I've got a set of 4 of these batteries for my home battery backup solution. No issues with the brand on the model, preferred a metal solution for stacking and organization purposes. I paid about $330 maybe 2 years ago, so this is a new low price from what I can tell. May add a few more eventually.

Thank you for this.I have a club car precedent (2018). It is the 6x8 arrangement you first mentioned. Cart gets light neighborhood use, so I can probably get another year out of the batteries. But likely will need replacements sooner rather than later.
You'll get a lot more performance with this battery than the typical. Fraction of the weight.

Apologies for the ignorant question, but is this saying that basically only one of these can replace my entire series of golf cart batteries? (currently have a 48v club car precedent if that helps).
I looked at this battery for my 48v golf cart. The golf cart pulls 2
300-400a on hills. This battery is 50a continuous and 200a peak- meaning it will probably not work well for a golf cart.

I suspect it's a different kind of peak value. Some items require quite a bit of amperage at start up that trips up some inverters and BMS (items like the compressor on a fridge, an air compressor, saw, anything basically with a motor built in). It's for a very small fraction of a second at start up. That's the kind of peak they are talking about. That's golf cart is pulling that kind of juice for an extended period of time by comparison and would trip the protection circuit almost immediately to protect itself.

Looks like a good utility-use battery where you don't need monitoring.

You can throw these and pair it with most solar inverters or off grid inverters compatible with 48v. Cant use it in you car with typical 12v inverters though. use case would be a shed or something outside that doesnt have a power line ran to it.
Today I learned that there are 48VDC to 120VAC inverters.

Which is a pity - I have a really good 12VDC inverter, but I'd have to get a new inverter for this battery.

I am currently dealing with EcoWorthy through AliExpress, and this has been, without question, the worst customer service experience I have had in over 50 years. What should have been a simple return has turned into an ongoing, frustrating ordeal. The batteries I purchased do not fit, yet after more than a week, I am still being given the runaround with no resolution in sight. The level of inefficiency, lack of accountability, and overall disregard for the customer is frankly unacceptable. Based on this experience, I strongly caution anyone considering a purchase to think twice. I would not consider buying from this seller again under any circumstances.
