Voltage gains vs weight = run time?

Hv is nice and has alot of advantages, but more care is required as V goes up. Plugging in a 35V battery into a esc w/ empty caps produces a pretty shocking spark. Even plugging into the charger as well.

I doubt it will be std as its a little too dangerous for the careless n00by masses to play with, and good results can be made out of a LV setup. I really really liked the 2Y on 8S I had tho. Very very eff and always cool.
