Buy or build a batery bank?

I have it narrowed down to the Ecoflow delta mini if im going to buy a ready to go battery bank. But ive been watching a ton of videos on building your own.

I am NOT an electrically minded person, but i feel i could get it done.

Has anyone built a bank themselves?

Id want to be able to charge it with solar, the car or plugging it into a wall.

Just looking for experiences or information.

 

What are you looking to power? Lots of diff ways to go about it

I added a solar panel and upgraded my main battery and that’s more than enough to run my fridge / charge devices / etc

I’ve also got a yeti 1500x that I’ve used for base camp and larger power demands.

 

Its going to be running power for a camper shell heater fan, a couple fans for when its hot weather, as well as charging and running various other small electric components like lights, cell phone, tablet.
