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.

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
Are about 34# each.

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.

Anyone know why they always limit 1 on these batteries?

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?
