Does this work as an expansion battery to power stations?

yes, jumper cables connected to your solar input. Tons of videos out there on how to do it.

I am thinking of purchasing a Pecron and this would be nice to use to expand the watt hours.

I am going to check into this now, thanks for the reply.

The weight of these is so much nicer than a similar sized lead acid battery.

What's the difference between this red case vs the black one with orange label? I like the red case better.

ECO-WORTHY 12V 150AH Bluetooth LiFePO4 seems to be a better deal for a little more

Good Luck, I use the 150ah version with my Bluetti AC200PL, it almost doubles my storage and way cheaper than a Bluetti expansion battery. Keep in mind you will need a way to charge the battery.

Do you have a link to what you use for the battery and possibly explain how you charge that battery extended battery?

I just picked up a cheap one. It takes a while but works great. https://www.amazon.com/dp/B0D7Q5XMGZ i have a a 200w and 400w portable solar panels as well. i plan to eventually get a charge controller so I use them instead of the plug in charger.

Buy 20 of these for around $2,000 and get 25.6kwh total. That's about the cheapest I've seen per kWh. Would be better if if they were 48v for home energy storage though. You'd need to run a bunch in series and parallel for 12v to get to 48v.
