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.

Does anyone know if this would be appropriate for a small boat motor?
If you're presently using a SLA @ 12V, I don't see why not. It's a bit heavy to lug every trip, imho, but if you can keep it aboard or very close to slip. Otherwise a 100AH may suffice for occasional use. *https://slickdeals.net/f/18766168-eco-worthy-12v-150ah-bluetooth-lifepo4-lithium-battery-130-free-s-h?p=179973472#post179973472

This is definitely a deal but can't buy more than one in this price. I need 8 of them for 4S2P system. I hope 48V comes with this price range.

Is it just me or there's been a lot of these solar/battery stations on sale lately? Is the industry going under water or they need to move the inventory for "newer" more efficient products?

Thanks OP, just placed an order. Bought 280ah cells straight from the factory and made my own battery box with plywood and threaded rod back in 2021 for twice this price. Crazy how a premade one can be so cheap nowadays

China has over-produced lifepo4 cells, EV sales have declined, we benefit from the dumping of inventory.

Yes. It's a big battery though so make sure you have the space in your golfcart.

Does this have the output that can be used for powering a golf cart? In series.

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.
If you will read, he said he had two of them and ran his air for 8 hours.

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 ...

No one can probably answer this question, but... I need 2 of these for next boating season in about 7 months. They seem to keep getting smaller and cheaper, yall think I should pull the trigger now and store them or wait? Definitely the best price I've seen

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?
