Not a bad deal for a 280AH that has a Bluetooth BMS and a 20A charger. Eco-worthy cells are built (internally) much better than most others. I'm referring to its internal metal frame and fiber board structure to compress the cells… where as everyone else just tapes their cells together. This is coming from someone who builds LFP battery systems and have taken apart my fair share of eco-worthy batteries. The cells they use are good and true to quality, but they're no EVE280K (and the price reflects it).

How many of these can you put together?

16 of these can be wired in a 4P4S configuration and will give you a net of 1120ah @ 48v (51.2v nominal). This configuration will give you a total of 53.76kWh. This is a substantial amount of energy.

What cells do they use?

Ordered similar combo deal about 10 days ago, battery came in 5 days, but got a note that the charger was out of stock and I'd have to wait a little bit. I'm sure I'll get it eventually but I haven't gotten any updates on when that will be.

How do you use this energy? How do you charge house and or appliances with this setup?

Is this Lithium iron phosphate battery or just a Lithum-ron battery?
Also need to buy a separate inverter?

This is a lipo battery(lithium phosphate), the included charger just charges the battery, to use the battery would depend on your intended use case. You could connect 1 12v battery to a car inverter that does 12v dc to 120v AC, you could buy a solar inverter that does solar to DC to 120v AC, or if you had a 12v DC load like a light you could run it off of the battery

What I described is just simply multiple batteries wired together to act as 1 larger higher capacity and voltage battery. When it comes to how to use this power,.. there is no short answer but I'll try my best to simplify. Once you have a way to store energy, you need a way to use it. This is where inverters come in play. inverters convert battery power or direct current (DC) into alternating current (AC) which is what a household circuit provides. They come in many different sizes but for reference, a single standard 15 amp household circuit can provide approx 1800 watts of power so get the size inverter according to how much power you need. So when the battery is drained. You'll need a way to recharge. This can be done a few different ways. A couple common ways is a standard AC to DC battery charger or a solar system that utilizes solar panels and a solar charge controller to charge the batteries. Theres always going to be different ways to do the same thing, and I could spend hours going in depth about all the different ways one can use a battery but I'd recommend using youtube to help educate yourself on this stuff. One guy in particular that I'd recommend watching is Will Prowse. He really knows his stuff and he breaks things down to where its easily digestible to the average person. I learned a lot myself from watching him. Good luck

No, thats entirely wrong. LiPo Li(Lithium), Po(polymer) batteries refer to Lithium-Polymer. this is LiFePo4 which is Lithium(Li),Iron(Fe)Phosphate(PO4) The names themselves are both literally made up of the elements and chemistry of the pertaining battery. Nearly everything you said is incorrect. A light isnt a dc load. its just a load. They can be made to run on DC or AC. the ones in your house are most likely AC powered and the lights in your car are likely all DC powered bulbs. I don't even have time to get ito everything else that you said thats incorrect which is basically every,... single,... thing, you said. Good lord I dont think I've ever seen so much incorrect information packed into such a small paragraph in my entire life.

So he could buy a solar inverter that does solar to DC to 120v AC?

What in the world is a solar inverter? You say its something that does solar to DC to 120v AC? No. that doesn't even make any sense. Solar or PV (photovoltiac) electricity is DC so it doesn't need to be converted to DC It's just unregulated DC that fluctuates up and down to much for it to be useful or safe to use yet. This where a solar charge controller comes into play. a SCC takes all that fluctuating up and down DC voltage and amperage you get from directly from the sun and regulates it to a steady correct voltage & current that can be then safely and effectively used to chargte a battery. Finally it then goes from the battery to an inverter to be turned into a nice useful 120v AC. You have zero idea of what your talking about and what your saying makes no sense. Please stop trying to help people. This kinda stuff can be dangerous to play with if you don't know what you're doing.

Newbie question: Is it OK to use a 12.8v battery, like this one, to power RV items that are 12v?

It's not only OK, it's an excellent choice, probably the very best choice to power 12v RV items. It's superior in every facet to AGM batteries for that purpose. The only advantage an SLA/AGM battery has over this type of battery is it can be safely used as a starter battery. Other than that, SLA/AGM batteries fall short in every other facet by comparison.

Wiring up batteries in series is never actually recommended though.
Yes, it's a real thing.
Yes, millions of people do it.
But it's fraught with issues and annoyances.
Plus, by the time you add in all the REQUIRED fuses and cables for a 12V 4S4P 48V battery bank you're talking about literally multiple hundreds of extra dollars to connect all that up.
It isn't worth "saving money" by buying a few of these at a time and slowly adding them together in some sort of Frankenstein amalgamation.
It will always be easier and less money in the long run to just buy the voltage battery you intend on using.

Series connecting a few of them together to get to 24V or paralleling a few to increase the AmpHours is usually fine.
But recommending people connect 16 batteries together is wild.
