Who cares about range in that scenario
Get in there fast and silent, silently lazer all the guards and the compound is yours for the taking... Get a lift back out in a hummer.
So.... Brammo have not explored the military market ?
erm.... life it too short to keep idea's to yourself... So... Could the battery easily run a portable defibrillator unit ? Ventilator's, electric sleeping bag ?
SO many useful items for emergency/first response but they ALL need power and usually have their own battery packs or other forms of power. Apart from the Battery Packs each unit would be REALLY small.
So .......
? ..... If you already have a big battery that your driving to the scene a good selection of helpful emergency stuff can be plugged into it
and as it would be a lot smaller without dedicated battery packs could be neatly popped into a pannier. Maybe even a weapons grade lazer for cutting people out of a car accident.
