Peter, Please explain then. I'd like to understand. If you're taking about 3 miles per *kW out the wall*, becoming 2 as battery age, I agree.
If you look at Wh connected between pack and the drive system, Wh per mile will be the same. You said >>I used to get approx 3 miles per KW,... but didn't say which kW you mean - battery power to move the car or mains power to charge it. That's all. Victor now as the batteries are getting old didn't mention which 2 kW Peter VanDerWal wrote: > > I ment what I said. I have to charge at higher voltages now and > equalize more often.
