Because this is only a battery. You need inverter and more parts to make it like an EcoFlow.

Everything runs through this [eco-worthy.com] inverter. It takes up to 500V of solar input and I have 13x410w panels that gets me right up to about 480 or 490V, so I'm at the limit for what I can hook up to this. Peak production I've seen was very briefly ~4.8KW with ~4.4KW being the highest sustained charge rate I have seen so far. The 4S2P battery setup has each bank running to a bus bar and then bus bar to the inverter. It's grid capable as well for those looking to hook into that, but I have no experience with that. I also ditched the included wifi module because it's limited to using a very crappy app that was a huge pain to get set up. Instead I have a Raspberry Pi hooked up via USB running Solar Assistant which was super easy to setup and allows me to monitor the system from anywhere.

Look at the size of the switch and display relative to the size of the battery. There's no way that's 100AH. I've got one that's almost exactly like that, but maybe 1/3 smaller in size. It's labelled capacity is 7AH. The dimensions in the listing are 4 x 4 x 6. Mine is 2.5 x 4 x 6. There's no current battery chemistry that has an energy density that high. They are counting on the fact that, since it's likely shipped from China, you're not going to put up the money to return it (especially since it's a battery and require special handling). They might offer you 50% of your money back, and they still win because that battery is worth about $25.

Is it possible to pair this with an inverter that will output 240v as opposed to 120v? If so can you give me an example of such an inverter?
It looks like this inverter does 240v.

Look at "split phase" inverters.

Quote from DealMongr :
I bought 8 of these in multiple buys at different prices second half of 2025. This price is at or near the best I paid. So far I am very satisfied with them. They work with the Overkill Solar app to provide fine control/monitoring of BMS performance also.
I don't believe the overkill solar app works with these anymore, or at least it didn't work with my battery (this same one) that I purchased about a month ago. I read that they (eco-worthy) recently closed down their BMS to other open-sourced apps.

If there's a way around it, I'm interested Smilie

I'm using two of these in series with an Ecoflow alternator charger and Delta Pro 3 for cheap expansion. Bluetooth on both is absolutely abysmal; immediately failed after a cycle or two, and the only way to bring it back is completely draining each battery until the BMS trips and charging them back up. I'm not doing that every time the Bluetooth disappears. Price is still good though so I'm just using them as dumb batteries.

Its ok when solid state batteries come out these will be way less than $220.

I have a new travel trailer that I'm looking to upgrade to lifepo. How can I tell if I need to upgrade the converter as well in order to fully utilize the lifepo battery (ie this one)
If it's a new trailer, chances are the converter has a switch on it to change it to lithium mode so it will fully charge the batteries. It should say in your manual somewhere.

You never heard of chargebacks? Always use a credit card from overseas shippers

I just measured 0.7A from battery into the inverter. Batteries are fully charged and AC output shut off to isolate any potential battery usage. Sounds about right based on my low effort, occasional power tracking in Solar Assistant. YMMV based on your own setup/configuration though.
Which setting was it to disable AC output do you remember? I'll need to dig through my manual to find that

I bought one of these a few weeks ago for $260.. It is a beast. I hooked it up to a Xantrex Freedom XC2000 inverter with 0 gauge cables and it ran a 1800W hair dryer no problem. You know, not my expected use case, just a test. Smilie
For $235, I had to order another one! Thanks OP!

I just flipped my main breaker. I wasn't really using anything at the time so figured that would be the quickest way to get a measurement. I don't recall if there's an onboard setting to disable it.
