Converting from 12v gell to 8 volt gell

I have a 210 Gem 2 seater. I would like to convert from 6 12 v gell to 9 8v gell any help would be helpful. Do you need to change the algorithm on the D Q charger. where do you find extra space for batteries . Any idea what the range would increase to. Any and all ideas would be appreciated,
