Really all it is going to take is a step up in battery tec

At 250 amps at 12s thats going to take some serious mah not to kill your liops

Even now byron fans as edf are in the 90 to 120amp range so they use 5000 to 8000mah packs for 4 to 7 min

So doubled the amps double the mah then you will double the weight
