To me it looks like a much cheaper option if you compare it to something like a Tesla Powerwall or an LG Chem battery, with the added benefit of also having power expandability if you need to increase the storage at any point (again, at a cheaper price point). I saw this Bluetti AC300+B300 on sale for $1200 less, so I was wondering what do you guys think about the idea.
They are extremely overpriced. Build your own
Build your own
Not great advice considering these could easily burn your entire house to the ground if not done properly.
Most people do not have the knowledge and skills to even begin to attempt this.
I have built many LiIon battery packs and it is not a huge savings over buying pre-built packs from professionals. The cells are going to be the primary cost no matter what. Then you still need to get an inverter and charge controller and package it all nicely.
These things are intended for people who like the convenience. Telling them to build their own is equivalent to telling my parents that Ring doorbell is overpriced and they should roll their own solution. You know, bu ya DVR, buy compatible cameras, connect it all and securely exposing it online. Easy right?
