The clear advantage I see are 1) Weight 25lb versus 70lb for 100AH capacity 2) 80% usable capacity, versus 50% 3) 3000 cycles, versus 300 so more battery life 4)Robust & leak proof 4) Higher charging current, shorter time to charge if we want to charge on using Main Supply. We should see the price going down in this year, as many folks are getting into manufacturing for the EV autos.
