off grid solar, house batteries for rv, camper, boat. If you've got 12 V devices you can run that directly from the battery without any inverter which is nice.
I have a power station but its internal battery is a 48 V, so when I run 12 V things you lose some efficiency stepping it down to 12 V. I also have a 12 V battery and I'll just often run those device devices directly from the battery and I get much more run time per ah of battery.

Lol. These were NEVER $1,055. These "sale" prices are ridiculous. Like it's still a good deal. I bought two of these at ~$300 each last year and love them, but please they need to stop saying they're marking it down 75%!

No. These are NOT starter batteries. That isn't how it works.

Community Reviews

This 12V 280Ah LiFePO4 battery is being used as a compact power storage pack for RVs, campers, boats, trailers, and off grid solar setups. It stands out for deep usable capacity, lighter weight than lead acid, Bluetooth monitoring, and enough output for things like trolling motors, fridge backup, and even running an air conditioner for hours in larger banks. The main cautions are that it is not a car starter battery, charging and inverter setups need the right lithium compatible gear, and some buyers flagged seller trust and coupon issues. A strong fit for 12V storage projects that need real runtime.

  • The battery can run 12V devices directly without an inverter, which can improve efficiency versus stepping down from a higher-voltage power station.

    LeakyAneurism

  • The battery can support real off-grid and RV use cases, including running an air conditioner for about eight hours with two units in a trailer.

    proudfoot

  • The battery can work well in a boat setup and has been used for marine power storage without reported issues.

    TheNetGuy

  • The battery can integrate into solar and EcoFlow systems using XT60i inputs, including setups charged from solar through a charge controller.

    DealMongr

  • The battery is not intended for vehicle cranking, and it lacks the amperage needed for starting applications.

    mblitchyourinsuranceguy

  • Charging performance can be limited by connector choice and charger compatibility, since XT60 can cap input around 8A while XT60i can allow higher charging current.

    blupupherimdealing

  • Promo codes and checkout discounts can be unreliable, including cases where codes do nothing at checkout or stop working after expiration.

    pootie22paul2112cx1

  • Bluetooth functionality can fail and may also affect state-of-charge reporting with an AC-to-DC controller, which can require returning the unit.

Be cautious of this seller, as it might be a fake. While the battery is great, this seller might be a scam.
I ordered two on Friday, just received the tracking yesterday and it started moving today. Ships via Fedex from NJ. Weight shows 65lbs which is in line with the other batteries I ordered from them.
I've ordered maybe a dozen things from Eco-Worthy, they all ship from random warehouses across the country.

Can I place 4 separate orders and use the coupon each time?

@gabe23111 or anyone else
Yes, I posted earlier that I did this but my post was deleted because I mentioned a certain cashback.

I got the ebay deal, and I saw this afterwards. It seems the ebay deal has already expired. The additional 4 that I bought just arrived yesterday, and now system is around 40Kwh. These eco-worthy has been great so far for 48V system. I also set up a series battery balancer, but I had to replace it recently. This is more cost effective than the server rack battery.

can i replace this battery with my current 12v on my chevy Silverado?
No. Your vehicle, especially a truck would take 600amps or more to crank. The 200amp BMS would cut the power off. This would be a good choice for an audio system, or for power storage for a RV or something like that.

Do you keep these in your garage or a separate shack just in case? I'm planning my solar system.

Good deal but these are not $1059 normally. Was looking at them a couple months ago on Amazon and they were around $440 each.

I keep mine in a shed, just because it is quite a messy. I don't really care about how it looks as long as it works, but my wife begs to differ. To me, a solar system is a long term investment, I'd get good solar panels (N-type TOPCON is great choice, and don't buy eco-worthy panels). I'd recommend Victron for electronics and get separate MPPT solar charger and inverter. With Victron, you can start small, and expand your system as you go. I don't think that you need expensive batteries, because battery technology changes pretty rapidly these days.

You can use any pwm or mppt solar charger straight to the battery. It all depends on your solar panels and your usage/needs. Your solar panels total Voc should be 20% below your MPPT voltage, and your solar panels total voc should be greater than your total battery voltage (for 12V, this should not be a problem).

If you are converting to A/C (alternating current), I'd recommend at least getting 2 batteries and wire them in series (24V DC) to reduce energy loss (48V is a good compromise).

I was planning to buy two and connect them in series and charge them with two 12v solar connected in series as well. I also want to connect to inverter when they charge is finished. What is a recommended charger that I can use to accomplish this?

No, it is not a simple drop-in conversion from FLA batteries. You may need a different charger/ converter, solar charge controller, and most likely some way to protect your campers alternator from burning out.
Thank you for the information.

How did you get 20% CB? I see 10% for new members (and 6% for me).

What are these used for in always seeing them posted
They have a longer duty cycle. (charge/discharge)
