Bro - this is a 12 volt and this really is for powering electronics in a Van or Bus build - this is a lot of ah! Not meant for starting a vehicle though you could overkill with a golfcart

This question is kinda like buying gas and then asking what car to buy with it.

Honestly, it's going to depend on what your needs are and how many watts you need. The less watts the cheaper it's going to be. Also it will depend on how much you want to spend, reputation of the brand, etc. if you can figure out your watt consumption you can then find the best option for you.

Pretty sure they mean buying 3-4 for an electric golf cart (depending on 36 or 48v application).

Why does anyone even use 12v anymore? You get much more bang for your buck at 48v.

What is 48v useful for?

Chinese sellers are having a problem with supply as tariffs have suddenly shocked factories. They'll offload at lower prices with less profit to lower warehousing but that'll only lead to higher prices looking at stuff one to two years from now. Don't expect large price fluctuations in the near-term.

more watts for the same gauge wire. look up how big wire would need to be for just a 12v 2000watt load.

Depends on the use case... It's almost 8 times more expensive for a couple improvements that aren't really needed for me...

I don't need 300a discharge for my RV, 200a is fine. I don't need IP68 waterproofing, and I don't need a heater.

I have an older RV, my battery is located inside and my RV is currently set up for only basic loads when running 12v.

That being said, 4 of these ecoworthy in parallel would be a much better value, it would give me 1200 AH of capacity and up to 800A discharge (if I did ever want to run larger loads.

Sure, the one you linked is great for someone who will be charging/using in below freezing conditions and where exposure to the elements is a concern, but that's not necessary for the majority of RV use.

Exeltech - are the most reliable inverters available. Bullet proof and abusable. When it has to work, you get one of these. Made in the USA. 1100 Watt True Sine Wave Inverters: Low Distortion Protective Features (exeltech.com) - They are not cheap but inverters from china are trash power quality and break. For a Slickdeal, watch ebay. That is what I did. Paid $400 used for it, and it's runs fridge/deep freezer off the Prius when the power is out.
