Man this is getting to the price point that's awesome.
EDIT: Oh only one per order? Can you order multiple times with code?

That's roughly 7x the capacity of a typical e-bike battery, with the right voltage. (I wonder if it is 48v nominal and about 55v at full charge like a LiPo "48v" battery or it's 48v max -- but either could be worked with.)

Standard discharge = 50A, so that's good too.

If I had a big cargo e-bike or a e-trike with a good place to put this 100 lb battery I'd be very inclined to give that a try (maybe mounting it on a foam pad to reduce vibration and make sure it's all waterproof)
-- even with the extra weight, this has enough capacity that it should give 150+ miles of range and yet costs only a little more than the standard batteries.

Fantastic deal. Not in the market for one yet but the rate they keep dropping is crazy. We're close to $100 per kwh it seems

So your use case is to strap it on an ebike? Honestly just curious. Looking for something for backup power to my network rack with my NAS, etc

Odd, these ship from SoCal, tariffs already paid. If you used PayPal it may be the cash advance surcharge everyone complains about.

Aliexpress uses funny terminology. For me the "additional charges" were just my state sales tax.

Snagged one, this is a pretty good price.

Just be careful if you are obtaining them over time and want them to match - there are many different versions of this battery as they have made steady improvements on it, however they keep the model number the same which makes things confusing. There is another version they are selling that says cubix 100 in the lower right - not sure the difference.

I would not use this for back up power to the nas. No mention of sin wave or how fast it switched to battery power when the power is cut off. I would stick to a traditional backup unit specifically designed for computers and servers to run on.
This will not provide backup power. Its just a battery. No inverter or AC outlet. It does have communication to most solar inverter brands for charging rates and state of charge information. Can you strap it into an Ebike? Probably can but this thing is heavy and wide so cant really mount it well. Probably can be used on a golf cart.

Its LFP and 48v is nominal and approx 55v is full charge. Has Bluetooth so you can monitor the state of charge and battery health on your phone. Not sure if it can handle the constant bump on an E-trike or golf carts. Youtube shows these batteries are assembled quite well.

Please don't comment on stuff you have no idea what it's. This is not an inverter or automatic transfer switch. This is just battery!!!You must pair this with an inverter, ATS, and make sure it's pure sine wave depending on your use case.

It's the use case that comes to mind -- all of my UPSs are twelve-cell (so 24v nominal) lead acid, so I can't use this as-is.

But rack mounting it and either having it power equipment directly (if it runs off of 48-55 v DC) or serve as the battery for a UPS (make sure it's the right chemistry and voltage!) is arguably what it's really meant for.
