<VV> Re:Moving the battery to the trunk

[Shaun]

John, your credentials are impressive, but in simplistic terms:
If you have a 2000 lb. car with 1000 lbs on both front and rear, remove the
30 lb battery from the back, now 970 lbs.,  and put it in the front, now
1030 lbs. you get a 60 lb. weight difference, balance-wise 1030-970=60

the same as adding 60 lbs. to the front, or removing 60 lbs. from the rear.
How can you deny that?

yea, Vairily ... Shaun
