Good video, that said, whatever happened to the long-term testing of the military-grade flexible solar panel that was mounted to the roof of the golf cart?

[@WillProwse]

@@__WJK__ yeah it's still working. Need to test output during summer. It charges up nicely still. No issues at all. Need to make video on those

[@sokerdy]

Hello would u pls reply me?

[@adjake1]

We have installed a few hundred of these into golf carts. They have gotten a little better over time. The smaller packs are barely good enough really depending on driving conditions ie. Anything with real hills and they can’t handle the inrush current. The one you are installing is their high output. The high outputs so far have been pretty reliable.

[@derrickzeng]

I think you are right. This is because its continuous discharge current is not big enough. Just imagine, with 4 big guys and other things loaded on the golf cart with this battery, driving uphill, it will probably stop working and the meter display remaining power could be up to 25%. And take a look at the connection panels between cells and other joints, it is alluminum alloy, instead of copper, it means that it is not for high working current at all. I have to say, it is beautiful but it is not the best.

[@TheGorf]

Disappointed to see that they are only currently offering the 24v 80Ah units for sale. I'm assuming they are just out of stock. The unit in the video here is what I want for my Cushman truckster.

Will, your videos are so entertaining. I love how even though you're an expert and have been doing this for years, you still get so much joy out of something like your golf cart moving on battery power. I can't imagine you didn't think it would work, so the fact it made you so happy was just awesome.

[@davekent20]

[@joentexas]

I just like watching your technically oriented videos. Your curiosity is infectious. With year-round sunshine, I can see myself building a small portable solar unit to keep the groceries cold in the event of any power outage. Thanks, Will.

[@jalindell]

I did this last winter, built a 1kwh battery pack that can run both fridges in a power outage, its a pretty cheap project, you should do it. 2 100w panels, a battery of your choice, and a solar controller and inverter. If you do it on a hand truck there are quite a few videos on making a quick and easy one using integrated Controller/inverters and a rackmount battery (5kwh). Just be sure to use a 20amp power strip when you wire up AC.

[@Ravensmiths6]

I love how excited Will gets about the little things 👍😀

[@SandiRose2008]

I love it when you love it! You're like a kid in a toy store. It's great when a product is made so well!! Thank you for the video!

[@AussieInSeattle]

nice. I've been running the same battery (105aH) in my cart since may of 2021 with no issues. I turned regen off via my alltrax controller so don't use the resistor. I still get 3-4 rounds of golf out of the pack. Also just installed a 48 volt forced air heater and doors for winter golfing :-)

[@richlandry8820]

Would like a price. It's not available on the purchase link.

[@TwotheHorizonSailing]

Hey there, do you know why RoyPow is saying the 160p 48v golf cart battery can’t be wired in parallel?

[@paulmccoy2908]

I bought some “Sapphion U-Charge” LiFePo4 batteries for my Polaris Ranger EV about 8-years ago. It was 4x12v cells instead of the 8x6v stock set up, and just required reprogramming of the original onboard charger and purchasing a very expensive “CAN-bus” solenoid. They look exactly like deep cycle batteries. I’m still getting 35-40 miles per charge compared to the 45-50 miles when they were new. The lead-acid batteries were weak by the time I got it but they were supposed to be good for 45-miles on flat ground when fresh (it was down to 4 or 5). Best purchase I’ve ever made for that thing.

That's the nice thing about the golf carts. My mom has used one for years, out in the desert (rock hound). Air down the tires (if you're in sand), and go. Unfortunately, it still is limited to where you can go, but still wonderful to have just to cruise around quietly.

[@JStarke240]

I went with Raw EVE LF280K and a 250A (which easily exceeds 300A for a bit of time if needed) smart bms. A bit of modding of the battery tray to create flat platform for the pack and a compression setup with water proofed ply and some threaded rods/locking nuts. It has much more range and capable of higher amp draws without going much if any beyond 1C, and it's been working great for months now. I've got so much range I only need to recharge once every 2 or so months, and I've connected a PSW 3kw inverter to power fridges and freezers during power outages. As far as bang for buck goes, there isn't a better option (if you have a bit of time and some tools to do the work, which only requires homeowner stuff).

[@Ryan-uk8ni]

You are the only other person who I have seen do this. I built one out of 280k cells as well. 24s. It barely fit. I used the jk bms, and I've seen burst of over 370 amps on the app. You have any photos of your setup?

[@chrisdelahunt5844]

I purchased a 48 Volt 100 amp LifePO4 Battery for to replace lead acid battery pack on a EZGO golf cart. I work fine until i went up a small hill. It then stopped and the battery switched off. I contacted the supplier and they said it was the BMS was not up to the job . They refused to reimburse me and i now stuck with it. Can you recommend a suitable BMS replacement? thanks

[@Hobbies4Hire]

Great job on the video Will! Thanks for making it. You mentioned Surron, any chance you might pick one up to showcase on the channel? I am really into the idea because with dirt bikes, the barrier of entry that is maintenance and upgrades prevents a lot of us from pulling the trigger. With electric, there isn't really any maintenance and they're so easy to customize that it really makes it a lot easier to et into the hobby. Someday I hope to buy one and paint it to match my 4runner and get a hitch-mounted bike carrier so that when we go off-roading, my wife can drive (she's a better off-road driver than I am since she pretty much does it for a living) and I can zip around her on the bike to get some rad video footage. If you're thinking about it, there is another Vegas KZbinr called Vegas RoManiac you might want to reach out to. He rigged his to carry double the batteries than a standard model so it gets a tone of range. The aftermarket is insane on them too, with tons of higher power or higher capacity batteries along with all the standard upgrades you can do to a dirt bike. Thanks again for making this video!

First I want to say thank you for all the information you share I've learned a lot from your videos and I've come to trust your opinion on a lot of issues surrounding solor power, so I would like to ask your opinion on my plan so you know because of injury's I cant work anymore and I waited to long to try and get social security disability insurance, who knew you'd get screwed by holding off as long as possible before applying for it and so I was denied and ended up only getting SSI which pays less then a thousand a month lol so it's challenging to say the least to afford much for anything I have to move out to my property in Kentucky or lose it and its undeveloped I'm going off-grid and I can't afford to do the normal kind of solor system that most people do , my plan is to do small systems for individual areas of my home and other need such as one system for my bedroom and living room and a separate for my kitchen and bathroom and another for my water pump etc.. so I can build each according to separate needs and if something fails like say my well pump I can barrow say my bedroom power till I can fix the well pump system and I don't lose all my power because I can't afford a new part right away . In a way it's like I'll have a back up if needed it will be priority that decides where the power is supplied. So please any advice would be appreciated if you find some time. Thank you I forgot to add that I'm planning almost every thing I can to be 12v since it's only small systems although I may do 24v for kitchen so I can run a refrigerator or freezer. And we don't watch TV we only use our cell phones / laptop for that

I had the same problem with Powerpoles several melted with only 6amps going through them, I gave up on them and I use EC5 (120amps) and EC8's (250 amps) they are much better IMO for making solid connections, you do need to solder them though and an EC8 takes a powerful iron to melt enough solder for the wire/connector

🙏🏻 Any recommendations for me to look into? I have been thinking about something like this for my project use. A 48-volt 100 ah golf cart battery is perfect size and is built rugged enough for what i'm building. Want to combine it with something like the EG4 3000, all in one solar and inverter system. I am building myself a nice small custom hot dog cart trailer. Would like it to run off grid for at least 10 hrs, like a rare maximum of 16hrs. It's running a small refrigerator, which is something like 160w ish @ 120v and a bunch of led light strips at night for 6 hrs of advertising backlighting. I would also like to incorporate a DC to DC charger of some sort, to connect when in transit, and be charged off of the towing vehicle somehow. I'm not sure what I would need look for, for solar panels, but it would have to be something like your golf cart here, as I really don't want them much bigger than the cart footprint itself which is like 42"×72" or so. I know I will have to get a 12V DC converter for some components, like a small water pump. Everything is going to be on a remotely located panel for monitoring and switching, as well. Any of your recommendations to look into would be very much appreciated, Thank's
