These just get cheaper and cheaper. I have 3 of these, two in a truck camper and one in an enclosed trailer. I really like them.

$75/kWh...that's getting cheap.
Can you string these together in Series to get 48v?

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 over a month, 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.

Unrelated to Ecoflow, but yes to AliExpress - I'm dealing with an item not being delivered that some random 'last mile delivery' provide caled PIggy Express says they came at 6pm on Sunday says delivered. On the comment of the battery not fitting, I can see them saying 'should have measured' as its not cheap to ship these batteries...

Yes. But you need a good balancer to keep them at the same voltage.

I ordered one of these from EcoWorthy via AliExpress. Arrived just fine and worked great for nearly 75 days. Then the Bluetooth BMS stopped responding and can't connect via the app. Tried three different iPhones with same negative result. Forums suggest running the battery down until low voltage disconnect occurs then recharge. Tried that a few times with no luck. Opened a support ticket with EcoWorthy. They are quick to try and close your support tickets to keep those SLAs in check. Followed their instructions which also requested draining to low voltage cutoff. Took me about 10 days of back and forth troubleshooting. In the end, Support told me because I had the item for more than 90 days that AliExpress limited their return options. They did offer a decent credit towards any Aliexpress EcoWorthy purchase if I would keep the battery instead of returning. I haven't used the credit yet so I'm unsure how much of a hassle this process will be. Loss of Bluetooth BMS connectivity on this 12V 280ah model does seem to be an issue. There's a decent amount of online posts about it so be aware. I'm still happy with the battery. Runs a 12v fridge for me for a 10-14 days. Keeps my beverages cool and I avoid paying convenience store prices.
