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.

[bradenb]

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.

[markusallport]

Love your teardowns, always educational and informational! Thanks Will.

[davekent]

Love how happy you are when you opened it up it made me happy thank you

[richlandry]

great video, I am a large dealer for them, never had a bad one in yearssss, I use them for solar too, but mostly for EV

[FSUGrad]

If Will taught a class I'd drive to him and take it.

[ricklee]

Don't care if it's long and boring but it's always good to have reliable information and real world testing 👍👍👍

[Ravensmiths]

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

[SandiRose]

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!

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.

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.

[josephamaral]

That brake resistor seems very interesting. Hope you talk more about it in future videos. Was pretty entertaining to watch and would love to see more EV vehicles you may have.

[RicoCantrell]

Damn it man. Now you make me want a golf cart. Awesome explanation on the current draw.

[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 :-)

[robinrapport]

Im down here In quartzite for the first time. I need a cart like that here. It would be much better than the noisy side-by-side that people use.

[dominique___]

I just LOVE how excited you get with simple design surprises. And I really appreciate this video, because I own 2 golf carts. Thanks!

[darthtater]

THIS is what I’ve been wanting to see. I’d love to see more traction batteries. Eco Battery is another popular brand that gets good reviews.

[Isaacmantx]

I am more and more impressed with RoyPow the more they are on the market.

[leroyharder]

Nice battery for a future zero turn and garden tractor conversion. Also have in mind converting my small boat to electric when the old outboard finally dies.
