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%!

can i use this to charge my ecoflow power station?

Im thinking of connecting it using alligator clips from 12v batt to xt60 to the back of the power station. not sure if this will work and advisable.

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.

can i replace this battery with my current 12v on my chevy Silverado?
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.

If you really want, drag a long 0 or 1 AWG into a spot that has room for the battery.

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.

No. These are NOT starter batteries. That isn't how it works.
