I am trying to buy American.

My advice is don't get too caught up in finding a U.S. manufacturer.

The first one on your list is made in China, not Florida.

I've used three different brands of lithium batteries: Evolution, Dakota, and currently Vatrer. The Vatrer is a very well-made battery, and I highly recommend it. You can buy directly from them or through their Amazon store.

Trojan is a full 5 year replacement and an additional 5 years pro rated credit so 10 years total and another reason I went with their lithium when comparing to other brands. I have heard many others are starting to offer 10 year warranties now.

That's the same warranty as skunkworks. 5-year full then 5 years prorated. Everybody has their own opinion and I understand that. I have worked with this guy I don't think there's anybody that Trojan that would reach out and work with me the way this guy has. Like I said it's just my opinion, I think they're the best. And if you're on any of the golf cart forums, just search skunkworks see the responses

I can call Trojan direct about the warranty that is in my name. Trojan has been around for a while and you never know about the local shops they can tend to change hands. If I get a warranty from a local shop I would be concerned if the actual battery warranty is in my name or the local shops? It would be worth asking who is standing by the warranty, the shop or the manufacturer or both?

What model batteries did you get and what cart did you put two batteries in?

[revfiddle]

I used Battery Bros. Decent price, good warranty. I don't need a lot or range. 40 miles is plenty.

Installed 2 of the DIGI CS-Plus 48V 100Ah Golf Cart Lithium Battery in Parallel mode. Total price delivered $2,198.00 from Building an Integrated Closed-loop Energy Circle Via Intelligent Syste
– DIGI MARKER These batteries have CAN Communication Parallel Support and Burst Power: 400A/30s and 1000A/3s peak current, Built-in Premium 12V Converter, replacing old trojan lead acid ones.
I installed in a 2021 Yamaha PTV PowerTech 2-seater with 600AMP Navitas Controller. First test (5-2-2026): Deluna Neighborhood Poker run, 45 miles running about 24MPH, had 53% remaining when we got back.
I’m happy with the dollar per amp hour and range. I realize these may not be for everyone, being the DYI route. But do agree with the post above, 99% of these LiFe4PO4 /prismatic cells all come from China with companies here assembling and combining with differnet BMS's.

Well, that's where I'm at lol. Still haven't made a decision.

I have previously spoken to most of those battery manufacturers (importers is more correct) at trade shows.

Of those listed only one is "made in the USA" (Skunkworks) and they're actually just assembled in the USA using Chinese parts. Look at the manufacturers warranty and how long their "battery" label has been in business, because personally, I can care less about how long they have been putting electric motors in VW bugs... By the way, I've hand built at least a dozen custom lithium cart batteries and have been following the topic closely for the past 7 years.

Currently, I recommend either Bolt or ECO and I'm lean towards Bolt if it fits due to warranty and fewer "software update" type of issues, but ECO has more size options. As for cost, a reputable dealer should offer FREE installation if they are charging full retail price, ( also most of the manufacturers are requiring sales prices be fixed at the MSRP) for a complete kit including battery, brackets, charger, meter, cables. Look online at ECO and Bolts website and check the MSRP and that's about what you should pay installed.

Also I think that Battery Boys and Battery Brothers, while convenient, are not to be trusted. I've seen them charge over $4,000 for a cheap $900 no-name Amazon battery, then not provide warranty service for it.

Try Bo's Buggies, he is a local family run business who is affordable and reliable. Last time I checked he offered free installation.

Be careful what you believe about the range of battery powered golf carts. The rule is about 6 to 7 miles per kWh of battery energy. So for a 48 volt system a 105 Ah battery has 5 kWh of energy which is good for about 33 miles. If you bought the 72 volt Bolt lithium battery that would take you about 50 miles - nowhere near 85 miles. That is the physics - don't rely too heavily on the "% charge left" as it is not necessarily a linear function and you do not want to go below ~ 20% regularly as that will shorten battery life of some systems.

That's not correct.

What is true is that Trojan Battery is an American company, but the OnePack lithium system uses globally sourced lithium components and cells, as is common throughout the lithium battery industry.

A lot of people focus only on where the lithium cells come from, but that is only one piece of the equation. The reality is that nearly every lithium battery company in the golf cart industry sources at least some components globally. What matters more is who engineers the complete system, who performs the testing, who provides long term support, and whether the product has legitimate third party certifications.

That is where the Trojan OnePack separates itself from many of the smaller brands and random online batteries. Trojan Battery has been building batteries for roughly 100 years and has one of the strongest reputations in the golf cart industry. Their lithium systems are designed specifically for golf cart applications, not just repurposed generic lithium packs with a golf cart sticker on them.

The UL certifications and ISO certified manufacturing processes are a much bigger deal than many people realize. UL certification means the battery system has gone through independent third party safety testing for things like thermal protection, electrical faults, battery management systems, wiring protection, and safe operation. ISO certification means the company operates under documented quality control and manufacturing standards instead of just assembling batteries in a warehouse with little oversight.

That becomes extremely important with lithium because a poorly designed or poorly protected battery system can become a serious safety issue. A lot of the cheaper batteries online may advertise huge amp hour numbers and low prices, but many have limited testing, questionable warranty support, and little long term track record. Several people in this thread even mentioned staying away from Amazon batteries because of reliability and safety concerns, and honestly that is smart advice.

The OnePack also has advantages beyond certifications. It is a true integrated conversion system with an advanced BMS, redundant safety protections, Bluetooth monitoring, nationwide dealer support, and a long warranty backed by a company that is likely going to still be around ten years from now. Trojan specifically markets the system as designed and assembled in the USA with dedicated technical support.

At the end of the day, anybody can import lithium cells. The difference is the engineering, testing, support network, and accountability behind the finished product. That is what you are really paying for with a premium battery system.

I had Cart World In Lady Lake install my 105 AH OnePack a year ago and it has operated flawlessly. In my Precident, I go about 29 mph and have a range of about 45 miles.

I would go with Master's Golf Carts in Summerfield. They are installing Bolt batteries at present. We have been most impressed by their knowledge and service.
