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.

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

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

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

  • 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.

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

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

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

  • 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.

Probably a dumb question... say I have a small btu window unit that pulls 5 amps while running. Does that mean I can run it for 280/5=56 hrs? Or is there some other missing variables I need to account for?

Could I run a whole camper trailer (30 amp) for 280a/30a hours?
5 amps is most likely at 120 VAC. You generally lose about 20% efficiency with an inverter.

So let's say its 120 VAC * 5a = 600 Wh
600w * 120% = 720 Wh
3584Wh / 720w = ~5 hours

Right! It is more than 3kWh and can do the tax credit if used for home battery storage. The 280Ah threw me off
don't the batteries need to be "installed" for the tax credit? what is the definition of an installation?

Need some help people .. how do I utilize this to make a backup power substation for electrical outages? Don't need to hook this to panel - I just need ability to charge the batteries, and use the battery to power basic household lamps etc., internet router .. ability to run dishwasher and refrigerator would be great ...
You'll need an inverter to hook up to the battery. I have a 2000W inverter for backup, but you should assess how many watts you'll need for your appliances/chargers.

Installed means being used for home power. I just got 4 of these so basically I wire it and hook it into my existing 48V home system to double the battery capacity. As long as I do it by Dec 31st, it's 100% legit to claim the tax credit. I paid $3300 for my existing 14.3kWh EG4 battery.

I bought 2 of these. Anyone recommend an inverter to use? I am experimenting, wanting to run a small solar setup to run my homelab server (running 100w continuous)

Using two of these batteries in parallel for my camper. They have decent balance out of the box. Be aware they have no overcurrent protection according to Will Prowse. I'm using MRBF fuses on each battery to protect my wires.
What Fuse size did you go with, relative to the size of your wires, if I may ask.....

Question for RVers in SD: Will one of these batteries be sufficient to replace 2 house parallel Marine Gel 12V batteries? Or will it require 2 of these? I just bought 1, but might go for 2. I have a camper van (Class B).

Yes, and no. It might have overcurrent protection now. What is weird is that in his latest video he makes no mention of it not having it the first time he tested it.

9 months ago Will Prowse tested this battery and it did not have overcurrent protection: https://youtu.be/pZm4fa_GjCM?si=9...KXrDA&t=60

However, 10 days ago he tested another one and it did have overcurrent protection: https://youtu.be/MDjB7NAxGZM?si=w...hlw1S&t=95

Still smart to use fuses and circuit breakers regardless.

No. This is way bigger than a car battery. It's for power storage. I got two of them in my trailer. Works well - you can run the air conditioner for 8 hours off them.
No, it will destroy your alternator.

I have a couple of these batteries and am using one of these inverters with each - https://www.ebay.com/itm/376195194079

I have one battery/inverter combo set up in my crawlspace as a sump pump backup. the other one I just have in my utility room and use it for backup power for my refrigerator, chest freezer, and modem/network equipment during power outages. the longest power outage I've had since using this setup is about 14 hours and there was still plenty of juice left in the batteries.
