I bought it with the idea of adding another if it did not suit my purposes.
One of the graphics in the ebay listing shows 200A peak discharge.

From my research for my purposes:
The stock 48V motor in a 2008 Club Car DS typically has a power rating of around 3.2 HP (horsepower), which converts to approximately 2,385 watts (since 1 HP = 746 watts).
To calculate the amps at 48V, use the power formula:
Power(W)=Voltage(V)×Current(A)
For a stock 48V, 3.2 HP (≈ 2385W) Club Car DS motor:
2385W=48V×Current(A)
Current=2385W48V≈49.7A
So the motor itself at full throttle is right at the limit of the advertised sustained output of 50A.
The motor startup and driving on hills can exceed that power draw.
So suitability depends on
1. whether the battery can exceed the 50 sustained A draw
2. by how much
3. for how long
4. what the efficiency and current requirements are of the controller and other components on the cart
4. whether your driving patterns and needs are met
1,2,3 depend on the quality of the cells and the built in BMS.
From a graphic in their Amazon ad they show a golf cart with a single battery with a range of 20-28 miles on a single charge. Another graphic shows 200 A peak and grade A cells. There were lots of batteries with a cell/BMS combo that seems to support 100 A peak and 1C peak current.
"ECO-WORTHY 48V 50Ah lithium batteries allows to maintain 2~3C peak current for up to 10 second, 50A maximum sustainable discharge, 48V 50Ah Lithium Iron Phosphate battery can support a 5.4 hp (4,000W) golf cart for approximately 28 miles on a full charge"
I THINK that if you exceeded capacity driving up a long hill with over the limit sustained usage the failure mode would likely be tripping the BMS protection (which would later reset) not slowing down. (assuming they chose a good BMS and settings that would protect the battery appropriately )
Conclusion: When I decided to try one of these I based it on the advertised specs and advertised suitability combined with my expected usage pattern. I have not been disappointed, performance and range are good for my use case. I have another almost identical cart (few serial numbers off) with a 100Ah battery pack by a different manufacturer and their speed and acceleration are not noticably different. I am not using the cart for two rounds of 18 holes of golf otherwise it might not work well.
Disclaimer: your situation will be different, there may be variations on battery quality or BMS settings between the same model of battery. You may find you need two of these batteries for your specific cart (or non-stock controller) to meet your current and range requirements.
Yeah These Lifepo4 battery can usually sustain much more than their rated outputs.
Most all of 12v 100ah Lifepo4 have a 100a outputs and in testing, they can sustain much ore than that.
I don't doubt this battery can sustain more than 50a.

If u really want a laugh, go to google and type this in:
50 years of failed climate predictions
They sound pretty credible. Where did you see that frozen land is expanding?
[edit: nevermind, I see you shared one above AND the pricing AND the fact that you bought one]
BTW, this one is ADVERTISED as being usable for golf carts and I shared real world experience that it is working for me.
Funny thing with no planning I performed an almost ideal test. I got two non working 2008 club cars last november. They were just a few serial numbers apart. I planned to fix both and sell one to cover the total cost of carts and fixes. I figured one I would go higher end on the new components and upgrades (including DC house 100Ah battery) and the one to sell I would look for economical components (eco-worthy 50Ah). After some other replacement parts, key switches for both solenoid and controller for one. Both are running great. We are currently driving the one with the 50Ah but will swap later.
In my experience both the acceleration and top speed are about the same at with 1 or 2 people riding. As expected the 50Ah voltage lowers with fewer hours than the 100Ah. If I had more time and better weather I would do some more testing to failure as well and put together a video worthy of Project Farm.
Side note: some where along the line I read that eco-worthy and dchouse are related companies. I have not bothered to confirm

Then click on a few of any of the links that pop up and start scrolling. The only shocking thing for me is that google allows them to appear (so far). You do realize they are about as trustworthy as big pharma, cia, politico, your nightly news, etc....
