there are people saying their bikes were charging much faster... something doesnt makes sense, im tempted to tell stark about this but their support is very busy right now i dont want to stress them more
I think it can be depend of AC gird voltage
if you have for example 240V on AC then with 16A limit on AC side will give you 3,8kW from wall
battery voltage at 60% should be about 380V so with 10A dc current on charger - in theory you can charge a little faster
for example same with tesla3/y - onboard charger is 11kW and it charge on 0 and 90% with the same rate
however on 0% tesla has even below 300V< and near 90% about 400V
this means for 0% you will need almos 40A to get 11kW, and below 30A at 90%
if you dont have current 16A AC limit then 40A DC at 90% will give you 16kW - and probably its possible bcoz tesla onboard charger max voltage is about 270V
once I was able to put 253V on i got 12,1kW

(if you somehow can put 270v on AC side you will get 13kW)
I hope someone can understand it
