The main focus for us is a reduction in price of the charging hardware but maintaining the same power output and quality. Our system is designed to be paralleled with hundreds of units. so it is well placed to deal with higher capacity battery packs.Say rather that, at current technology levels, 500 Wh batteries are at a popular sweet spot for range/weight/cost. As battery capacities increase we'll soon be expecting 600, then 700 Wh at the same sort of price and weight as we have now. I think there will probably be less demand for smaller, lighter, cheaper batteries at 500 Wh capacity but who knows?
