There's no reason to go through your solar input with a 12v battery. Most units has a dedicated cigarette lighter style 12v input for charging from 12v. The reason some people use the solar input is because your 12v input is typically limited to about 10 amps on most power station which means a terribly slow charging rate of right around 120 watts. Many solar inputs wont even except 12v. it's too low. So people will wire higher voltage batteries to the solar input, with the higher the better as long as you don't exceed the max voltage. Most people find 48v batteries work best. Doing this allows you to charge a lot faster from an external battery. Now the max charging speed will be determined by your PowerStations max solar input. In many cases, 600, 800, and even more wattage is doable by charging through your solar input. Doing it like this also leaves your 12v input free so you could still use it to add an additional 120wats of charging on top of what it taking through the solar input.

Community Reviews

This ECO-WORTHY 12V 100Ah LiFePO4 battery is drawing attention as a lightweight, low-cost upgrade for RV, trailer, solar, and backup power setups. The Bluetooth app is reported to work well, and the battery has been used successfully for mini PCs, home assistant, camping, and even as an expansion pack or UPS battery in the right setup. It is also praised for being much lighter than a comparable lead-acid battery and for supporting high discharge use such as trolling motors. The main cautions are that pricing has often landed above the advertised deal after tax, it has no handles, and charging or wiring needs to match the voltage and equipment limits of the system.

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.
