I watched this video earlier today. Seems interesting...used 40 aH w/ 90% capacity for $150 each. I read about them before, but this guy bought some and did a capacity test.
I also came across 12v 100aH batteries out of China for $265 each + shipping. I can get up to 500 kg (30 batteries) shipped to Miami port for $285. This is such a good deal, but I'm just worried about how long will they really last.
