New guy with a $185/kWh pack solution

Hi there. I'm about to post a great deal for a 2kWhr commercial grade Panasonic pack. I'm open to suggestions for vetting or proving that I'm no scammer since I'm so new here. Any questions about me you can ask here or the post I'll be making in a bit. Thanks!

Where are you from? Photos, like lots of them of all the gear you have ready to sell - maybe a piece of paper with secondlifestorage on it or something.. it all helps - end of the day pick up from you personally works perfectly
