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 affordable house, RV, boat, camper, and off-grid storage, with Bluetooth monitoring and enough capacity for serious loads. It is praised for running 12V devices directly, pairing well with solar, and scaling into 24V or 48V banks for larger systems. Real-world reports include trolling motors, backup power, and even air conditioning, though runtime drops fast on heavy AC loads. It is not a starter battery, and charging or wiring often needs the right lithium charger, fuses, and connectors.

  • The battery can be a strong value for energy storage, with multiple reports describing unusually low pricing compared with typical LiFePO4 battery pricing.

    LeakyAneurismantsam9alphawave

  • The battery can integrate into solar and EcoFlow systems, including setups that charge from solar and feed EcoFlow Delta units via XT60i inputs.

    DealMongrDealMongr

  • 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 supports real off-grid and RV use cases, including running an air conditioner for about eight hours in a trailer setup.

    proudfoot

  • The battery can work well for backup power with an inverter, including a reported longest outage of about fourteen hours while still leaving remaining battery juice.

    JuddJ

  • Coupon and checkout reliability can be inconsistent, including reports that promo codes fail to apply or stop working during checkout.

    wildbird12paul2112cx1pootie22paul2112cx1

  • The battery is not intended for vehicle cranking, and it lacks the CCA needed to start a car.

    mblitchCoreyM1264Someguy15

  • The battery can drain quickly with high-power AC loads, and a 13500 BTU unit running constantly was estimated to last under three hours.

    TheNetGuytaz112576

  • The battery may require careful charging compatibility, since some setups report Bluetooth not working and the battery not registering full state of charge with an AC-to-DC controller.

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...

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
