Thundersky Lithium cells are the latest addition to our product range. I have done some theoretical comparisons between wet cell, AGM, and Gel lead acid, with Lithium. Email me if you want a copy of these comparisons. We have received the first order of Thundersky Lithium cells. Our pack is part of this order. I made a small error in not checking the input voltage to the charger. I had assumed the input was 240v single phase, but it is 380v 3 phase. So this one has to go back and they will sent another one. We will fit our Thundersky Lithium as soon as we recieve the other charger. These cells are 3.2v nominal, so we have 45 cells in series to give the operating voltage of 144v nominal. Each cell is 200 a/hr. This is more useful electricity storage because there is no peukarts effect, like there is with lead acid. Weight is only 7.6kg /cell x 45 = 342 kg. The AGM lead acid currently in use is 64 kg x 12 = 768 kg. A weight reduction of 768 - 342 = 426 kg. We expect that our EV performance will greatly improve. Trev @ drivebynature.com
