Complex answer. Short answer is no, you can't really fully charge these without a separate charge controller. With something like a Delta 2, technically you can pull power out of 1 or 2 or even 3 or 4 of these, although it'll be limited to 15A or about 200W if you use just one 12V battery. Charging wise, Ecoflow's 12V output isn't enough voltage to fully charge an LFP.

If you want to be able to charge & reverse charge one of these, at higher rates, with something like a Delta 2, Ecoflow's alternator charger can charge/reverse charge at up to 800W. It's pricy though - I only have one because someone posted it here on Slickdeals @ $240.

Alternatively, without an Ecoflow unit... you can use basically any solar charge controller to charge these things - e.g. this Victron 100V/20A [amazon.com] - which is what I've used with my XZNY 12V/100Ah LFPs. It supports up to 48V battery systems, and it also has load lugs that let you monitor power output historically - really nice little unit. There's also a similar/smaller 75/15, but it doesn't support 48V bats.

Hope this helps.

I picked up a refurbished 100AH a while ago, it tested around 107AH.
Also picked up a pair of 24V 100AH batteries, about 2 months apart. I tested on at 103AH.
Decent batteries.

You would need something like a MPPT to charge the battery using solar panels. It is not plug and play like a power station.

Silly question, this can be charged with a solar panel setup? Like I plug directly into my Ecoflows, no middle man charger. Or would a LiPo charger be needed?

victron is the mercedes of this space.
you can find ali express mppt chargers which can handle 12-24-48v lfp batteries. I have an 100A @ 48v one that was ~26$ with tax on sale, the "EOEXBY MPPT Solar Charge Controller100A" but I did not finish the rest of the setup yet. They can do dusk to dawn (or always on ) 20W or so usb output power ​also, while there is not a full power offering from battery otherwise. That would be fine for some usb powered landscape lighting.
mppt becoming that cheap I stayed away from the cheaper PWM chargers, while I dont know have much of real experience.

You need a solar charge controller that has a lithium setting

Following up questions if you don't mind: if I use 4 of these batteries, would I be able to pull 800W out of them with the EcoFlow alternator charger into the Delta?

Or buying one 12V 280A battery is easier?

I'm not sure why this was downvoted. I have a (dead) marine battery attached to a backup 12v sump pump and I'm interested in knowing if a LiFePO4 battery is a better option than a new marine battery? The use case would be: full charge in standby for (hopefully) years, followed by a deep discharge during a power outage, then return to full charge standby. Few cycles but long shelf life.

You'd have to run them 2s/2p for 24V, or in 4p / 12V; EF's alternator charger only supports 12-24V (up to 30V).

That said, 800W should be no problem with either setup. Wires will get a bit warm at ~13V/60A but it can handle it. FWIW, I ended up shortening the OEM wires to reduce voltage drop because the factory wires are really long for anything besides installation in a vehicle.

bottom of the barrel battery, doesn't even have working short circuit protection...
That is pretty alarming but with the price and the ability to add a fuse/breaker to each hot conductor, still seems like a good deal. You just need to know that limitation as having a dead short with these would be dangerous.

Edit:
A quick search for reviews and I don't see where you are getting your information from. Do you have a source?

you need to know how many horsepower or watts your pump needs. 1HP is roughly 750 Watts.
