Thanks, likewise I am in 23832 if you are in the area or anyone else.
I wouldnt toss lead acid out with the bath water.
I was hot and heavy on buying an EV that was for sale because it needed new batteries.
I found out that most local auto stores like Advance, auto zone, batteries express, etc were willing to give a discount for 13 deep cycle group 24 or 27 batteries as well as 13 chargers. I know it wouldnt be the best setup, however it would be cost effective and let me drive around tiwn where mpg is the worse and save the gasser for longer distances.
From what I can see of the Honda IMA system its best to use it for extending coasting and save the gas for acceleration as well as grades. Then of course ensuring it FAS at stops and to coast as much as possible.
