The $132 "Dumfume" LiFePO4 Battery Tested! Holy cow...

It's come to my attention that this company is sending out returned products to other customers. We had it happen on the forum between members. And the 300 amp hour has 280 amp hour cells: https://diysolarforum.com/threads/dumfume-300ah-happy-surprise.98759/page-8#post-1365932

So buy at your own risk. I know some people will complain if I don't link the cheapest product possible but understand what you're getting yourself into:
