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.

Common Questions (9)

  • The final price has varied a lot because different coupons and PayPal discounts have worked at different times. Buyers reported totals around $240-$280 after stacking discounts, while others saw the code fail or the price rise to about $305-$330 when promos expired.

    Shotgoondesertst0nepootie22apism

  • Yes. It is being used in RVs, campers, boats, trailers, and even for trolling motors, with reports of good real-world performance. It is a large battery, so fit and weight matter, and some users suggest a 100Ah unit may be enough for lighter canoe or occasional use.

    LeakyAneurismproudfootTheNetGuyTealBoundary470

  • Several buyers reported receiving their batteries quickly and intact, and some noted strong store ratings and positive order experiences. Others warned to be cautious because the store identity and refund process on AliExpress can be confusing, so buyer protection is important.

    HiroxosrksiulamGrogan14

  • No. It is a deep-cycle power-storage battery, not a starter battery, and the 200A BMS is not meant for the several-hundred-amp cranking loads most vehicles need. It can run accessories, RV loads, audio systems, and other 12V equipment, but not engine starting.

    jgscott987mblitchyourinsuranceguyCyanRaccoon6450

  • It may, because 12.8V × 280Ah equals 3.584kWh, which is above the 3kWh threshold mentioned for the credit. The battery would need to be installed and used for home power storage by the deadline, and the credit details depend on your situation.

    wildbird12Tazdeviloo7Tazdeviloo7heIIonwheeIz

  • Use a proper solar charge controller for panels, and for power-station charging the input is often limited by the connector and voltage. A standard XT60 setup can be limited to about 8A/100W, while XT60i and higher-voltage series setups can allow much faster charging.

    blupupherimdealingNervousShop859bogelo

  • Runtime depends heavily on the AC's wattage and whether it is running full blast or just maintaining temperature. A standard 13,500 BTU unit running constantly may last under 3 hours, while a lighter 5A 120V load is roughly about 5 hours after inverter losses.

    taz112576ShadowPShotgoonproudfoot

  • No. It usually needs lithium-compatible charging settings and may require a different charger, solar controller, or DC-to-DC charger, especially in RV or alternator-charged setups. It can work well, but it is not a simple swap from flooded lead-acid.

    WasserCptSavAHoCyanRaccoon6450bogelo

  • Yes, it includes Bluetooth, and the listed low-temperature protection stops charging below -7°C and resumes at 0°C. That makes it more suitable for cold-weather use than batteries without charge cutoff, though charging in extreme cold is still a concern for LiFePO4.

i would say no.... Maximum continuous discharge 200Aso 200Amp @ 48V = 9.6KW. so you will be running the BMS in the red zone will only take one hot day and you will pop those transistors in the battery.
You can limit discharge rates on inverters or not have to run that big of load. I was thinking more of a 2500 watt load...

Works but limited 100w need to by pass

Probably. I don't know about that power station, but I do use a 12 V lithium to charge a bluetti power station at times. I do exactly like you've described. Alligator type clips to the DC/PV input.

It's not fast, typically 8-10amps or 100-120 watts input. I get 8.3 amps out of the external battery, 8 amps into the power station. Either a fuse block or an in-line fuse would be prudent for extended charging.

This is a 3.5kwh battery so if "installed" could qualify for tax credit too. Not a tax professional though.
I can't quote where I learned this info or if it's even true, but the charging on your bluetti may be limited specifically at 12v. You may get the full speed of that xt port if you hook up two batteries in series and increase your voltage to 24. Again, do your own research but I hope this info may set you in the right direction.

That's a crazy price for energy storage. I don't think the storage credit still exists, if it did this would be the lowest I had ever seen.
The storage credit is good until Dec 31st however it needs to be 3kWh or more in battery which this is just under

Good price. The lowest end of batteries that won't set your house on fire are around $110 / 12.8v 100ah, and that's without bluetooth. This has the bluetooth which is nice.

Looks like golf carts usually have batteries in the 60-200 amp hour range. With 3 of these, you can probably play 100 holes without recharging... Or you can add a fridge and A/C.You would need to rig up a charge controller that handles lithium. You can read about it online, but there are these different parameters and phases in charging lead vs lithium batteries that these chargers handle. They aren't that expensive. Good luck!

You must have a small AC unit..most AC units use closer to 1350 watts. That battery will last less than 3 hours with a standard 13500 btu unit running constantly.
13kBTU is a fairly substantial amount of BTU for something you're expecting to run off of battery. Many of the wheely AC units are 5-8kBTU.

Do you mean replace your Silverado battery with this Ecoworthy battery? No, that would not work.

It's over 3 kWh:12.8Vx280aH=3.584kWh > 3.000kWh

Right! It is more than 3kWh and can do the tax credit if used for home battery storage. The 280Ah threw me off
