Haha, I already bought 4 of these.
By far the cheaper Lifepo4 ever. Less than .10 per wh.
Rated at 1920wh and I've tested 2 of them and got 1950wh.
Was going to post this but it seems I always get deleted everytime I post a deal.
These are not cranking batteries, they are designed to supply current at a somewhat steady rate. You would not want to use these type of batteries as your starting battery.
Description says 120A max continuous discharge x nominal 51.2v for your x4 series, so I come up with 6144w max output.

Working back from you numbers, it appears you might have been multiplying 12vx150ahx4 batteries to get that number and were referring to capacity?

In that case, multiply the 150ah x nominal 12.8v x 4 batteries for 7680w/h. Then multiply by inverter efficiency (check inverter, but 80% is conservative in most cases) to get usable capacity, which in this example would be 6144w/h

I bought this charger and it charged up my LifePo4 battery fine. You can youtube reviews on this type of charger. It is slower, but works as well as more expensive and has other functions for other type of batteries.

Looks like these are made for a battery bank, meant to be used with multiple other batteries and a system, since there is no BMS and does not look as durable as the deal posted, plus no bluetooth control (due to no BMS)

Because that is a single cell. Requires multiple cells, bus bars, BMS, case etc. as well as the knowledge and skills needed to build it to match the functionality of this EW battery.

DIY batteries can be great if you know what you're doing, and understand the pros/cons. Definitely not a plug and play solution like we're discussing.

This is a 3.2v single cell, the Ecoworthy battery is 12.8v made up of four 3.2v cells plus a battery management system (BMS). You would need 4 of the 3.2v cells in series to make 12.8v. As others mentioned, you'd need a BMS to safely use the cells, and all the metal connections between them, plus the time, effort, and money involved with it all. It's a bit like comparing a CPU to a whole computer.

Just got this message from the seller, seems sort of bait/switchy:

Hi ,
Sorry to bother you. Firstly thank you for purchasing our 150ah plastic cased bluetooth batteries,
but we are sorry that due to the current stock shortage they are not available to ship at the moment,
but another metal cased 150ah battery is in stock.
Maybe you are ok with us sending the metal cased 150ah batteries?
They are about the same size as the plastic model batteries and have the same bluetooth function.
Looking forward to hearing from you.

Best wishes, Oliver

Yes. Don't run the trolling motor at max speed to prevent from burning up the motor

So stupid question, if I got this to use for my CPAP (I have a 300w inverter to use 120v, or could buy a 12 cable for better efficiency), could I use a 1.5 amp trickle charger I have (made for lithium batteries) to keep it charged?Basically I would keep the trickle charger plugged in 24/7, and run off the battery every night for 5-7 hours a night. Lately we have had a lot of power flickers in the night and it resets my machine and wakes me up. I want something that will always be on regardless.From what I have been able to find, my machine with heater on is like 20 amp hours a night, I rarely use my heater, so probably closer to 5 amp hours.Would a 1.5 amp battery tender be able to keep this thing charged?By my non battery smarts math, I would be putting in a max of 36 amps a day, while using 20 amps a night. Is that correct or is there more to it?Or would I just be better served getting something like this RIver 2 for the same price (which from what I have read, can do 6-8 hours of non-heated cpap use?https://www.amazon.com/dp/B0B8MXPRDB/I am in the process of getting a whole house manual generator backup (waiting on deliver of generator that is on backorder), so long term use is not a big issue.
I got the River 2 a week ago and it has allowed me to use a Cpap non heated for 7 hours a night for 3 nights...it drop about 30% a night using a DC cable. (testing). I think I want the 296wh one to be safe

I got that message too but it didn't mention the metal cased ones having Bluetooth. I don't see a Bluetooth 150Ah metal cased battery in their listings. He also said they were coming in next week, i.e. not in stock. You'd think the messages would be the same (cut & paste).

Edit: Oliver just responded and sent an image of the case with the Bluetooth symbol.

So it looks like the 20% off only applies to one battery when I have 3 in the cart. Anyone know if the discount can be applied 3 times if I purchase them 1 at a time? Any other alternatives to achieve the discount for all 3?
