Why do you quote power fiqure from metric and imperial - choose bhp or KW, or at least quote both for power and capacity.
35 kwH, means a minimum life of 15mins at a 135 KW draw.
Even an 25% average power draw only gives you an hour. Not too useful
2 hour charge at domestic 110V, single phase? Doubt it, but am prepared to be proved wrong.
I have to say, I love these things. this is the future, fossil fuel burning in large scale efficient plants, providing energy to be used by cars. Battery tech has to catch up but it will.
Any more info on lightning's battery type, is anyonr else using their type?
