buck!!! Thanks for the link!
You are welcome. Good luck!
Any updates on how you like (all of) the new equipment?
So far so good! My only problem is that I can’t find a 12v reg that can push my winch. I think it’s a power hog.
@@TheHandyHunter I was wondering about this. You said in the video you had the winch powered through the converter, did you have it that way with your LA batteries? I have been told more than once that this can not be done due to the amp draw that a winch needs. So far there is no converter I have found that can handle a 12v winch. I also can not seem to find a 48v winch, even though there are stories about them existing. Have you had any luck finding an alternative method?
Hey brother...we think alike. On LA I ran winch on 16volts (2 batt)...ran like a mother. On lithium...At first, the winch worked on the regulator but then blew up. I ordered a bigger one and it only clicks when I try it...won’t work. Currently, my winch won’t work and I’m done trying to find a regulator. I think the only solution is to run a separate 12volt battery in the cart just for the winch. Let me know what you find out...I’m stuck too!
Could you share a detailed parts list of the items needed to make the upgrade exactly as you have. Please and Thank You in Advance
I have everything I used organized in our Amazon store under the Hunting Cart section. Makes it easy to find everything in one place...except the batteries. Hope that helps.
What is the link to your Amazon store?
It should be in the description of the video. Let me know if you cant find it. Thx
Would you recommend a setup like this for a twin motor bad boy buggy
Yep! Just look for a good battery with high output since you have two motors. I assumed the BBB’s are 48volts? You should have many options if you have the room, etc.
@TheHandyHunter yes, it is 48 volts and has alot of lights, radio, etc. But all the lights are led. If I contact big battery are their prices competitive,. Every where I look it looks like about 1000 to 1500 for the setup including charger.
That sounds cheap actually. I’ve only seen prices that low for lower Ah sets which may be all you need but generally the more Ah the more$$$.
Are you running your lights off a 48v to 12v reducer?
@TheHandyHunter yes,. All lights and equipment are running off a current 8 battery setup to produce 48 volts. Then ran to a reducer and then to a fuse box
Did you repaint your cart in canoe since your last cart upgrade??
This is the second paint job since the original camo job....I scratched it up pretty bad...lol.
@@TheHandyHunter I thought it looked different and fresh!
How’d you mount the temp gauge on your motor?
I just used a piece of gorilla tape and it works great!
@@TheHandyHunter Aweome
Is it possible to make this setup solar?
You could definitely add solar to assist in charging but it wouldn’t be enought to run it.
This is awesome! But it is a 21700 battery lol.
I’m curious to what the whole set up minus the cart it self costs?
The batteries run about $2,500 for 48volt setup. Hope that helps.
im assuming the capacity isnt the same, how long can you go between charges?
I got nearly 25 miles on pavement but I typically plug back in when I return from even a short trip. There’s plenty of range for my needs and it takes a while to run them down.
@@TheHandyHunter thats good to know, i have been looking at different options to try and replace the lead acid batteries i manage at work. im just trying to get an idea on how long they can go, seeing the discharge rates are fine and good but thats all in a controlled environment, adding hills, bumps, stopping for people, and adding weight can drastically change those numbers
Exactly! I still plan on doing an offroad range test to see hiw far I can go. Dirt roads, hills, and mud should be a good test. I do all that now with no problem but I usually come back and plug in periodically.
It’s me again Margaret.. :) Ended up picking up the 1995 EZGO Medalist for $300. No batteries, tray is rusted out, controller is fried. Otherwise it’s solid. I’m going to go very similar to the route you’ve gone here (I’ll buy through your store where I can too!). Question is any tips on systems to upgrade to 48v? I’m considering the Beast 36v/48v, need to get a 48v controller, solenoid, etc. When you upgraded to 48v system did you stay with DC or convert to AC?
I stayed with DC. I’m running an Alltrax 500 amp controller with AMD torque beast DC motor. I think Navistar makes a nice AC setup but if I were you I’d call Plumquick motors and tell them what you want to do and they will tell you what you need...and without upselling you! My only AC experience offroad has been with an RXV and it’s not good. This AC setup has a weird torque curve at low rpms but it will fly at top speed. I may look at AC down the road but would have to research more on best approach. I know the Polaris EV uses an AC setup so it can be done. Hope that helps.
@@TheHandyHunter Thanks boss! My dad has an EV, awesome rig but totally different animal versus these cart builds. So heavy, lots of torque and the 4x4 is great, it has its place for sure. I’ll reach out to Plumquick, had not thought about the low end versus top end application!
Nice
Thank you!
@@TheHandyHunter yessir!
Did your winch work good running off the 48v to 12v reducer ? I put a RoyPoy 48v lithium in my yamaha drive and the winch is very weak running off of the 12v reducer
Mine won’t work at all. I blew two cheap regs and then bought a nicer one and it failed too. I think my only option is to drop a separate 12v battery in there to run the winch. When it ran on 16volts on my last system it would pull a truck.
Thanks for getting back with me. Im thinking a 12v battery added in will be the fix. Thank you
One more question, deep cycle or regular car battery ?
I would do a starting battery vs deep cycle…for more amp delivery
Thank you
They’re overpriced, but I guess worth it if you don’t want to or know how to diy. Their expensive version is $2,300+ for 5.3kWh battery kit. I know you can get 1kWh batteries for close to $100 each so they’re charging $1,000+ for the convenience.
can you sent the site with all the diagrams
I could not understand the type of cells this has, sounded like cattle cells, could you explain. Thanks
They are 2170 batteries from a model 3 tesla car. They are basically a bunch of flashlight batteries. Hope that helps.
Same batteries in power tools and laptops
You mention lithium ion batteries multiple times but you links are for lifepo4 batteries which are not the same as lithium ion. You really could save a lot if you look at the individual 3.6v lifepo4 cells. thats what I replaced my 6 -6volt LA batteries in my camper with.
You are correct…The batteries I installed were Lit/ion but the ones I now recommend are LifePo4 because they are better. If I had to do it all over I would build my set out of 3.2v blue blocks using a Daly BMS. Thanks for commenting!
I'm contacting Bigbattery on Monday. Cool video. Really interested to hear what kind of milage you are getting.
Got nearly 25 miles at night running lights on pavement. Want to do an offroad test to see how far I can go. Good luck and tell them I sent ya! Good luck and keep in touch.
@@TheHandyHunter I finally got around to converting my cart. My batteries were on backorder and took awhile to get. The install went smooth and the cart runs great. I did something very similar to your charging setup, but I used the factory pin handle instead of the Anderson. Anyway, just wanted to say thanks for the helpful video. Happy hunting!
Did you or when are you doing the range test with new batteries????
I did a test on pavement and got 24.7 miles with 25% battery capacity left. I didn’t do a video on that run but do plan on videoing an offroad range test at the farm in the next couple weeks. Stay tuned.
