I think about 3600# - I haven't weighed it recently, but it weighed just over 3000 with the 8 Optima YT's. > Frontal area?

I am using about 50 amp/hours on a warmish day, which if my batteries are 225 amp/hr. means that I am at approx. 80% DD - or am I figuring wrong? The E-Meter indicates that I am close to that, and I have a harder time maintaining the 55 MPH speed limit at the end. Most of my commute is at 55 - 60 MPH, with about 4 miles at lower speeds through town. > My longest trip, back then, was 32 miles with the emeter reporting 18% > remaining.

I'm using a ADC 9" with an Auburn Scientific Kodiak controller, which is water- cooled. > Towards the end of my commute I'm down to less than 200 amps. I have a lot of stoplights and stop signs (about 8 of them!), so if I hit them all wrong (which happens occasionally!), I will have a lot of accelerations. I get up to 350 amps on accelerations from a standing stop, but typically draw less than 150 when cruising, except toward the end of the run. The last several miles it takes 200 amps or a little more to maintain 55. Joseph H. Strubhar E-Mail: [EMAIL PROTECTED] Web: http://www.gremcoinc.com > Joseph H.
