The Big D was designed with two things in mind: heavy duty and light weight. There are two systems available: NiMH and SLA (Lead Acid), both with 110V transformer. Vehicle installation is also possible with 12V plug-in adapter or direct wiring. The charging base (available in Fast or Trickle Charger versions) can be attached to a wall and the quick release design allows you to remove the Big D with one hand.
