WEAPONS- It has a rear hinged flipping arm, powered by a lem 130 on 60volts

FIRE! I smell a cooked Lem 130.... Lem 130 is a 12-24v motor with the ability to go to 36v with current limiting. 48v is asking a hell of a lot. Check out the specs on the Lemco website, youll find some usefull information on them there.
